• ZTS MBT-1 can test more than 30 different battery types and gives meaningful, accurate readings.
• The ZTS Mini is an affordable and portable alternative. It tests 15 battery types.

The Details

Musicians, professional photographers, hobbyists, parents, and anyone else who is a frequent battery user should invest in a quality professional-grade battery tester. Be cautious of the slew of cheap Chinese battery testers available for sale on the internet. These products do not give an accurate reading, and instead will do little more than tell you whether or not your battery is dead.

Consider the Amprobe, the best selling battery tester on Amazon. It is available for $7, which sounds too good to be true because it is. As expected, it is flimsily constructed and gives iffy reports on rechargeable batteries. As many reviewers noted, it is only good at identifying dead batteries. Worse, it gives inaccurate battery readings and gives artificially high “good” readings on batteries that are on the precipice of death. That can cause unfortunate mix ups, like taking a battery “good” on charge to an important photo-shoot, only for the flash to die after a few snaps.

Luckily, ZTS makes a quality tester that gives a dependable reading. This battery tester is manufactured here in the United States and gives an accurate measurement in a very short period of time. Just place the battery on the nickel-plated brass contact and wait for the bar at the top to show what percentage charge the battery holds.

It tests almost every battery type, including NiMH, Lithium-Ion, Alkaline Lithium, Coin Cells, CR1620 Cells. It has a row of six LED testers that gives percentage reading of how much life the battery has left.

This is not a portable tester — it weighs over a pound and is 8 inches tall.

A Portable Option

If you want a professional quality battery tester that can fit in a purse or glove box, ZTS has the MINIMBT. The Mini is exactly half the MBT: half the size, it can test half the number of batteries (15), and is half the price.

The Mini tests 1.5v alkaline (AA, AAA, C, D, N), 1.2v NiMH/NiCd, 3v photo lithium, and 9v alkaline batteries.

Panasonic’s Eneloop Pro AA Batteries.

These are made with Nickel-Metal Hydride (NiMH) chemistry and have low standard discharge, meaning they can hold a charge for years.

AmazonBasics AA High-Capacity Rechargeable Batteries are a reliable low-cost alternative. They are about 30% cheaper than Panasonic cells, but last only 75% as long per charge.

The Details

Panasonic eneloop pro batteries are high-capacity lower-cycle AA battery popular with electronics reviewers and photography enthusiasts. First launched back in 2006, Sanyo eneloop batteries (since acquired by Panasonic) use eco-friendly NiMH cells designed for use with a wide-variety of products, ranging from flashlights to cameras. Up until the eneloop’s debut, rechargeable batteries were prohibitively expensive and couldn’t hold a charge for anywhere near the length of their alkaline competitors.

Eneloop changed that, but still lacked a little when compared to alkaline batteries or newer competitors. Panasonic’s upgraded option, eneloop pro, can maintain a charge for an extended period of time, with a capacity of 2,550 mAh and Low Self Discharge (LSD) technology. LSD tech is thanks to a highly-durable super lattice alloy that prolongs battery life with increased hydrogen stability that leads a stable voltage output and reduced self-discharge. Expect an eneloop pro to still have 85% of its charge after a year and 70% of its charge for ten years.

What really sets eneloop pro apart is the increased performance in high drain devices, such as DSLR cameras and ultra-bright flashlights. Eneloop pro lasts longer and omits more power in these high power consumption devices when compared to similar NiMH rechargeable batteries on the market. Simply put, these are the best choice for photographers and survivalists.

The added power comes at a payoff, however. Eneloop Pro batteries are among the most expensive NiMH batteries on the market, and last for fewer lifetime charges. Panasonic estimates that an eneloop pro can be recharged 500 times, but number is even lower in reality. Compare that to Powerex’s Imedion AA, which boast 1000 recharges.

Another Option

AmazonBasics offers pre-charged high-capacity NiMH batteries for an affordable price. They are rated at 2400mAh, giving them a longer run-time than similarly priced competitors. They are ideal for everyday uses in low drain devices, like TV remotes and electronic alarm clocks.

Wirecutter found that AmazonBasics did not perform as well in high power devices, such as flashlights and digital cameras.

Date night for two at the movies can easily run over $60 dollars in an urban area once you factor in exorbitant ticket prices, concessions, and parking. All that and you risk sticky seats, texting teenagers, and chatty couples. Making your own home theater is becoming an increasingly affordable alternative to pricey and unreliable nights out at the movies, with quality projector prices falling and pixel counts increasing.

Once upon a time you needed a spacious, cave-like room to make owning a home projector a feasible entertainment option. But the proliferation of short-throw projectors and steadily rising lumen counts mean that projectors are no longer exclusive to suburban basements. Even apartment living rooms can benefit from the immersive experience of an HD projector. You just need to make sure to buy the right projector for you.

There are a couple factors to keep in mind when picking a projector. First, determine the brightness of your room and how large your screen will be. If you do have a windowless room without any source of natural light, you don’t need a high lumen (measure of brightness) count. Likewise, if your projector screen is less than 100 inches, there is no need to pay up for a 4k resolution projector.

Since your projector will likely stay put in your house, things like portability and built-in audio playback aren’t a concern. Instead, consider whether the projector has low lag time, if it has 3D capability, whether it supports media streaming services, what its casting distance is, and image quality.

I’ve identified a few of the best projectors for different consumers below:

The Best 3D Projector

If you are still deciding between an LCD TV and projector for your home theater, a few minutes with a high quality 3D projector will put an end to your waffling once and for all. The latest 3D projectors give a true approximation of the cinema multi-plex experience. Their grand size and gorgeous colors convey the 3D experience in a way that an LCD TV just can’t. Immerse yourself in three dimensions with crosstalk,” the blurry illusion created by two different transmission channels.  Like all 3D technology on the market, there is some loss in brightness when viewing in 3D.

A few alignment options give some flexibility in set up. Lens shifting allows for the projector to be slightly off center from the screen, though you will have to manually do any lens shifting.

The 1700 lumen lamp will last 5000 hours in eco or 2000 at the highest setting. In low and medium ambient lighting, this projector gives bright and crisp colors and HD black. The lumen count is a bit low for bright rooms, so this is best in dens and media rooms.

The HW40ES is sold as a “gaming projector,” and users have the option to use it in a gaming mode that is said to reduce lag. Reviewers have empirically proven that lag time is reduced to 24 milliseconds, which is one of the absolute best for gaming.

It does not come with 3D glasses, so you will need to invest in a pair that is compatible with Sony projectors.

The Best 4k Projector

For those that want only the best image quality, sharpest contrast, and latest tech, a 4k projector is the way to go. 4k is the new gold standard for video resolution. The new video technology refers to the 4,000 thousand pixels found alongside the horizontal line display. Right now, Sony enjoys a total monopoly of the 4k home projector market. Of the 4k projectors Sony offers, the VPLVW350ES SXRD is the best value for an unbeatable image.

This behemoth of a projector weighs close to 40 pounds and is a commanding 25.1 x 22.9 x 12.6 inches. Inside comes Sony’s SXRD 4k movie theater technology and anamophic 3D capability. This top of the line tech enables you to cast onto a larger screen than some 1080p projectors. Sony says that full brightness (1500 lumens) and resolution are achieved on a 150 inch screen.

Since 4k is relatively new, not a whole lot of media is specifically made for 4k resolution. This is definitely changing, but 1080p HD is still the standard as of now. Sony equipped with the 350ES with Super Resolution upscaling so you can enjoy your content in 4k in the meantime. It uses a ‘Mastered in 4k’ algorithm to upscale HD movies and shows into 4k content. Sometimes this results in a noticeable difference, other times its hard to make a meaningful distinction.

The VPLVW350ES SXRD comes with a 3 year warranty.

The Best Projector for Football Fans

Plan to marathon NFL games all Sunday? You will need an extra bright projector if you are going to set up your home theater in a room with any natural light sources to get the most our of your daytime viewing. The brightest home theater projector is the Epson Home Cinema 1440, which has a staggering 4400 lumens.

This model uses 3LCD projectors for Full HD 1080p images that are rated three times brighter than other projectors in its class. This means you get stunning HD imagery in well-lit rooms, even with all the blinds up.

Easy slide horizontal keystone correction and automatic vertical keystone correction make alignment relatively easy. However, a lack of lens shift means you have to mount the projector dead center from where the image will be projected. This model is also lightweight and compact for a home theater projector, weighing just 13 pounds.

Ultraviolet light is the preferred light source of TV crime scene investigators on the hunt for body fluids. Distinguished by its trademark purple glow, it has a wavelength that is shorter than visible light but longer than X-rays, in the range of 10 nanometers to 400 nanometers. It is useful to make fluorescent substances glow that can’t otherwise be seen by the naked eye. Portable UV light used to be too unwieldy and expensive for consumer purposes, but that all changed after ultraviolet light emitting LEDs were introduced in 2006. They are now widely available in flashlight form.

These flashlights are most often used to detect fraudulent documents such as fake IDs, see watermarks, read invisible ink or investigate crime scenes. They can also be used to “fluoresce” scorpions and certain types of minerals, and charge “glow-in-the-dark” object like fishing lures. Use them to protect your businesses from counterfeit money and your home from pointy tailed pests.

Gallium Indium Nitride UV Flashlight

This Gallium Indium Nitride UV flashlight gets great ratings from Amazon buyers, so we thought we’d include it here. Reviewers were impressed by the flashlight’s durability, and the fact that it emits 365 nm UV light, which is at the very edge of our visible range. The light from this flashlight appears as a dim purple-blue to the eye, but when it shines on items that fluoresce they light up brightly.

It uses three AAA batteries — we recommend using low self-discharge AAA rechargeable batteries like Eneloop Pros in this flashlight.

Here are some reliable speaker dock that still allow you to dock your iPad and immediately play your music:

Sony RDPXF300IPN Lightning iPad Dock

The Sony RDPXF300IPN Lightning iPad Dock is the best sounding speaker dock I’ve tested. The two speakers output 20 watts each, and have a rich and bright sound. In fact, this dock sounds better than the Bose SoundDock Series III (which also lacks bluetooth connectivity and a remote control).

This dock has an internal lithium-ion battery so it can be used as a portable player, it also features a radio and a remote control.

The Sony RDPXF300IPN Lightning iPad Dock is available from Amazon for about $300.

iHome iDL48BC Dual Charging Portable Rechargeable Speaker

The iHome iDL48BC speaker dock is a good budget choice for a speaker dock. It delivers resasonably good sound, but it lacks some of the clarity and bass of the Sony RDPXF300IPN.

The iHome iDL48BC is available from Amazon for about $80.

The reputation that USB tables are junk doesn’t have anything to do with the fact that they are USB. It has everything to do with the cheap materials that they are made from. A turntable consists of many precision parts, including the arm, the platter, the plinth, the motor and the cartridge. Most USB turntables are all about style (or budget) over substance. So long as it looks good in a sepia-filtered Tumblr photo, does it really matter how the thing sounds? The problem isn’t just that they look and sound cheap (many play music at an abysmal 128Kbs). But some of these players, like the Crosleys you see at Urban Outfitters, use non-changeable ceramic cartridges that have a heavy tracking force that damages records. Why even spend the extra money?

In other words, most USB turntables are not made with the audiophile in mind.

Best USB Turntable For Digitizing Vinyl: Sony PSHX500

So what happens if you are sitting on boxes of vinyl that need to be converted to digital for posterity’s sake? That’s where the Sony PSHX500 Hi Res USB Turntable comes in. Its cartridge isn’t the best on the market and it isn’t packed with a ton of features, but this is the first device that converts to digital in high resolution.  The PSHX500 is also almost completely customizeable, a fact that sets it apart from most other USB turntables.

So how good are the recordings? Sony uses a patented circuit that the takes the record’s signal and converts it into a digital audio data stream using a Burr-Brown PCM4202 analog to digital converter. You can record files in everything from WAV to  double DSD (although good look finding a vinyl that will rip at 5.8MHz).  After you rip a track, the file appears on Sony software, which lets you choose the file format. It also lets you do some basic manipulation, like rearranging the tracks.

Now, you don’t always get a perfect recording. Some reviewers noted a faint humming in the background. But this is bar-none the best commercial option available for getting those rare options off wax and onto silicon. The process is also incredibly streamlined. You just plug the USB from the device into the computer, drag the needle, and hit play. Finally, you can digitize your records.

I like the minimalist matte black design for home use. It’s modern and goes well with polished dark wood cabinets and exposed brick and all the other staples of 2o10s interior decorating. The bare-bones approach means you are forgoing DJ staples like reverse function and pitch range. You get two speeds: 33 and 45 rpm(78 is missing, so don’t plan on converting those).

The Sony PSHX500 is outfitted with a moving magnet cartridge that is fit at the top of the arm. It is a fine cartridge, but audiophiles will want to switch in their preferred one. It also has a built-in phono preamplifier with RIAA curve, which is a nice feature for a turntable in this range. If you would rather play through your own phono EQ, just switch off the built-in one. It also has a removable lid and and integrated shell for solid stabilization.

All in all it is a durable piece of equipment, with a belt system that uses spindle-bearing construction. The platter is aluminum die cast and the mat is rubber, so that’s good. The spindle hinges are worrisome. I don’t recommend this unit for DJs who are going to be transporting their equipment around, but it will hold up in a stationary environment for a long time.

Best USB Turntable For DJs: Audio Technica AT-LP1240

Hauling a turntable around to parties and shows necessitates a device that can withstand wear and tear. The Audio Technica AT-LP1240 is a professional quality DJ turntable that is equipped with an internal stereo phono pre-amp and a high-torque motor. The thing is built to last and weighs like it.

If you are drawn to turntables for their retro aesthetic, then the blue LED lights and the slick pitcher and controls on the LP1240 won’t appeal to you. The turntable platter is made with die-cast aluminum, an S-shaped tone arm with counterweight, and anti-skate adjustment. These quality components are held together in a futuristic black and silver design. The LP1240 is a 3-speed fully manual and comes with plenty of ways to keep your speed accurate. It also has a a high quality brake. DJs also get a target light for dark clubs, two start/stop buttons, a reverse function, and a pitch change that goes to 50 percent over or under record speed.

You can plug right in to your laptop via USB and record using Audacity software. It doesn’t come with a cartridge so you will have to supply your own. You won’t find a better turntable in this pricerange, USB or otherwise.

I enjoyed every minute I spent with the RTi A1. The speaker’s greatest strengths — the natural and detailed midrange, the excellent bass extension — are unheard of at this size and price, and its minor deviations from neutrality have been so carefully thought out and balanced that I wanted to mine my entire record collection, playing more and more different types of music.

A total of 32 reviewers on Amazon rated them an average of 4.9 out of 5 stars.

The RTi A1 speakers from Polk Audio are available from Amazon for about $255.

Another excellent speaker brand is Bower and Wilkins. If your bookshelf speaker budget is around the $500 range, you might want to check out the Bower and Wilkins multimedia speakers.

• Newegg.com: 5.0/5.0 (225+ reviews)
• AudioEnz: “A fine sense of extension, tactile impact and all round bass weight and authority”

The Polk Audio PSW505 is an established and respected player in the large-room subwoofer game. Its performance is class-leading, with deep reserves of thundering bass and incredible precision. The PSW505 is a 12-inch woofer with a frequency range of 23 to 160Hz. It is solidly-built, measures 16-1/8″ H x 15-1/8″ W x 18-3/16″ D, weights 43 pounds, and is wrapped in black, real wood veneer. Features include an adjustable low-pass crossover, volume control, and a phase switch. This sub is magnetically shielded against interference and has an auto on/off switch to conserve power. Inputs are 5-way binding posts, line level (filtered), and LFE (unfiltered); output is a pair of 5-way binding posts. The PSW505’s 300 watts of power and big volume potential make it best suited for large spaces.

Amazon sells the Polk Audio PSW505.

Polk Audio PSW10 ($94)

Pros:

• Solid construction
• High value
• Clean and clear sound

Cons:

• No LFE input
• Might be insufficient for large rooms

Top Review Sources:

• Amazon: 4.5/5.0 (375+ reviews)
• CNET: 3.5/5.0 “It pounds out home-theater thrills and musical bass with equal prowess”
• Newegg.com: 5.0/5.0 (225+ reviews)

The low-price, high-performance Polk PSW10 makes it difficult to justify building a home theater without a powered sub. For $100, this subwoofer delivers 50 watts of continuous power through a 10-inch composite polymer speaker, producing rich bass with plenty of punch. Equally skilled at enhancing music, movies, or television, the PSW10 does its job without becoming boomy or muddled at high volumes. Its solid construction contributes to its great sound: 26 pounds of medium-density fiberboard measuring 14-3/8″ H x 14″ W x 16-1/8″ D. Included are speaker-level and line-level inputs, plus a speaker-level output. Frequency response is 35 to 200Hz. You also get on-speaker volume, crossover, and phase controls as well as an auto on/off switch. The PSW10 is built for small- to medium-size spaces. It is available in black or cherry finishes.

The Polk Audio PSW10 is currently available on Amazon.

Definitive Technology SuperCube III ($379)

Pros:

• Small package; huge bass
• Great range
• Solidly built

Cons:

• Will distort at extreme volume

Top Review Sources:

• Crutchfield: Staff Pick “True, accurate, and extremely deep bass in any room”
• Best Buy Customer Reviews: 4.5/5.0 (15+ reviews)
• Home Theater Magazine: “other SuperCube subs…have had amazingly low but very musical bass output—and lots of it. The SuperCube III is no exception”

Definitive Technology’s SuperCube III produces unbelievable bass despite its compact footprint. Its sound profile is defined by its extreme depth—all the way down to 16Hz. The SuperCube III produces an authoritative 650 watts of power, capable of handling the bass duties in small or large rooms. Listeners appreciate the SuperCube III’s versatility; it performs as well when asked to provide a steady, undistorted rumble as it does when the soundtrack demands rapid, staccato bursts of bass. Though this gloss black cube weights a substantial 25 pounds, it only measures 10-1/4 inches in any dimension. It has a signal-sensing auto on/off switch, low-pass crossover, volume control, 5-way binding post outputs, and line level, LFE, and 5-way binding post inputs. Its woofer is 7-1/2 inches in diameter.

You can buy the Definitive Technology SuperCube III on Amazon
