• EBL 3.7V Li-ion Rechargeable Batteries — 3000 mAh
• Kiminors 3.7V 18650 Rechargeable Battery — 3200 mAh

Our recommended 18650 battery charger: XTAR VC2

About 18650 Batteries

What are the advantages of 18650 batteries? They are 3.7-volt lithium-ion batteries that can be recharged and are compatible with a wide range of electronics, including laptops, digital cameras, flashlights, and even electric car batteries.

Panasonic, Sanyo, Samsung, and LG are the top level 18650 cell manufacturers, making long lasting cells in a standard size (18 mm by 65 mm) that fits all 18650 compatible devices. Chinese knockoffs are available for cheaper but are prone to shorter lifespans and aren’t always uniform in size. As a rule, be wary of “protected” 18650 batteries, which have small circuit boards at the bottom that do not fit some electronics, such as flashlights.

High-drain batteries are safer and designed for high current devices, such as vaporizers. They are also less wasteful, meaning they have a longer life cycle and can last for more recharges.

18650 Battery Chargers

The best part about 18650 batteries is that they can be recharged. That means you will need a reliable charger to keep them energized and in working order. I like the XTAR VC2 charger because it has an informative LCD screen display.

The LCD screen tells you the real mAh capacity of your batteries, so you can make sure they are getting the advertised amount of fill or identify when they are losing efficiency.

• For well water or other problematic water, I recommend Big Berkey drip filters. These filters use a combination of ceramic and carbon block filtration. Overall, they are the least expensive type of filters to maintain.
• If you are only interest in a pitcher filter — this BWT filter will remove most contaminants
• If you are able to spend $1500 to $3000, “whole house” filters are the an inexpensive long terms option. These filters are installed at the pipe where the municipal water pipes enters your home. I recommend the whole house filter by Pure Effect.

The Contaminants You Want To Remove

Typically, you want to remove these contaminants from your water:

• Toxic metals (Lead, Mercury, Aluminium, Cadmium, Chromium, Copper, etc.)
• Additives (Chlorine, Chloramines, Fluoride)
• Chlorination By-Products (Trihalomethanes or THMs)
• VOCs and other Organic Compounds (Pesticides, Herbicides, Pharmaceuticals, Fuels)
• Bacteria and viruses (Giardia, Cryptosporidium, etc.)
• Radioactive substances (Radon and Uranium, etc.)

If you use municipal water, you will usually find these contaminants:

• Chlorine
• Chloramines
• Fluoride
• THMs (Trihalomethanes)
• VOCs (volatile organic compounds)

If you use well water, these are the most common contaminants you’ll find:

• Particulate matter (dirt, bits of leaves, etc.)
• Bacteria and viruses
• VOCs (volatile organic compounds)
• Radioactive substances

The Effectiveness Of Different Types Of Water Filters

Pitcher Filters

Pitcher-style filters such as Brita filters are inexpensive units, making them very popular with consumers. However, in the long term, they are actually one of the most expensive option. The filters cartridges require frequent replacement — the cost for 40 gallons is $7-10 each, or $130-$190 for 750 gallons.

Almost all pitcher-style filters use GAC or “granulated activated carbon” as the filtration medium. Typically, GAC is coconut husks that have been heated to a high temperature in the absence of oxygen and then granulated. These filters do remove some chlorine and hydrogen sulfide (rotten eggs odor) — but are not effective at removing VOCs, metals, pesticides or fluoride. Overall, they are not very effective water filters.

Faucet Filters

Filters that attach to your kitchen faucet are very similar to Pitcher Filters, but they do filter a little better than the pitcher-style filters. However, they have the same drawbacks — they are expensive to maintain and they do not remove many contaminants. You must replace filters every 100 gallons at $20-$40 each or $140-$180 for 700 gallons.

Colin Ingram, author of the The Drinking Water Book rates all faucet filters no higher than “Acceptable”.

Gravity-Fed Drip Filters

In my opinion, the best water filters are gravity-fed drip water filters. These filters are excellent at removing chlorine, chlorination by-products, fluoride, VOCs, pesticides, particulates and pharmaceuticals. These filters use “candle” type filters, which are widely available and can be customized to your specific filtration needs.

Gravity-fed filters require no electricity to operate — water is filtered as it drips from the upper chamber to the lower chamber. Because the water is filtered slowly, the filtration is much more effective than a faucet-mounted filter. Generally, slow filtration methods tend to be best.

Berkey is best-known drip filter manufacturer. They make good quality filters. You might also consider ProPur filters. Their latest filter, the ProOne G 2.0, will remove fluoride — including hydrofluorosilicic acid (few filters remove this contaminant).

These filters use carbon block filtration, which works by the process of adsorption (different than absorption). In this process, the carbon attracts certain contaminants at the molecular level, and the contaminants become attached to the surface of the carbon. Once the surface of the carbon is full, the filter must be thrown out and replaced. However, the ProPur filters can be periodically scrubbed, and thus reused for years.

These filter are certified to NSF/ANSI standards #42 (test for chlorine, taste, odor and particulates), NSF Standard #53 (tests for Cryptosporidium, Giardia, lead, VOCs and MTBE) and NSF Standard #61 (tests that toxins aren’t leached into water). They are manufactured in England.

Berkey filter are available from Amazon for about $300.

Overall Rating: Excellent

Reverse Osmosis Filters

Reverse Osmosis filters use a membrane which removes many contaminants from water. They are usually paired with a Granulated Activated Charcoal filter to remove chlorine. Most reverse osmosis filters are installed under the sink and have a holding tank. The semipermeable membrane separates many contaminates (which usually have a larger particle size that water) from the water and rejects a large amount of water in the process. The result is a waste of several gallons of water for every gallon filtered and many naturally occurring minerals (including calcium and magnesium) are also removed from the water.

However, they are quite effective filters, in terms of removing contaminants. However, they do not reduce VOCs or pesticides (unless a Carbon Block filter is included). They can take up to an hour to filter one gallon of water and the filters need to be replaced regularly.

If you want to go this route, I recommend the iSpring Reverse Osmosis System, which is quite reliable.

Overall Rating: Very Good

Countertop Distillers

Countertop distillers are effective water purifiers, but they take some time to distill water (for example 5 hours to distill 1 gallon). They also require electricity to run, and they give off some heat and the integrated fans make some noise. Also, most distillers do not remove VOCs (like benzene) because they have a lower boiling point that water. So they will vaporize together with the stream, resulting in a contaminated distillate.

Countertop distiller that get a rating of “Excellent” from Colin Ingram in the The Drinking Water Book are: Megahome Countertop Distiller, Waterwise 4000 and Waterwise 8800, Kenmore 34480 and Pure Water Mini-Classic.

Megahome Countertop Water Distiller

This distiller is sold under many brand names — it’s the most widely distributed distiller in the world. It has many quality components despite being inexpensive. It produces 1 gallon of water in 5 hours. The water is passed through a small granular carbon filter. There’s a sealed connections from the distiller to the water collection container, so there is minimal risk of contamination by air. The unit has a stainless steel boiling chamber that is easily accessible for cleaning.

The Megahome Countertop Distiller is available from Amazon for about $150.

Waterwise 4000 Countertop Distiller

This is a more powerful version of the distiller listed above. It has the same features but produces 1 gallon of distilled water in 4 hours. Also received an “Excellent” rating from Colin Ingram in the The Drinking Water Book.

The Waterwise 4000 is available from Amazon for about $320.

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.

Currently, the best rechargeable C-size battery is the ELB 5000 Battery. A pack of 6 costs $24.

About C-Size Batteries

Although they are no longer as popular as they used to be, C-size batteries are one of the most common alkaline batteries today. They have kept the same dimensions (50 millimeters by 26.2 millimeters) since 1926 and are used in medium-drain electronics such as toys and instruments. Disposable 1.5V alkaline dominated the C battery market for years due to its high capacity and long shelf life.

Rechargeable C-size batteries are rapidly gaining marketshare over their throw-away counterparts, thanks to crucial technological advances within the past decade. Instead of alkaline, they are using 1.2V Nickel-Metal Hydride Chemistry (NiMH) that allows for greater capacity that doesn’t atrophy after long stretches of inactivity. Whereas in the past rechargeable batteries would drain by themselves via discharge even when they weren’t in use, they now retain up to 85% of their charge capacity for months at a time. No more pulling out a rarely used flashlight the night before a camping trip only to find that the charge has evaporated in your garage.

Of all the rechargeable batteries on the market, ELB offers the best C-size battery. The 1.2V NiMH cells have a 5000mAh capacity, almost as much as the standard 8000mAh of disposable alkaline batteries and much higher than other NiMH cells, and close to the capacity of a lithium cell.

For a charger, I recommend the Maha PowerEx MH-C808M. This smart device can charge 9 C-size batteries at a time.

The Details

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.
