The Best iPhone Chargers Of 2012

by Justin Thomas •

dreamGEAR i.Sound Portable Power Max

Today, we use smartphones and tablet computers wherever we go. However, batteries life tends to be a constant issue. That’s why carrying a spare USB charger in your daypack or purse makes a lot of sense. In most cases, you just need a bit of power to make a call or access the internet.

USB chargers all contain a rechargeable lithium-ion battery, and a USB socket that outputs 5 volts. The difference is the power capacity of the batteries inside the chargers, and this capacity is measured in milliAmp hours (mAh).

PowerGen External Battery Pack (5200 mAh)

Rating: 4.5 out of 5 stars from 114+ reviews on Amazon

If you just want to charge a smartphone or a USB device with modest power requirements, the PowerGen Duo-Power USB Battery Pack is solid and inexpensive option. The charger has a capacity of 5200 mAh — enough to fully recharge a iPhone 4 twice. It can also partially charge an iPad (to about 30% to %50 percent of capacity depending on the iPad model).

The Powergen Battery Pack takes about 1.5 hours to fully charge a smartphone, and the Battery Pack itself takes about 5-6 hours to be recharged (when plugged into a wall socket). It also features a flashlight that runs for 250 hours.

The PowerGen External Battery Pack  sells for about $34 on Amazon.

The New Trent iTorch charger is very similar to the PowerGen charger, but the PowerGen is made of better quality materials, looks nicer, and is only half as thick as the New Trent charger. However, the New Trent charger does have a very convenient retractable USB cord.

There’s also a PowerGen Duo-Power USB Battery Pack, which has two USB ports and a capacity of 8400 mAh. It sells for about $50 on Amazon.

New Trent iGeek IMP99D (9900mAh)

Rating: 4.6 out of 5 stars from 285+ reviews on Amazon

The New Trent iGeek IMP99D charger stores 9900 mAh, which is almost twice the battery capacity of the PowerGen charger featured above. This means it can fully charge an iPad 2, or charge an iPad 3 to 60% of full charge.

This charger is won’t fit in your pocket — it’s about the size of two cellphones placed side-by-side. It features two USB charging ports.

The New Trent iGeek IMP99D charger is available for about $65.

 

New Trent IMP500 ($40)

The New Trent IMP500 is a 5000 mAh external battery for the iPhone 4. The IMP500 is also compatible with the iPod Touch and Classic as well as the majority of modern smartphones. It will charge a Kindle, Nintendo DS, or Sony PSP with separate, non-included adapters. The manufacturer claims the IMP500 will increase the iPhone 4’s battery life by 300% — 25 total hours instead of the iPhone’s usual 6. Reviewers generally confirm this claim; there are very few complaints of battery underperformance. Some reviewers point to the smallness of the included mini- and micro-USB adapters and express concern over their tendency to disappear, but this is not a widespread criticism. The IMP500 features a charge indicator and retractable USB cable with AC wall charger. The IMP500 weighs six ounces and has dimensions of 4” H x 3” W x 0.75” D.

The New Trent IMP500 is currently available on Amazon for about $40.

 

Mophie Juice Pack Air ($75-80)

Top Review Sources:

  • PC Magazine: 4.0/5.0 “Its excellent performance and relatively reasonable price make it our Editors’ Choice for iPhone 4 battery cases”
  • Amazon: 3.8/5.0 (237+ reviews)
  • Engadget: “The Mophie was clearly loved and cuddled as it progressed from art to part”

The 1500 mAh Mophie Juice Pack Air will nearly double the battery life of your iPhone 4. The Juice Pack Air is a form-fitting protective case/external battery combo. You charge it via the included USB cord — the Juice Pack Air doesn’t need to be removed to be recharged. A four-LED indicator on the bottom gives you a report on remaining power. The Juice Pack Air comes in two pieces — you slide your iPhone into the case, then slide on the top edge of the case to lock it all together. The Juice Pack Air provides power to your iPhone only when you flip its side switch. Cutouts for volume, headphones, camera, etc. are well-aligned when the Juice Pack Air is in place. Despite its sleek profile, the Juice Pack Air will noticeably swell your iPhone 4. With the Juice Pack Air installed, the dimensions are 5.07” H x 2.51” W x 0.68” D—without it, the iPhone 4 measures 4.5” H x 2.31” W x 0.37” D. The Juice Pack Air increases total weight from 4.8 to 7.3 ounces.

The Mophie Juice Pack Air is available in black ($75)red ($80), or white ($80) from Amazon.

PhoneSuit’s Primo Power Core is an 8200 mAh portable battery charger capable of charging an iPhone four or five times; it can fully charge an iPad once.

The Primo Power Core has a single USB charging port. Use the included USB cable and eight charging tips to connect your iPhone or other mobile device. The Primo Power Core also includes a 12v output port, useful for electronics like netbooks. Inside the box you’ll find a carrying case and AC adapter.
