The mini Innergie PocketCell can be used to power up a smartphone (up to 15 hours) or tablet (up to five hours) and automatically shuts itself off to save the battery. The PocketCell comes with a 3-in-1 cable (the cord has a mini USB, micro USB and 30-pin Apple connector all in one), but doesn't win the rave reviews of other pocket-sized portable chargers.
Sleek, Apple-like design. Released in 2011, the Innergie PocketCell is an older product in the world of portable USB chargers, but it's still a popular choice for a mini charger. The PocketCell is about the size of a lighter and has a sleek, simple design. "It could probably pass for an Apple product if it had the requisite logo," notes David Carnoy of CNET. It weighs 2.6 ounces, similar to competitors like the Best Reviewed mini portable charger, the Powerocks Magicstick (Est. $30) , and the Anker Astro Mini 3,000 mAh (Est. $20) . Unlike those two chargers, however, the PocketCell comes with a 3-in-1 cable that includes a micro USB, mini USB and Apple 30-pin connector that is very popular with consumers. A four-light battery indicator shows how much juice is left; the PocketCell turns off automatically if not used for 10 seconds.
A "just fine" charger. Innergie PocketCell's many attributes -- bonus USB cords, compact design and 3,000 mAh capacity, higher than many of its competitors -- still don't propel it to the top of the list among mini USB chargers. The PocketCell can easily charge smartphones or tablets thanks to its 2.1 amp capacity, and its performance isn't bad, but consumers and reviewers seem to prefer newer, cheaper, lipstick-sized chargers. It performed "just fine" in CNET's tests with an iPhone, iPad 3, Kindle Fire and Samsung Galaxy S III, but didn't charge "extremely quickly." The PocketCell charges an iPhone about two times before dying, but a handful of Amazon.com reviewers say their products were defective and that Innergie wasn't responsive to their concerns. Given its so-so performance and PocketCell's high price point for a mini charger, many users and reviewers say you can get more bang for your buck.
1. PC Advisor
U.K.-based website PC Advisor gives the PocketCell 3.5 out of 5 stars, largely based on its price point, which has since dropped. In editors' tests, the PocketCell charged the iPhone 4s in just under two hours and charged a second iPhone at 19 percent before dying. The PocketCell only charged the iPad 2 from empty to 27 percent.
