The dual-port New Trent iCarrier packs a punch with 12,000 mAh that can power up tablets and phones simultaneously. At 9 inches long, it's rather big, however, and while the iCarrier charger gets mostly positive reviews, some users maintain it has quality issues.
Good for packs, not pockets. New Trent's iCarrier 12,000 mAh is a powerful portable charger but isn't the smallest or lightest device, measuring 9 inches long. (One review notes it's about one-quarter the size of an iPad, though it's a bit wider.) The dual-port iCarrier is fine to carry in a backpack or purse, users say; it is built with a semi-glossy black plastic case, however, so it isn't the most durable. A more rugged version of the device, the PowerPak Xtreme, (Est. $50) is water-, dirt- and shock-proof. The iCarrier can charge two devices simultaneously via its two 5V USB ports. The labels on the ports aren't terribly intuitive, though, simply reading Output 1 (1 amp for phones, iPods and other smaller devices) and Output 2 (2.1 amp for tablets). A battery-level indicator reads Low, Mid or High, and the iCarrier shuts off automatically when a device is fully charged. While the iCarrier comes with a standard travel bag, no cables are included.
Not for the occasional user. The iCarrier can charge tablets and phones or smaller devices simultaneously, and is good for up to 500 charges. Several dozen consumers on Amazon.com, however, reported that their iCarriers died well before then, which apparently compelled New Trent to extend its warranty from six to 10 months. The company also warns on Amazon.com that the product must have the official New Trent logo for the warranty to be honored, indicating that there might be fakes lurking online. (The product has an impressive 4.6-star rating from about 2,400 Amazon.com reviewers.) The charger has enough juice to power up a tablet or charge an iPhone two to four times, users report. In one test, it brought an iPad 4 from 25 percent to nearly full in a little over five hours. The iCarrier needs to be fully charged prior to its initial use, and the battery must be drained and recharged at least once a week for best performance, Amazon.com users say. The iCarrier can't be used while recharging, and the fastest recharge (about eight hours) can be had by using the New Trent NT90C wall-socket charger (Est. $10) which is sold separately.
About 2,400 Amazon.com contributors give the New Trent iCarrier 4.6 out of 5 stars overall. (The reviews date back to 2010 and include previous versions.) Reviewers are generally impressed with the iCarrier's performance and design, but several dozen say it died quickly.
Review: New Trent iCarrier 12000mAh, Contributors to Amazon.com, As of April 2014
ILounge.com, an Apple reviews and products site, gives the iCarrier an A- or Highly Recommended rating, thanks to its strong performance in tests (it powered up an iPad 4 from 25 percent to 96 percent in a little over five hours) and its recharge time (eight hours) using the iCarrier wall socket. Like most iCarrier reviews, however, this one is slightly dated, and New Trent has changed the iCarrier several times -- it no longer comes with a wall-socket charger, for example (that's now sold separately).

This is a short write-up of the iCarrier, which is named as one of six recommended portable chargers. The charger's 12,000 mAh is double that of others listed, including the Mophie Powerstation Duo and the ZAGGsparq 6000.

This is a short review of the iCarrier's design and features; the reviewer doesn't test the charger. He praises the battery's 12,000 mAh capacity and its "slick feeling black plastic shell."

A poll of Lifehacker.com readers rates the New Trent iCarrier and iGeek second in popularity to the Anker Astro series. Readers like its ability to charge phones multiple times before dying; in addition, Alan Henry says, "it holds a charge forever, and the easy-to-read indicator lights on the top of the device never leave you doubting how much charge your unit has left."
