Bring Out the Reserves

Never get caught with a dead phone again: refuel all your gadgets on the fly with one of these high-capacity backup chargers. 1. Innergie PocketCell $80; www.amazon.com The 2.5-ounce PocketCell earns our highest praise, thanks to a smartly designed cable that holds mini-and micro-USB connectors(for the portable electronics), as well as Apple's proprietary 30-pin one. This lets you change any device, without having to stow spare cables. Though it has the smallest battery, it supplied more than half the jice to a Kindle Fire. We also used it to revive a dead iPhone to full charge. 2. Mophie Juice Pack Powerstation $80, www.mophie.com The elegant backup's high-output battery delivered the fastest charge, juicing an iPhone in 90 minutes. It can fill an iPad to 60% or provide two full phone charges, and it's certified for 500 cycles, making it the most durable in our test. Impressive, nut we wish it offered more than one USB port. 3. Scosche GoBat II $80, www,scosche.com The beefy GoBat, which looks like a portable hard drive, can charge two devices at the same time. It pairs with Scosche's Revive app, which tracks such info as how long plugged-in devices need to refuel. Despite measuring 5 by 3 inches, the GoBat charged an iPhone only twice and iPad to 60%; charging the unit itself took a full seven hours - a bummer considering it's the biggest one here. 4. Tylt Powerplant $60, www.sprint.com Flip down the Tylt's front flap to expose its USB port and swinging arm - the arm can be customized with a 30-pin or micro USB. Its battery, the biggest of the group, refueled a depleted tablet on one charge, but its build quality left something to be desired: Its arm made charging devices awkward, and the flap fell off our test unit. Look elsewhere. HAPPY EASTER EVERYONE - HAVE A FANTASTIC WEEK! :)
