iWalk Extreme 7500 Backup Battery: Go-Anywhere Power for (Almost) Any Device Mike Richard January 8, 2013 First Look, Gear, Modern Vagabond The mobile power market has exploded in the past year, meaning travelers rarely need be without juice for their portable electronics. Thankfully, backup batteries have become increasingly small, yet even more powerful. Such is the case with iWALKUSA’s Extreme 7500 rechargeable universal backup battery. The Skinny In the manufacturer’s own words the Extreme 7500 features: Rechargeable universal backup battery in a stylish design. Superior quality with stylish compact design from Korea. Impressive 7500mAh lithium-ion battery with 5V/2.1A rapid output. Compatible with many devices. Smart circuit protection design keeps your devices from overcharging. Charge your device and phone at the same time. Dust-proof, rubber plug in the DC IN/OUT port and hand strap hole. Certified by Apple, this product is safe and reliable. The Traveler’s Take There are plenty of portable battery solutions available. The main win for travelers with the 7500 is its balance between size and capacity. Not much larger than a Snickers bar, it’s a no-brainer to toss it in your pack. And its 7500 mAh output is powerful enough to charge just about any mobile device, up to and including iPads. That and the fact that it’s compatible with any device that charges via a standard USB cable should satisfy most travelers. Just about the only thing it won’t charge is a netbook or laptop. If you’re looking for that kind of juice, step up to iWalk’s Extreme 8200 or Extreme 15000. The latter puts out a whopping 15600 mAh of power – plenty capable of charging even a full-sized laptop. Pricing & Availability Available now in black or white directly from iWALKUSA for around $90 (USD).
