Just Mobile Gum++ Backup Battery [REVIEW]

Introduced by Just Mobile earlier this year, Gum++™ backup battery is the company’s latest offering in its ever growing lineup of quality battery packs, that allow optimized recharging of USB-powered devices on the go. We have previously reviewed the Gum™, Gum Max™ and Gum Max Duo™ battery packs and today, we’ll go hands on with the medium-sized Gum++ (double plus).

The reason why I refer to the Gum++ as a medium-sized battery pack is because it falls right in between the smaller 2200 mAh Gum and the larger 11,200 mAh Gum Max Duo, with just the correct balance of size, weight and recharging power. Clad in a glossy, hard-wearing shell, the 6000mAh Gum++ weighs half of what its larger sibling does, and packs almost three times the charging power of the smaller one.

Opening the traditional Just Mobile black box reveals the Gum++ battery pack, a micro-USB to USB charging cable and the usual documentation. Unlike other Gum series battery packs, Just Mobile has not included a carrying pouch with this one. Once again, the design is minimal and build quality is excellent which feels pretty solid when held in your hand. Five LED’s on top of the battery pack light up with a small push-in button, telling you how much juice is remaining.

With its 2.5A output, the charging times for all iOS devices are pretty quick. And since the input is also rated at 5V-2.5A, it replenishes pretty fast as well, especially when charged using the iPad Air charger. I was delighted to get 3x full iPhone 5S charges out of a single Gum++ charge, with still some juice remaining in the battery pack. With a full Gum++, the iPad Air reached around 75% (from 10%) in almost 2 hours before the battery pack gave out.

I can’t find a reason not to recommend the Gum++ to anyone looking for a portable, light-weight yet powerful battery pack. You can grab it online for $79.95 at just-mobile.com.

We also have an extra Gum++ battery pack to giveaway. The winner will be chosen at random so make sure you’re following us on Twitter and Facebook, and keep an eye on your inbox for a surprise in the next couple of days. Good luck!
