Battery Life
The AllTerrain 3000 offers excellent battery life, and survived for a full 184 minutes in our intensive, ‘real world’ tests — enough to tie for third-place among all small-size devices tested. Discharge rate is on par with industry averages.

Power/Size
The AllTerrain 3000 is actually the second largest of all devices in the ‘small’ size category. Though it offers less power per cubic inch than competitors, it is fairly lighweight, and its power:weight ratios are outstanding (second among all small-size chargers tested). 

Durability
Though both the myCharge AllTerrain 3000 and Outdoor Tech Kodiak Mini use a rubberized housing for impact protection, the AllTerrain differs by using a significantly thicker, high-density form of rubber. In addition, the interior shell appears to use stronger plastics. In tests, this translates to significantly higher scores and performance in impact, torsion, and compression tests.

The seal on the AllTerrain 3000 is also higher than the Kodiak Mini, which gives the All Terrain best-in-class water resistance for its size category. In the right conditions, the protective cap could open or be torn off completely inside a pack, though the tighter seal makes this much less likely than in competing devices. Cuts or slashes could also theoretically compromise water resistance, though the thicker rubber used by the AllTerrain 3000 also makes this less likely than with competition products.

Features
Aside from the durability/waterproofing features offered by the rubberized coating, the AllTerrain 3000 is a pretty bare-bones charger, offering a standard 1 amp charging USB port, a power level indicator, and a loop for securing the device to a pack.

Value
In terms of battery life and power per dollar spent, the AllTerrain 3000 scores average among small size chargers. It’s value, however, increases considerably when accounting for its best-in-class water resistance.
