Battery Life
The Torpedo 2600 scored worst-in-class for battery life among small-size chargers, surviving delivering only 32 minutes of power in our intensive, ‘real world’ tests. By comparison, this is only 33% of the battery life of the iHome PowerClip 2600, and 25% of the battery life of the Outdoor Tech Kodiak Mini, both of which sport an identical 2600 mAh rating. Discharge rates are on par with industry averages among competitive devices.

Power/Size
Because of its low overall battery life, the Torpedo 2600 places last among small-size competitors for power per cubic inch, and power per ounce.

Durability
What Brunton’s Torpedo lacks in power, it makes up for in durability. The majority of the device is constructed from the highest-grade, most rugged aluminum or alloy we’ve seen among any device. The weakest parts of the device appear to be toward the car charger, which use are separate pieces and use thinner metal and high-density plastic cap near the end. This could also provide an opportunity for water or moisture to intrude. The end of the Torpedo also flexes somewhat under torsion, but this may be by design and may actually help absorb shock/force, as the Torpedo passed our drop and impact tests with flying colors.

Features
The Torpedo 2600 comes with a 1 amp charging USB port and a power level indicator, and is the only cylinder shaped charger to include a car charger. The durability of the Torpedo may also suffice as a hammer to break a car window in the event of an auto emergency, though the device was not marketed as such.

Value
In terms of cost and battery life per dollar spent, the Torpedo 2600 is last among all small-size chargers tested. But these scores are offset but the Torpedo’s outstanding durability and utility.
