The Brunton Torpedo 2800 came in a blister pack and cardboard. A user guide, printed in multiple languages, is located under the product inside the packaging. The Torpedo is cigar-shaped with a silver-tipped car adapter on one end and a black metal enclosure on the other end.

The Torpedo feels heavy in my hand, in part due to the metal enclosure and also the battery encased inside.


There is one micro USB port, used for charging the Torpedo, located alongside a standard USB port, used for recharging other devices. On the opposite side of the micro USB port is another standard USB port. Next to the USB port is a button and three LED indicator lights.


According to the manual, each standard USB port outputs 1 AMP of charge, so two devices can be charged simultaneously.

When the button is pushed, the LED lights indicate the charge remaining in the Torpedo: 3 dots= 100%; 2 dots = 60%; 1 dot = 30%.


The Torpedo contains "high-grade Lithium ION cells" that boast a faster charge and longer lasting charge with "no memory and minimal discharge," with "1,000 cycles at 80% capacity."



One of the first things I did after opening the package was to plug the Torpedo into my car. The LED lights immediately began blinking, once the car was turned on.


The Brunton warranty is very generous, and very simple: "Buy it. Try it. Bust it. Return it. No questions asked."

I've been able to attempt recharging a few devices already. With the Torpedo fully charged, I plugged in my iPhone, which was hovering around 30% battery capacity, and filled it to 100% capacity. I next plugged in my iPad Mini. The iPad Mini was at 15% capacity and the Torpedo emptied out but was able to get the Mini to 30% capacity.

I charged the Torpedo again and used it in a following day to recharge my iPhone, which was at 4%. I was able to charge my iPhone from 4% to 100% but it drained the Torpedo to 30% (1 LED indicator light). I was surprised, and a little disappointed, because how low the Torpedo drained after one complete recharging.


I really like the idea of having a recharging battery device that I can plug directly into my car. This way, when I travel out to a backpacking trip, I can keep the battery topped off and have it ready when I hit the trail.

I'm a little worried about if it will live up to the claim of recharging my smart phone two times under a full charge. It also feels a little heavy for how much capacity it has. It is certainly rough and rugged, but I'd almost prefer a lighter casing for more battery capacity.

PRO—Car charging option.

CON—On the heavy side for the capacity.

I would like to thank Brunton and for providing me with the opportunity to test this product.
