While solar battery banks are one of the most popular methods for charging small devices in the outdoor and off-grid setting, it struggles in two major areas: charging time and consistency.

Portable solar batteries have a notoriously slow charging time, often taking many hours to reach full charge capacity. And the sun itself isn’t always available on cloudy days or at night.

What if there were a way to utilize a more abundant resource for energy. A resource as abundant as, perhaps, twigs, leaves, and wood?

The Biolite Campstove 2 is an ultra-popular, off-grid device that does just that: turns organic fuel into usable energy.

By continuously burning twigs, wood, leaves, or any combustible organic material you may find in the outdoor setting, you can potentially have an endless source of energy for charging your small devices.

This is my review of the Biolite Campstove 2.

How Does it Work?

The Biolite Campstove 2 generates energy by burning organic material such as wood, twigs, and leaves. Through its patented combustion technology, a vortex of smokeless flames rises from the stove and can be used to cook meals and boil water. The heat generated from the flames powers the attached powerpack which can be used to charge small devices such as phones, flashlights, and cameras.

Biolite's patented technology captures excess heat from the stove through a heat probe attached to the powerpack. This heat is converted into electricity through a thermoelectric generator, storing the energy into the powerpack to be used to charge external devices via USB cable.

The internal fan allows for the elimination of smoke and for controlling the distribution of heat toward the thermoelectric generator, providing a safe and controlled environment.

The Biolite Campstove 2 in Action

The Biolite Campstove 2 essential has two functions: it can act as a portable stove for cooking and can charge small devices with its powerpack.  Powerbanks that rely on other external energy sources such as solar are dependent on the weather conditions and aren't consistently available for power. The Biolite Campstove 2 works great as an additional power source and can potentially provide unlimited energy provided there are fuel sources nearby. The Biolite can even be used to recharge your primary solar powerbank whenever sun conditions aren't quite optimum.

While the combustion chamber is small and might require frequent feeding of fuel, the stove itself burns quite well as it allows for great circulation, providing a strong, consistent flame.


At 2 lbs and 5" x 8" in packed size, the Biolite Campstove 2 can easily fit into a 32 oz canister holder and carried along in a pack. Its light weight and compact size make it easy to carry on long hikes and don't take up much space.

Charging Times

With the stove burning, it can take about an hour to charge the battery to about 50% capacity. At 3 watts, the battery can sufficiently charge small devices to capacity before needing to be refueled. An LED light on the side of the powerpack indicates the power level.

Is it safe?

Some customers have voiced concern over the danger of having a battery as part of a stove. The design of the Biolite 2 intentionally keeps the battery away from the flame and the internal fans regulate the heat absorbed by the thermoelectric generator. The Biolite Campstove 2 is very safe and has undergone rigorous testing.

User Reviews

The stove is very easy to use, I love it!
I got some pellets from the hardware store and they work great! I'm a car camper (so weight isn't an issue) and wanted something small and quick to heat water for tea/coffee and dehydrated meals. The light is useful and the power port is nice to have.
