Three alternative ways to charge your phone

Power outages or off-grid adventures shouldn't leave you with a dead phone. Here are three ingenious ways to charge your device using readily available resources. While charging speeds vary, these methods ensure you stay connected, even on a desert island!

1. Harnessing the Sun's Power:

Weighing less than 1.5 pounds, the compact RavPower 16-watt solar charger efficiently converts sunlight into usable energy. Its three panels boast approximately 22 percent efficiency. Two USB ports allow simultaneous charging of your phone and a portable power bank, offering charging speeds comparable to a standard wall outlet (though slightly slower).

2. Fire-Powered Charging:

The BioLite CampStove 2 transforms the heat from a fire into electricity. Its innovative design uses a fan to intensify the flames, and a thermoelectric generator converts this heat energy into 3 watts of power, delivered via a USB port. Charging is roughly half the speed of a home outlet, with excess energy stored in the stove's built-in 2,600 mAh battery.

3. Manual Charging with a Crank:

The Goal Zero Lighthouse 400 lantern features a 4,400 mAh battery, providing up to 48 hours of LED light or a full phone charge. When the battery depletes, simply crank the top at approximately 130 rotations per minute for over 10 hours to fully recharge your phone. (Consider this a workout for your arms as well!)
