Read the full portable power stations guide here. If you're planning to go off the grid or you're prepping for an emergency, we recommend the Goal Zero Yeti 1000. This portable power station—a giant battery with regular AC outlets on it—can keep your electronics charged and running for hours without the noise or exhaust that comes with a portable generator. After 35 hours testing five top contenders, we found that the Yeti's impressive capacity of about 1,000 watt-hours, easy-to-use interface, and rugged exterior stood out from the competition.

Having a portable power source is a must if you want to be properly prepared for your next glamping trip or just a long day in the park. EcoFlow's River Mobile Power Station is as near a panacea as they come, with a 116,000mAh battery, total output of 500W and 11 charging ports including USB, AC, DC and 12V. This smart charging station adjusts power output to match each device's wattage and even monitors temperature so devices won't get too hot. It holds a charge for about one year and can be topped up via a wall outlet, car jack or even using solar panels.
