Portable power that does more

Goal Zero Sherpa 50 recharger

The Sherpa 50 can power smartphones, tablets, and even many laptops.

The ultra-portable Sherpa 50 recharger can power more types of devices, and for longer periods, than Goal Zero's more basic chargers. You can keep smartphones, tablets and even many laptops powered up when there isn't an AC plug in sight. The lightweight Sherpa 50 is easy to pack and carry, and can quickly be recharged from wall, car or sun.

What makes the Sherpa 50 so versatile is its substantial power storage capacity, and its ability to provide regulated power. Electronic devices like smartphones, tablets, and laptops are becoming increasingly finicky when it comes to charging. If they don't get just the right amount and consistency of power, they often won't take a charge — especially laptops. The Sherpa 50's USB and laptop ports supply regulated power to keep your gear happy.

The Sherpa 50 can keep several USB and 12-volt devices powered up when you're away from home. And when you are at home, it has enough juice to function as a limited source of emergency power during a blackout.

Goal Zero Sherpa 50 connections

Three ways to charge the Sherpa 50

There are three ways to keep the Sherpa 50 charged up and ready to go. If you don't have access to a conventional source of power, you can connect the Sherpa 50 to Goal Zero's Nomad 13 solar panel (a full recharge takes about 5 hours). Or, you can plug the Sherpa 50 into your car's 12-volt accessory port, or into an AC wall outlet — both of those options require about 3 hours to recharge.

If you plan to go solar and use the Sherpa 50 with the Nomad 13, consider the Sherpa 50 Solar Recharging Kit, which includes both products, as well as an AC inverter that attaches to the Sherpa and provides a standard 3-prong connector for powering AC devices.
