Power banks are handy devices that will keep electronics running when you don’t have access to a power outlet. These devices are a key component of off-grid survival gear, and they vary in size and capability. Power banks will range from pocket-size devices that can charge a phone or GPS, up to large, high-capacity power banks that can run non-rechargeable equipment, like a CPAP or a small refrigerator. 

The power banks I chose here are easy to pack and carry and are geared mostly for smaller electronics. If you’re looking to run a fridge or TV, you’ll need to upgrade to a large unit.

  • Integrated safety circuitry

This is the best portable power bank because it not only offers standard USB charging, but also has a 12 volt car charging socket and an AC outlet.

I’ve been camping for years, and in that time, I’ve had many different experiences with several different power banks. These have given me insight into the best features of a good power bank.

When researching my picks, I combed through several dozen manufacturers and models on multiple platforms, read through reviews, and applied my own first-hand experience to determine what works best in real-world applications. Reliability and versatility are the primary focuses of my picks, and below are other key factors that went into my recommendations.

  • Size and weight: Will it fit in your bag or backpack, and how much weight will it add to your pack?
  • Capacity: How much power will it hold? This determines how long it can power a device and/or recharge other things.
  • Output type: What type of USB ports does it have, and now many? What’s the amp output for them?


Q: What is a power bank?

A power bank is a device that will charge any battery-operated electronics. They come in all different shapes and sizes. Users should consider their priorities before purchasing a power bank to determine what features will serve them best. 

Q: How does a power bank work? 

A power bank works by being charged from a power source, whether it be an outlet, solar panel, or car. Once charged, the power bank can serve to recharge different electronics, often on the go or in remote places where electricity isn’t accessible. 

Q: How long does a power bank take to charge?

Every power bank is different, and there is no one set amount of time it will take to charge. Size, battery capacity, and brand are just a few of the factors that determine how long a power bank will take to charge. It is a good rule of thumb to prepare and allow for plenty of time to charge your power bank before heading on your adventure, if possible. 

Final Thoughts on the Best Power Banks

There’s no magic bullet for choosing the best power bank. Looking strictly at capacity doesn’t tell you the whole story. If you need to charge multiple devices, look for more output ports. If size is a consideration, pay attention to the weight and dimensions. The most important thing is to carefully consider your essential gear and what you need to get out of a power bank.
