The 10 Best Solar Charger Power Bank for Backpacking Reviewed
1. Solar Charger Power Bank 49800mah Wireless Portable Phone Charger, 22.5w
We put this hefty 49800mAh solar charger through its paces on a recent multi-day hike, and it certainly delivered on capacity. The wireless charging feature was a convenient addition, allowing us to top up our phones without fumbling for cables in the dim tent light. Its robust build felt reassuringly durable, ready to withstand the bumps and scrapes of trail life. However, the sheer size and weight of this unit are considerable, making it a less-than-ideal companion for ultralight backpackers.
Charging speeds were respectable, especially when plugged directly into a wall outlet before hitting the trail.

Its rugged design and ostensibly durable casing suggest it can withstand the rigors of the outdoors. The high capacity, advertised at a generous amount, promises extended power for multiple devices throughout a trip. We found the integrated LED flashlight to be surprisingly bright and useful for navigating camp after dark.
The solar panel, while present, is more of a supplementary feature than a primary charging solution. Expect it to add a small percentage of charge over many hours of direct sunlight, rather than fully replenishing the battery. The charging ports felt a bit stiff when plugging in cables, and the overall bulk of the unit made it take up a bit more space in our pack than anticipated.
This power bank is a good fit for backpackers who need a large capacity and appreciate the added security of a solar trickle charge, but who also have access to power sources periodically. It’s not the best choice for those who will be completely off-grid for extended periods and solely rely on the sun. Anyone prioritizing extreme portability might find its size a minor inconvenience.
Pros
- Large capacity for extended use.
- Rugged and durable construction.
