BigBlue 28W USB Solar Charger

BigBlue 28W USB Solar Charger

The best portable solar charger

This lightweight solar charger gives you the most usable power for the size. Plus, it has three output ports to charge more devices than the competition can at the same time.

Buying Options

$60 from Amazon

The BigBlue 28W USB Solar Charger produces the most power of any portable solar charger we’ve tested, and it has unique features that make it more versatile and durable, including three output ports (versus two on most other chargers), a weatherproof port protector, and an expansive but lightweight array of panels to catch every last ray of sunlight. Although other models come close to matching it in terms of power, the BigBlue is also smaller and lighter than other options with similar output, so it can more easily fit into a camping backpack, hiking daypack, or emergency kit.

Runner-up

X-Dragon 20W SunPower Solar Charger

X-Dragon 20W SunPower Solar Charger

Similar power, fewer features

If you can’t get our pick, this model is about the same size and almost as powerful but equipped with fewer ports and panels.

$55 from Amazon

If the BigBlue is unavailable, we also like the X-Dragon 20W SunPower Solar Charger. In testing, it was second only to our top pick in terms of how much power it produced throughout the day, and it even produced a little more when the sun was at its peak midday. While this model will charge up your devices just as fast as our top pick, the X-Dragon lacks the convenient extras—such as the additional charging port and the port protector—that make the BigBlue stand out.
