What reviewers liked

The device is rated at IPX6 waterproof, meaning it can handle heavy downpour like a champ and still keep going. Small indicator lights show your battery life as well as if your solar panel is charging the battery. At 1.2 pounds, it’s on the heavier side compared to other smaller charges on our list, but that’s to be expected as its 2.5x the battery capacity of those as well.

The GoerTek ES982 is a powerful, 25000mAh solar power bank. It has a compact design, and only weighs a little more than a pound. In addition to recharging via solar, it can also be recharged via USB, like a standard power bank. It features a built-in carrying loop, along with a carabineer that allows it to be mounted just about anywhere. It even has a flashlight built-in, so it can serve multiple purposes.

Three USB ports are probably the best feature of this solar phone charger, which are powerful enough to charge three phones simultaneously. Your friends and family members can also charge their phones conveniently. There are two charging methods for this solar phone charger. You can use the 5V/2A adapter or solar. This USB power bank also hooks in 36LED lights to see outdoors when it is dark. The package comes with an included USB cable, carabiner, and a user guide manual to help you use the product seamlessly. The product weighs only 1.18 pounds, so it is much easier to carry from place to place.
