Whether you need to charge your phone or laptop when traveling or power up a fan and rechargeable lights on a camping trip, having a portable power bank handy is a must. Especially when spending time in the great outdoors, you need a power source with ample battery life that holds up in the elements. That's exactly where the rugged design of this Kapurui portable solar power bank shines.

Normally priced at $50, the Kapurui Solar Power Bank is now available at Amazon for just $30 — a 40% discount that saves you $20 and time spent chasing down a charger port to plug into when your phone dies. Shoppers love the waterproof design of this lightweight device because it can charge up to two devices simultaneously and has a high-powered flashlight that one reviewer called "crazy bright." Now, getting caught in a midnight rainstorm or trekking across a river won't stop you from using your devices.

The 36,800 milliampere-hour battery is meant to last up to 100 hours, which can charge a phone multiple times. The power bank also has solar-charging capabilities, so simply pop the panel into the sunlight whenever you need more power, a feature users love for emergency situations. Dual USB ports with Quick Charge 3.0 fast charging (5 volt/3.1 Amp) let you power two devices simultaneously. It's also got a built-in compass, making it “a lifesaver for outdoor trips.” With this deal, you’re getting a versatile, high-capacity charger at a fraction of the cost.

"Love these so much. I use mine all the time," one shopper said. "I got one for everybody for Christmas. Everyone was so happy, especially the campers in the family. I always keep mine charged. I can get about 10, maybe more, full phone charges out of one full solar charger. This is so worth having if there are multiple people around or if you are outside.

While some users mention that solar charging is slow (best used as a backup rather than a primary charging method), the USB charging is fast and reliable, making this a standout pick for emergency prep and outdoor activities like hiking, camping, or attending festivals. At just $30, down from $50 at Amazon, the Kapurui Solar Power Bank is a smart purchase that will keep you well-lit and powered up on the go.
