It never hurts to have a little extra power. It definitely hurts to have that little extra power in the form of some bulky, heavy device that weighs down your backpack or is too big for a pocket. RAVPower's device manages to fit 10000mAh in a portable charger small enough to carry anywhere. It's only 15mm thick and weighs less than eight ounces. Wherever you need that extra juice, take the RAVPower with you.

Obviously you can find power banks with a lot more output, but 10000mAh is plenty for any journey. You can completely recharge an iPhone 11 Pro Max one and a half times or a Samsung Galaxy S10 twice. If you have a smaller phone than either of those, you can get even more out of it. The product page lists a lot of the compatible smartphones, but suffice it to say this charger can be used with pretty much any iPhone or Android phone, including the major ones and lesser known models.

The two USB-A ports can be used at the same time. They use iSmart tech so they can detect what's being plugged in and deliver the best possible charge. There are also built-in safety features that keep the power bank from over charging or doing other things like overheating or short circuiting. All your devices will be safe while plugged in.

RAVPower backs this power bank up with an 18-month warranty.
