If you're curious about how long the Penaover 10000mAh Portable Charger holds a charge, there are a few things to keep in mind. The manufacturer mentions it has a 10000mAh capacity, which generally means it can charge most smartphones about 2-3 times before it needs recharging.

However, the actual duration can vary based on factors like how many devices you're charging at once, their power needs, and even the environment where you store and use it. Our research shows most people are pretty satisfied with its battery life for everyday use and travel.

It's super handy that it has a built-in wall plug and cables, so you don't need a bunch of extra accessories. This is especially appreciated by travelers.

Just a heads up, though: the built-in USB-C cable might not always support fast charging for every device. You might have to use your own fast-charging cable depending on what you need.

Overall, it's a solid portable charger that's especially good for traveling light.
