I fell in love with portable chargers a few years ago. I have a large phone and I can go so back and forth to finish a work project that I found myself killing the battery and having to leave it to charge. I can keep this charger in my purse because it’s compact and charge my phone while I’m on the go. It can all just stay in my purse and no messy wires coming from my dashboard or from the outlet in the wall next to my bed.
With 10,000 mAh I can charge my powerful Note at least 3 times. It charges fast itself and I used the little cord they gave me. Usually those aren’t great but this one worked fine to charge the power bank but not to charge my phone. It’s quirky like that. My phone seems to be particular about which cords it uses.
