Great item. It's a powerhouse charger. A little heavier than a slim charger. It took many hours to recharge when I first received it because I used a low wattage charger. This item will recharge faster with a higher wattage wall charger. I'm beyond satisfied.

Great Power and Super Convenient

One of the best portable chargers I've owned. The size is compact and easy to carry, but it still has plenty of power. It charges my phone quickly, and the built-in cable makes it really convenient, no need to carry extras. We've even used it for our VR headset without any issues. I like it so much that this is my second one. Great value and very reliable….highly recommend!

If you don't have a newer iPhone (15 to 17, I think; it didn't fit my 14), you have to buy an extra cord, but it was ony $6 at Walmart, which was a little hassle figuring that out for me. The power bank is larger than my last one, but it still fits in my purse and tells you how much charge is remaining, so I like it.
