    For the price, this is a must have. I use this all the time to charge my drone batteries while out shooting. Also used a few times to recharge my phone and iPad while on the road.

    Perfect for on the go, especially using public transportation or not wanting to sit inside a coffee shop/fast food & search for wall outlets. Does take a bit to charge.

    Love my Power Bank. I've always purchased Energizer power bank. They last longer and no problems. It's heavy, but i will not carry it with me when i'm out.

    This is a great power bank. It can be a little heavy but you can recharge your phone and a table multiple times. We took it on 4 day/night train vacation and at the end still had a good percentage left on the power bank.

    While still sizeable, this portable charger has a lot of capacity in a smaller footprint than a 20k mah battery I have from ~6 years ago. I'd recommend.

    I cant even beging to tell you how long this charger lasts. Its take a half day to charge but it will last you 2-4 days of battery life if you are looking for an outdoor charger for your electronic devices! No need to worry about it losing charge fast and it was the best purchase ive made so far

    I boguth this bank based off of it already being charged and ready to go. The car I rented had a USB port that died. I couldn’t risk my phone dying as i traveled three hours to a town I’ve never been to. This one was the only one with this big of a battery AND charged. I opened it and it was at 80% and enough for my trip. While it doesnt charge quickly back to 100 after using it to 69%, its expected and shows its going to last several charges. A full day out on the town doesnt scare me as long as I have this bank. Well priced too!
