Last a long time. Make sure and charge it for the full recommended time in owner's manuL. Charges phones fast as a phone should be charged to ensure long lasting battery life on your phone. LED indicator is great to let you know battery life left in bank. ⭐️⭐️⭐️⭐️⭐️

Solid battery backup. I used it for a camping trip. Charged my phone from empty to full 3 times and didn't loose one bar on the charger. This is just what I needed for trips where there is low reception my phone battery dies quickly.

The power bank charges my devices very quickly. This power bank charged up very quickly. After charging it. I havd been able to charge my tablet, 2 phones and a few ear buds and there is still power in the bank.
This is the only time I used it.
Bought it for a trip znx I believe it will work great. It is a little heavy and the size of a small tab or large phone.

I had not had a larger power bank in some time, so I relied on my salesperson’s recommendations that met my criteria (USB-A, etc) The initial charging of this more powerful model took a very long time, but since then I have not needed to recharge it until today. I have charged my phone, my granddaughter’s phone, etc. several times with barely a dent in the charging capability l. If he were charging additional devices, it would still be very long lasting. Thank you, Ralph, for honing in on the power banks that would sit my needs best. Very happy with the purchase.

It works really well, however its huge! The initial charge takes about 6 hours so dont pull it out of the box thinking you can use it right away.
Its definitely one of those keep it in your backpack or on the desk while your phone charges.

Love having portable power whenever I need it and this keeps a long power life. The cord is easily adapted to work with USB or USBC which is convenient depending on which item you're charging.

I purchased this for my daughter to take on guard trips for school, and she loves it. It's reliable and reputable, and it fits my budget. It's a little heavier than I wanted it to be, but other than that, I am pleased with this purchase.
