When I first got this, it was charged to 75% already. Tested it and it worked great. Plugged it in and let it charge to 100% and then set it aside. I needed to use it the other day (weeks later) and it was still at 100%. Nice! It charged my iphone 50% in 20 minutes. That was enough at that time. The battery on the pack only went down 5%. Nice! Insert doing this 4 or so more times and the battery on the pack only went down to 67%. Nice! We're supposed to get storms today so I am charging it to 100% now. It takes a long time to charge. (At 67% had it plugged in for 1.5 hours and is only at 83% now.)

I just bought/received this charger after reading how unsafe it was to charge your phone/tablet at the airport outlets. I charged the charger to 100%, while letting my iPhone run down to 10%. It took three hours to charge my iPhone from 10% to 100%. After I charged my phone, I noted that it took down the charger to 83%. Not bad.

We took this to Disneyland, and it was amazing. We did 16 hour days, and this was awesome for charging our phones, fans, etc. I recharged it every night, but it honestly probably could have lasted all three days for us without needing it. It is also fast! It had my iPhone from 30% up to 90% in about 10 minutes. The built-in cords are amazing—everything you need is right there. This was the best purchase I made for our trip.

I am very happy with this charger. It works very well. It is a good size and a good value. It does take a bit to charge but I didn’t find that a negative. It holds the charge for a long time. I used it a lot on a recent vacation. The only negative for me is that is a bit heavy.

Glad to have made this purchase! The battery life lasts very long, fast charging, lightweight, and very portable(can fit a small shoulder bag purse)! I use this charger everyday! If my battery life on my phone is at 5% and leave it left alone to charge for 10mins, it’s already at 30-40%!! it does not only charge my phone, it can also charge nearly almost any electronic devices.

So far so good. It has charged both our OnePlus phones, (8t and 13r) with like 20-30% battery to full charge and it still has enough to probably charge them both again. It has charging cables built in and they work great. It may take time to charge it up from 0 to 100 but nowadays what doesn't. I like it better than my Anker 20000mah and it weighs less also. It's nice to see the power percentage display so we know how much is left.

The Charmast 20000mAh Portable Charger is a solid travel companion with its built-in cables and multiple outputs—no need to carry extra cords. It charges phones and tablets quickly, and the 20W output keeps devices powered up efficiently. The large battery capacity means fewer stops to recharge on the go. It’s a bit bulky for pockets but perfect for backpacks or travel bags. Overall, a reliable power bank that simplifies charging when traveling.
