Portable Charger Power Bank 30,800mAh LCD Display Power Bank,25W PD Fast Charging +QC 4.0 Quick Phone Charging Power Bank Tri-Outputs Battery Pack Compatible with iPhone,Android etc(Black)ClimatePartner certified

This is a good charger. Upon first receiving it, it took awhile to charge but after it charged, it charged my cell phone in a decent amount of time. I used it several times when the electricity went out for several hours at my house. The chargers charge stayed charged for a long time.

Since we have a few rechargeable lights, the last time our power went out I bought a few charging power banks to be more prepared for the next time we lose electricity. Of the power banks I bought this is my favorite. If the power runs out on this power bank, it does take a good 6 hours to recharge it. Since it holds 30,800mAh of power, this is to be expected.Most recently, we lost our internet service due to technical problems and the prospect of correcting the problem could not be determined since they had to replace cables on a roof that was covered with snow. Fortunately, out mobile service offers unlimited bandwidth to cast to our TV from a tablet or phone. I have a Samsung Galaxy S7 that can use mobile data on my phone plan, but hadn't used it in a while and the battery was dead. I connected this tablet to this power bank, and within a couple of minutes had enough power to power on the tablet. This power bank not only completely charged the tablet, but kept it running all night so we could cast programming to our TV. Since my husband and I are both night owls, this amount to about 7 hours this power bank kept the tablet running. After this time, the power bank still had 40% of its charge left. Most of the other power banks would have been drained long before we went to bed.Although some reviewers have reported problems with the charging cable staying connected, I have not experienced this problem. Whether charging the unit or using it, I love that the press of a button shows the percentage of charge in the power bank. Considering the size and weight of this power bank, it's not something I would carry in my purse, but would be excellent for travel if transported in luggage.For my purposes, it has been an excellent source of power for my tablet, and I keep it charged for times we need it to power lighting when the electricity goes out. When stored and not in use, it holds the charge where other power banks I have lose the charge during storage. Overall, I would definitely recommend this power bank.I hope this review was helpful for you.

What does power bank! Charges quickly, lightweight gray for my travel. HOWEVER it has a two year warranty with the manufacturer. I have two months left of my warranty and it has stopped charging. No way to get in touch with the manufacturer or the seller. All Amazon could do is offer me $10. Not a very happy customer!

Edit: 10-22-24 raised from 1 to 4 stars. After I found the right charger for this, it charges up quickly and holds a good charge. It also charges my Pixel 7 quickly. It is NOT 30,800, but it's still a nice unit for the dough.The power bank looks and feels impressive. To get it to 100% from the 52% it arrived at took over 9 hours. Then I charged up my Pixel 7 from 48% to 100% and it ate up 21% of the power banks available power. It did charge the Pixel up in a decent amount of time, but there's no way this has nearly the power they claim.I'm going to test it out for another week. If it doesn't get faster on charging the power bank up with a better cable, it's going back. The included cable is serious junk and woefully short. The "C" portion of the power bank seems to fight the cable going in and when taking it out. Not happy, but willing to test it out for another week before throwing the towel in. I blindly ordered a second one which I was lucky enough to cancel on Amazon. Great, fast, and reliable shipping from Amazon.

My carryon luggage has the ability to charge devices and I purchased this charger for that purpose. The charger fits nicely in the luggage and works like a charm. Long charging time allows me to watch movies on my phone and stay charged. Must have device!

I love this charger! It changes quickly. The battery last forever. It is very durable. This is my go to charger. Super easy to use. The size is large. It has alot of power.

it charges your phone INCREDIBLY FAST!!!!! love love love ! charging power is through the roof, great quality, not small but not giant either....a bit heavy but totally worth it.
