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

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!

Excellent portable battery, the charge lasts a long time and it perfectly charges everything that is connected to it. It's a little heavy but very resistant. I highly recommend it for long trips.

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.

So I bought this because I love my phone but the battery life isn't great. But who wants to be tied to a wall charger? Not me.. this works perfect to prevent me from having to deal with that. It has a standard charging port as well as a c charging port to charge the device itself. It also has 2 USB ports so you can charge 2 devices at once.I love this device for several reasons. The 1st being it has a digital display which allows me to see the chargers power level. I can tell how much of a charge I have before I leave the house so I don't have to guess and end up with a 20% charged device but needed more. 2nd reason is that it can charge up to 100% in a matter of about 2 hours. That's fast! It doesn't use up the power fast either. I can charge my phone from about 15% to 70% in about 20 minutes (30 if I'm playing a game) yet the power bank has only used about 25% of its supply. That's amazing!3rd reason is because I can charge 2 devices at once and still have at least 35-40% juice in the bank.In conclusion, I definitely recommend this power bank. It's probably the best one for the price on the market right now.*on a side note:This is probably the 4th or 5th power bank I've bought (not this brand) but they were all very disappointing. They either took too long to charge (the device itself) and went dead too quickly or they took too long to charge devices

My favorite power bank. I've gifted several of these because they're durable, inexpensive and can fully charge your device multiple times. Has not failed me yet and I've owned one for a couple of years. We'll worth the price.

I was not happy about how slow this thing charges. But once you use it to charge your phone, its super fast and only take 20% for a full charge.
