Portable-Charger-Power-Bank - 2 Pack 15000mAh Dual USB Power Bank Output 5V3.1A Fast Charging Portable Charger Compatible with Smartphones and All USB Devices

It's the size of my phone, so easy to carry. With a high speed cable will charge my dead phone to 100 in about 2 hours. It lasted 3 and change charges. It does take 6 hours to charge the battery fully, if you have a good cable and charger set up. Just keep that in mind before needing it.

These are good for the value. I had to return others because they all say airline safe but when I received the package, it’s marked “FORBIDDEN ON AIRCRAFT”.I ordered these and was able to take them on my trip. They charge fast and hold the charge well. They’re nice and portable and can easily slip in a purse or back pocket.

Pro: small (size of an iphone mini) & light weight, matt finish, hard case with 2 charging ports, holds charge well. Con: slow charging. Bought these when my family went on vacation. Use them as backup power for my Gopro and emergency charger for iphones & ipads. With both power banks fully charged, they have saved our phones many times as we constantly use our phones for directions and food search during the trip. These hold their charge well. After our trip, the power banks kept their charges for 4+ months (without needing recharge showing 4 lights). Tested a fully charged power bank by charging both an iphone 12 mini (at 37% power) and 9th Gen ipad (at 27% power) using both charging ports from one power bank at the same time. After about 2 hour 45 minutes, iphone mini reached 100% and ipad reached 56% with power bank having 2 lights left showing. Then unplug iphone and continue charging ipad. Ipad reached 70% when the power bank is fully drained (no lights showing). Then use the 2nd power bank to continue charge the ipad. About 2 hours later, the ipad reached 100% with the power bank having 3 lights left. Overall, these are good power banks to have at a reasonable price if you don't mind the slower charging.

This is the second one we've ordered in this brand. Haven't had a chance to try this one out, but should be fine. This brand usually last a very long time before we have to charge it. My teen son kept taking the first one. It will go in a jean's pocket, but it's not really practical for hauling around. It has a little weight to it. It gets used when he needs to charge his phone in the bathroom or we travel. The second one will get used to charge a small portable air conditioner.

These worked great. Charged them up, then kept them in my backpack throughout London. Kept the cell phone charged for my 1,000's of pictures.

So far so gd...charges my things fairly quickly and when on a stand by, back-up holds very gd longevity. But downside, when charging this unit when very low charge, like many others, it takes some time to be fully 100%charged. And that is using my rapid plug at 5v into it or is it just me? TBD...overall I am satisfied

Charges my phone and tablets and faster than a car charger. Portable and fits in my bag. Used these on trips and no one ended up with dead phones. Even phones at 5% were fully charged and still had power left in battery pack.

Has some weight to it, but I personally don't mind as long as it's well-made, performs, and will last. It's got all the ports you see and will charge 4 things at once - very slowly. Three stars bc there's two of them with two short cables, they technically work, the price was reasonable, and I'd use them in a pinch. I hate to say it, but I don't think I'd buy these again with all the affordable options out there.There's a button on the side that seems like it's only for checking the power capacity. You don't have to turn this unit on for it to charge a device. So the fact we can plug and go cool for us. Also we found that it will pass through power, meaning you can plug the battery pack into the wall and have it, and whatever is plugged into it, charging at the same time - very, very, Very slowly. But the features are there.It came charged with three lights showing out of four. It then took 6 hours directly plugged into a socket (with the usual brick adapter) before it reached a full charge. My phone took one hour to charge from 70% to 100% off of this battery pack, and that used up one light (3/4 of the battery), taking away another star from the review. Not close to the "fast" charging as was described by both description and some reviews, and testing it shows it will lot hold much of a charge. I tested both the black and white charger, and both gave the same performance results; too long to charge from the wall, and slow to charge a single device - my phone. The pack using 3/4 of the battery to charge a cell phone 30% is just not worth a second purchase.I don't yet know how many charges I'll get from the pack, but can update the review if it improves in performance. I bought this bc there were two of them, good reviews, and we needed something on a budget.Overall advice, I'd spend another $10 bux or so and get one that's been on the market longer, is a little lighter in weight, comes with a charging cord longer than a few inches, with the promise of fast charging kept, or a refund. Six hours charging for one light out of four is insane. My Bluetti portable power station (AC180, 1152Wh w/ 4 1800W (2700W Surge) AC Outlets) takes less time to charge, honestly, to be cheeky. To be fair, my other battery pack like these two here, it charges from halfway to full in less than an hour. I think it was $25.Hope this actual honest review helps someone :-) The pic of the battery pack that's all white/blank is just showing the texture of the unit, which does give it a stylist look, to end on a better note.
