I usually charge my Pixel 7 whenever it reaches 20% battery and this bank easily fully charges my phone to 100% and by then I have to charge the bank again. Im okay with that and that's exactly what I need it for. I leave the bank plugged in my phone while its in my pocket and have no trouble pulling it out if I need to. It's Super convenient and compact. It offers 22.5w charging, not the fastest but fast enough in my opinion. It was also an open box item so I saved a few dabloons there.

This battery backup is exactly what I wanted. It’s small so it doesn’t take up much space and it’s not heavy. It gives me the security I was looking for should my phone be low on charge while traveling. It only charges to 70%, but that’s really all I need as backup.

This little guy is pretty alright. Even though it is a 5,000 mah battery it will really only charge about 50-70%, but that’s sort of expected. It’s real purpose is to give juice to your phone in cases where a better power bank would be inconvenient to carry. That’s because it’s pretty tiny, being easily pocketable. If your looking to charge your phone at least a couple of times. Any 20,000 mah power bank should do the trick.

This little power bank is super convenient! The foldable USB-C plug means I don’t have to carry a cable, and it charges my phone fast for its size. Perfect for travel or daily carry when I just need a quick boost. Not meant for multiple full charges, but exactly what I wanted for a compact backup.”

Compact but can fully charge a phone on the go. I like that I can just throw it in my purse. And that I can still use my phone as it charges without too much extra weight

I purchased this for an upcoming trip mainly because it connects directly to my phone. The charge was quick but my phone and unit did get warm during charging. It comes with a USB type A to C cable--I suggest buying a C-to-C cable for a faster recharge of the unit.

Pretty good job charging overall. Can get a fully charged battery on iphone 15 pro max but it will drain most of the battery rendering the device useless after about an hour of use. Just remember to charge it after hsing it and its fine. Good for the price too!

I love this portable charger, first bought it during a power outage - it now lives in my purse. It's compact, fast charging no more panic that my phone is dead - and have no charging cable, etc. Excellent for train/subway travel charging, et.

A little inconvenient for my iPhone, but it works with an additional cord. Good to have in a pinch, but not a ton of charge on it, but enough.

The product itself will get 5 stars. It worked well and did the job.
The task of trying to register the product gets zero. The company makes it far to difficult to register as if they do not want you to do it. Finally got it completed after contacting customer service twice. They also wrote to me and said you cannot register it if it was bought as best buy and to sent them a receipt.

The best things about are that it's small, light, comes with usb-c flip-up nub, and can fully recharge a phone at least once from zero.
What it says on the tin. Gets you about 3 to 4 recharges for a Samsung A25, do your own math for your phone/device (google milliAmpere-hours). Could be better in a few ways, including some degree of waterproofing or the ability to pass-through data.
Get it if you want something that works, is unobtrusive, and wouldn't bother you too much to lose.

Bought this just to use occasionally on a cross country road trip and back. It worked great for my iPhone 16 Pro. Was able to get about 2 full charges out of it before it needed charged again itself. Its super light weight and compact. Super easy to slip in a pocket, fanny pack, purse, etc etc. Probably one of the best in this size category for portable chargers. Would definitely recommend.
