onn 8,000 mAh dual USB-C/USB-A port portable battery, Black

I needed a battery bank to use as a backup power option for my cell phone and wireless earbuds. for $10 this power bank was a no-brainer. I can get at least a couple full charges for my phone and a few for my wireless earbuds. if this will never stops functioning, I will definitely not hesitate to buy the exact same one. it has a simple button to let me know how much charge is remaining, the moment that I see it has on LED turned on it lets me know that it is at 25% and that is when I start to fully charge. I can get a full charge in 3 or 4 hours which isn't bad especially being that it has overcharged protection built into it. I can connect devices that have a regular USB or also used USBC. the USB regular is output only but it works perfect and it serves its purpose

Was having cell phone charging issues! Was actually looking for a battery replacement for my cell phone and came across this product! This product actually "kick started" my cell phone to the point I did NOT need to buy a new phone! Now this Power Bank acts as an emergency power device when someone is in a rush or just forgot to charge their devices! You can keep it at home or bring it with you on the go! Can accommodate multi devices! To me a great buy and value for so little paid! Yes, I would recommend this product!

I had bought a device that needed USB connectivity to operate, which I could do with my computer. But then I discovered I needed it more for a mobile application and hauling my computer around was completely out of the question. After a little research, I found the highly rated onn 8,000 mAh dual USB-C/USB-A port portable battery. PERFECT! Completely portable ... all the power I need ... small package ... this was the answer to my problem AND at an incredibly affordable price. Win - win - win!

It's not awful me and my pawpaw actually both have one and it works pretty great it's not bad for 10 bucks although I don't recommend leaving it sit around off charge because it will die if it's not on charge unless you're using to charge your phone ofc you can't have it on charge but other then that's it's pretty good I recommend it personally

This bank is exactly what I was looking for. A good quality power bank with USB C for both charging the bank itself and for charging other devices. Previous banks from this brand used micro-USB, which I find to be very flimsy and unreliable. USB C is much more reliable and robust and that's why I sought it out. So far, it's holding up great and both charges devices and is charged faster than the outgoing model. Keep in mind you, you won't get a full 8000 mah of power out of this bank, both from inefficiencies in the charging process (totally normal and mostly lost as heat) as well as the bank being rated at it nominal voltage of 3.7 volts. It has to be "stepped up" with internal circuitry in order to charge your 5 volt devices, so the effective capacity is 4800mah.

I wanted a power Bank that was cheap, portable, and easy to use. The Onn 8k Mah power Bank definitely fits the bill. Great product for the price. I wouldn't necessarily classify it as a fast charger, though it gets the job done at a fairly decent speed. I've actually used my phone while having it plugged in to the power Bank, and it will even continue to increase battery percentage even as I stream movies and shows. It will fit in my pocket with my phone, though is kind of bulky to have in a front pocket while I walk. Definitely recommend, good value for the price, good battery life, easy to see remaining charge. cable that is included has been working fine for me.

Takes FOREVER to charge the battery pack, but it will charge your phone if you're out and about and realize your phone is dying. Just don't expect to use your phone while charging and it will take an incredibly long time to charge it.

I bought this because I thought it was a good deal, and if it worked for longer than six months, it would be. I took it camping a few times and it was great to have. But I am a private pilot, and I keep this in my flight bag to charge my iPad in case the battery gets low while I'm flying, because the iPad is an important tool for any pilot. Anyway, on a recent flight, I plugged my iPad in and nothing happened. I knew it couldn't be dead because I recharge it before every flight. But when I got home, I plugged it in overnight anyway, and sure enough, it's completely bricked. Won't light up at all. Not reliable, and an emergency backup battery needs to be only one thing: reliable. That's what I get for being a cheap rascal. Time to splurge on a more reliable brand.

I bought this for a GoPro, and for the GoPro to power on and record it has to have a certain voltage. An on the battery package it said it had that certain voltage which it didn't because my GoPro would even power on.

Stopped taking a charge within a week. Led indicator light only showed one light out of three after charging, then no light at all. Won't take a charge. Will be returning.
