charmast 20000mAh Portable Charger with Built in Cables 22 5W Travel Power Bank Fast Charging USB C Cell

These chargers are fantastic. We've bought several because our sons keep stealing them and we travel a good bit. They are a bit slow to charge - I'd recommend leaving them on overnight. But they charge other devices faster than any other charger I know, and the built-in cords are incredibly handy. At this point, most of our devices are USB-C, but then we will have that one random Lightning cable device, and that one random device with a kindle port. This has made my "emergency chord drawer" obsolete. Highly recommend. Read more

This 20,000 mAh power bank is excellent. It charges my phone multiple times without any issues and holds a strong, long-lasting charge. The size is reasonable for the capacity, and it’s perfect for travel, work, or emergencies. Very reliable and great value for the price. Read more

The power bank arrived securely packaged and looks great. It feels sturdy, charges devices quickly, and the battery lasts as advertised. Overall, a reliable and high-quality product. Read more

We grabbed this Charmast portable charger because someone in our family always seems to hit 5 percent battery at the worst possible time. This thing has already earned its place in the backpack. The built in cables are super handy. I don’t have to hunt around for a charging cord or worry about forgetting one at home. You just plug in and go. It holds a ton of power. We’ve gotten multiple (2-3) full charges out of it before needing to plug the charger back in, which has been great for travel days and long outings. It is a little heavier than the tiny pocket sized chargers, but that makes sense with how much capacity it has. I’d rather carry a little extra weight and know I am not scrambling for an outlet. It charges phones and tablets at a good speed, not instant, but definitely faster than those older cheap battery packs. The built quality feels solid too. Nothing flimsy or rattly. Overall, this has become our go to backup battery for trips, kids’ activities, and just everyday life when batteries run low at the wrong time. We bought 4 of them one for each person in our family and it they have all been working great for the past few weeks. Read more

I actually bought it twice. Charges your device up 4 times. It comes with all the cords you may need. The USB is included as well and charges with the use of a brick or USB port. The unit does take quite some time to fully charge, but holds that charge well. It's about the same size as my Samsung Galaxy. Read more

This is possibly, no, this IS one of my best Amazon buys. This thing lasts so long. I can get around 4-6 80% charges on my phone for the battery-pack. It also charges fairly fast, i just leave it to charge over night. This thing also charges things so fast, i prefer to charge my phone using this than a cord. I personally have really made good use of this charger and strongly believe that if you are looking for a portable battery pack then you SHOULD buy this one. Also the size is perfect, i can have my phone plugged into it and be able to fit both into my pocket (it does look a little weird when i do it tho). I havnt tried other battery packs but again, you would not be disappointed if you were to buy this one. Read more

It's perfect for I wanted. LOVE the built in cables !! Powers iPhones FAST and doesn't take much usage. Mac computer takes a while and drains a lot of the battery. The recharge is SLOW. But the size and price make up for any negatives My wife has bought one after I showed her mine Read more

I bought this charger in Dec 2024, it was fast charging and able to charge iPad Pro more than once but now, Nov 2025 not even a year, it does not work properly. it can’t even fully charge the iPad Pro which still has 40% power left. Read more
