charmast 20000mAh Portable Charger with Built in Cables, 22.5W Travel Power Bank Fast Charging, USB C Cell Phone Battery Pack for iPhone 16/15/14/13/12/11 Series, iPad, Samsung, Android, Tablet

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.

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.

This was the best purchase for our trip. Taking long flights watching movies and listening to music take a toll on your battery. Plugging my phone in while watching two movies on a plane had no power loss when I needed to use my phone for directions. The charging rate is quick. The different colors made it easy to track for everyone in the family. Have different charging cables allowed me to charge iPhones, airbuds, and tracker device. Three planes out of 4 did not have charging options on my trip. Without this small light weight charger I would have been speaking with chatty Kathy next to me for hours. Worth it!!!

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.

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.

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.

Works great. Charges fast and charges attached devices fast. Love having the various cords built in and stored right on board. Small enough for travel.

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.

This power bank is very powerful and chages all you usb devices extremely fast. The built in cables with different usb connectors makes it very handy. The only inconvenience is that it is a little heavy but given the power it carries, I still have it with me everydsy in my bag. FIVE STARS!

Nice build quality good and working perfectly all wear

ممتاز و سرعه الشحن جيده

A life saver! I bring this with me everywhere and it’s perfect. It has the cords built in so you don’t need to bring cords with you and the battery life is good as well. I can charge my phone several times from 0% - 100% before the power bank is low and it charges your electronics very quickly. Yes the charge for the power bank itself is slow but that’s understandable since it holds so much battery life. It does have some weight to it but that’s also understandable since it’s a quality product. It does come with a sleeve to put the power bank inside. I would 100% recommend this power bank, I would definitely repurchase!

I bought this about 6 months ago and it’s still holding up well. I use it a lot especially when I am travelling. It is great to always have a backup battery on hand. Plus- charges fast, built in cables, still working well. Minus - wish it had a built in plugin attachment, a little heavier than my previous one I owned Overall, I’d recommend because it has held up better than other battery packs I have owned. All cables are still working well. No issues after a lot of use.
