Charmast 20000mAh Power Bank with 4 Built-in Cables, 22.5W Fast Portable Charger for iPhone, Android, iPad, No Extra Cords Needed for Travel, Work, Emergency

This is one of my favourite power banks. I love that all the cables are attached, so I don’t need to worry about fiddling around or carrying extra cords, it’s super convenient and hassle-free. It’s really powerful, and once fully charged it lasts a long time, easily getting me through multiple charges. It’s a bit on the bulky side, but honestly I don’t mind because the performance and convenience more than make up for it. Overall, a great power bank that I’d happily recommend.

This portable battery is an ideal size: it's about as large a capacity as you can take on to an aeroplane, but physically is a nice size and a shape that would slip into a pocket or bag very nicely. It has a reassuring (but not back breaking) weight, it feels solid and well constructed. The Charmast displays battery charge as a percentage which is much better than the 3-4 little winking lights many other batteries have. The display is located under the surface of the battery case, which is cool. It also has a little green symbol which lights up when quick charge is engaged. The battery uses USB-C for fast charging up. It has two charging USB-A outputs and one quicker charge USB-A socket (colour coded for easy of recognition). You can also quick charge a device via the USB-C socket. This means you can a total of four devices on charge at once! If you charge multiple items you lose the ability to quick charge, but this is a reasonable tradeoff for being able to charge four devices at once (I'm doing this now with a phone, a tablet, a digital camera and a pair of headphones, and it's working flawlessly). There are safety circuits to prevent overheating (the battery did not appear to warm up noticeably while working) and also turns off charging when you devices are full. Battery life seems to be about right for the stated capacity, but I will wait to see how it beds in over repeated cycles. All in all this a a fabulous piece of kit for a very reasonable price, especially when its on offer via Amazon. Recommended!

This is a truly brilliant device. I bought the higher capacity one and am so pleased I did. It’s a manageable weight and seems to last forever! No loss of charge if not used and will fill an iPhone several times over - useful if you are taking loads of photos and using the battery up more quickly than usual. It’s incredibly quick to charge and the convenience of not needing separate leads is huge (it’s yet to be seen how well the built in leads last). I can walk around using my phone as it charges if needs be. Or sit over a coffee while it slurps up the juice for its battery. My daughter snaffled mine when visiting her far away so on return home I immediately bought myself another. I wouldn’t go anywhere without it now.

Not as good as Anker, seems to lose power over time, but a lot cheaper. Will definitely last a few years

Absolutely love this power bank! The 23800mAh capacity keeps my smartphone and tablet fully charged multiple times, and the Quick Charge 3.0 & PD 20W feature charges devices super fast. The LED display is really handy to see the exact battery level at a glance. It’s compact, durable, and works perfectly with all my devices. Perfect for travel, work, or daily use — a must-have portable charger! ✅ Massive 23800mAh capacity ✅ Fast charging with Quick Charge 3.0 & PD 20W ✅ LED display for battery level ✅ Portable, reliable, and compatible with multiple devices Highly recommend — a high-capacity, fast, and dependable power bank!

Not to heavy and can use phone while recharging Six charges from 40% per full powerbank charge and powerbank takes quite a long time to recharge I just do this overnight Very useful having all the wires attached

Very good power bank. Seems well made. Gets rid of need to carry multiple cables. It’s fairly slow to charge itself but it charges devices plugged into it quickly. Only thing that would make it better is if you could charge the power bank and use it charge devices at the same time but that functionality is not supported.

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!

ممتاز و سرعه الشحن جيده

Excellent, excellent et encore excellent ! J'adore cette batterie. Pour quelques explications, elle se charge assez lentement, j'en convient mais elle charge environ 3 portables voire un petit peu plus pour d'autres articles telles liseuse.. Les câbles sont certes petits, ce qui est logique, mais hyper pratiques. J'ai acheté 1 autre batterie comme celle-ci tellement j'en suis satisfait

Muito bom. Tem grande capacidade e ter os cabos incorporados dá muito jeito.

Ich hatte den für eine Reise geholt und bin sehr froh darüber. Die ist wirklich praktisch für unterwegs, ich finde es toll, dass die Bowerbank bereits verschiedene Akkukabel dran hat. Dadurch muss man nicht extra die Kabel einpacken, sondern nur die Bowerbank.
