A ADDTOP Power Bank Portable Charger - 26800mAh High Capacity 22.5W Fast Charging Power Bank 20W PD USB C External Battery Pack with 4 Outputs and LCD Display for Smartphone, Tablets Black

I just bought a second. This power bank lasts ages, charges my phone several times and can even power my macbook air slowly using USB-C PD.It charges the MacBook at 18W (9v, 2a I think) which is typically enough to increase charge while using. The only issue I find is that it will not charge the Mac if it has already run out of power. To do so you need to keep trying to get it to turn on to encourage the power bank to send charge. I reckon you could get around this by charging from one of the USB 2.0 ports, not the USB-C port. Anyway, not been an issue for me but something to be aware of.I bought a second as the battery on my first was losing capacity it seemed. However this is not unexpected. This power bank has been heavily used while traveling and camping in my campervan which has no leisure battery.Good buy!Adding to this review: I bought a second and experienced the same issue as other reviewers - the powerbank died at 30%, going straight to 0.I contacted the company and they immediately sent out a new powerbank to replace my faulty one. No trouble at all. These things happen and these guys offered fantastic customer service.Haven't tested out the new one yet, but if it's all good I might even buy a third!

Really really good powerbank. Highly recommended. I've tried many and this one tops it. The only improvement would be to have wires built in

Good quality, solid made, easy to use comes with cable to charge and link to iPhones etc. Does take a few hours to completely charge. Not to big will easily fir in hand luggage.

Really reliable item. Charged multiple items at once and easy to use. Perfect for flights (used on East Jet). Takes a long time to charge to 100% but also discharges slowly which is important. Comes with a short black lead to charge or discharge so I didn't even need to use my own mobile phone lead. Quite heavy. Used with Honor and Huawei phones but has multiple sized ports.

Very happy with this charger. It has charged reliably for almost a year and still going. Excellent quality and great digital display of the % charge.Had a problem with loose on/off button - reported to manufacturer. Addtop were first class in their service, replaced the faulty item very promptly and with no fuss. Delighted with Addtop and would highly recommend this charge pack, it is excellent.

The power pack stopped working after seven months. I reported the issue to the manufacturer who asked me to take a video of me testing the device with different chargers. I offered to return the item to them for their own testing and take a video if they didn't believe me as long as they paid the postage. I really don't have the time to set up taking a video.

Takes a while to fully charge, but, recharges phone at least 5 times. Best one I’ve ever had.

Useful device, but the instructions are minimalistic.The power button is unintuitive and not covered in the instructions. The device is powered on by a single click of the button or powers on automatically when a device is connected. To power it off, you need to double-click the button, or it will power off automatically after a short time if nothing is connected. If you press and hold the button (like powering off a phone or tablet), the state of charge display goes to a flashing 0% for some unknown reason, and the only way I've found to recover functionality is to connect the device to a charger.Will not do super fast charging on my Samsung phone; the best it does is fast charging.I affixed some small self-adhesive rubber feet to the back to stop it skidding about.
