CGTRADE Power Banks 20000mAh Portable Phone Charger Ultra Thin High Capacity Quick Charge External Battery Pack

Good power bank, don't think it's actually 20,000 mah it's probably 15,000 it charges about 1.5a I think but very slim and lightweight, works well for me as a permanent power bank in my bag.

Product is advertised to hold 20,000 mAh, but it will only charge my Samsung Galaxy S7 one and a half times. This is far less then my old charger, which held a lower charge, would do.It's build quality is great though, very small and stylish, it's a shame the charge isn't as advertised or it would be perfect.

It's so light and efficient! Has lights that goes down depending on what power it has left for charging. I use Google pixel 3a and it can charge it multiple times and did me well when having to spend 8 days working at a festival!

Like the size and how quickly it charged my phone. But the battery life is awful.

High quality. I'm so satisfied. Very light and so quickly for charging the phone.

It's definitley not 20,000mah. I charged my LG phone which has a 3000mah battery and the charger was indicating 25% charge left. I would say it has a 4000mah, maybe 5000 max. False advertisement so be warned.

Slimline, battery life lasted all weekend. Definitely a good buy!

Absolute waste of money. Bought it and attempted use it at two festivals this summer and both times it hasn't worked. I assumed I may not have charged it correctly the first time, so I ensured it was charged properly the second. Nope, it's just cheap, faulty and doesn't even work.
