Died in 3 months and no support.
I bought it in September 2022. It stopped working in November. Does not accept the charge anymore.
The support told me they could not find the serial number printed on the unit and the packaging, so they are unable to identify the device and could not help. So the 1-year warranty does not exist.
It is too late to return it either.

Great device
Great for external power for any device. Weight is decent given how many charges it can provide.

Nice design and space conscious
How they tug the cables and make everything so well contained is impressive. It's 20000mAh capacit is also impressive

Works great! 10/10 would buy again
Charges Lenovo Thinkpad T14, phones, wireless earbuds, etc with no issues. Built-in type C cable is really handy. Perfect for my needs. Would recommend to anyone looking for a portable battery that's capable of charging laptops

Very nice capacity - needs optional though.
Only used a couple times, but seems to have a substantial capacity - charged my laptop and didn't drop more than 2 bars of power. Does take a bit to charge though, so would be better if it came with it's own charger - designed for it.

Great power banks
We have 2 of these 20,000 mah power banks as they are really useful and my wife and I have a lot of portable devices to keep charged. They have a rapid charge time and a variety of sockets to use.

Great Product, Even better customer service!
Great product for charging laptop when low on power. Light, Compact, charges quickly. convenient that it has the usb C built in. also great that Lenovo is on top of any recalls and reached out when there was an issue saying they would replace it even after it was out of warranty. Highly recommend Lenovo's products. service, quality, customer support, all great!

Very light for the size and capacity
Bought this as a gift so haven't opened nor tested it. One thing I can tell you is that the Lenovo USB-C laptop power bank is lighter than my current 20000 mAh power bank that I bought from Amazon.

Lots of Power
Great portable power pack. Will power your computer just like it was pluged into a regular 110W power source. Lasts quite a while too. Bought it on sale so that was an extra plus. Highly recommended.

So far so good!
I like the flexibility of having a built-in USB-C cable, a USB-C port and a USB-A port. The built in cable is longer than it looks because it unwraps from almost all the way around the battery. It snaps back into place very easily too.
