Power bank that saves the day!

[This review was collected as part of a promotion.] I purchased both this product & dell’s version of the product. Ended up returning Dell’s. I’m a Dell guy, but Lenovo hit it out the ballpark with this product.
The usbc cord that comes attached to the battery is tucked in and out of the way, unlike Dell’s product that hangs out freely. This product only serves one purpose which is to charge other devices so something as little as that makes a difference for me. Lenovo kept their product tidy and sleek which is something I like. It keeps my phone charged up and it’s nice known I can give my laptop a boost for added hours of use. Lenovo also offers 2k more capacity than Dell for a cheaper price.
All around, Lenovo takes the trophy because they designed the product with the customer in mind. I didn’t even think the cord would be a deciding factor but Lenovo was on top of it with that one.
I would recommend this to a friend!

And, it's a perfect match for my Lenovo Storm Gray Yoga.

Great power bank with built-in USB-C cable

Verified Purchase:Yes
[This review was collected as part of a promotion.] I recently purchased the Lenovo Go USB-C Laptop Power Bank (20000 mAh). I'm very happy with it. I was looking for a reliable power bank for my laptop, and this one fits the bill. It's a great product that provides reliable power to my laptop and can even charge my phone at the same time. I like the built-in USB-C cable that really makes it a very convenient way to reduce the amount of items carried when traveling and working remote.
I would recommend this to a friend!

[This review was collected as part of a promotion.] Received this Powerbank in a timely manner. Chargers my laptop without any issues when I don't have access to an AC outlet. Works well charging my touchpads.
