Shipping was extremely quick. The device seems to be of very good quality. And the seller reacted immediately to questions and solved issues. Fully recommend seller and product.

I'm VERRY happy with the device and its capabilities. It supports all requirement that I have been looking for (charging and discharging at the same time, USB-C PD output) and even more- it can be used as UPS in the event of electricity distractions- connected equipment does not feel when electricity is gone in network. This battery does supply power without any delay! Communicated with seller a lot, and he is TOP in responding to questions. Highly recommend this product and this seller.
