A few weeks ago, ZMI released a 65W USB-C charger that is not only half the size of Apple’s 61W USB-C Power Adapter but also sells for less than one-third its price. The manufacturer is back with a new product – the ZMI PowerPack 20K Pro (ZMI 10 Pro in China) Power Bank which not only supports 65W output charging but also has a pretty cool trick.

Before we dive into the specs of the ZMI PowerPack 20K Pro power bank, let’s talk about its design.
Personally, this might as well be the most beautiful power bank I have come across in a while. Unlike most power banks that are available in white or black, ZMI’s latest portable battery pack comes in blue with a touch of gold for the power button, manufacturer’s name, and the technical details on the back.
The ZMI PowerPack 20K Pro is not just a beauty but also a beast. It has a battery capacity of 20,000mAh which means it is on the thick side (21 millimeters) and also heavy (440 grams). But with what it offers, you shouldn’t be bothered about its weight.
The power bank has a maximum power output of 65W (USB-C PD) which means it will charge compatible computers that require up to 65W charging. It will also charge other devices like the Nintendo Switch, the iPad Pro, and the Mi 9. But that is not all it has to offer.
The ZMI PowerPack 20K Pro also doubles as a USB Hub which means you can connect it to your PC and plug in other USB devices such as a USB-keyboard, mouse, a thumb drive or portable hard drive to it.

The power bank will charge in 3 hours if you use a 45W USB PD power adapter, 5.5 hours if you use an 18W adapter and a quality charge cable, and 9.3 hours if you use a 10W adapter and quality charge cable. ZMI has a long list of compatible devices it has tested, so we advise you to check that out here.
The ZMI PowerPack 20K Pro will come with a travel pouch, 1 x 18-inch USB-C to USB-C cable with E-Mark, and 1 x 12-inch USB-C to USB-A cable. It is priced at $79.95 on the official ZMI USA website but listed as coming soon.
