ZMI PowerPack 20K Backup Battery & Hub Bundled with ZMI Turbo 45W USB-C Power Adapter for MacBook 2015/MacBook Pro 2016 or later, Pixelbook, Pixel, Surface Go, Nintendo Switch, etc. USB-C Battery Pack

I did a lot of research to find a USB-C PD battery pack that could charge the few USB-C devices I have (work Macbook Pro, personal Dell XPS 13 9370, Switch, iPhone via USB-C to Lightning cable), especially the Switch in both handheld and docked modes (I bought a small USB-C to HDMI hub so I could use it in docked mode without bringing the official dock around). This battery, while a bit bulkier than my previous Anker 20000 USB (not USB-C) battery pack, performs amazingly and charges quickly via the included 45W charger (folding prongs, non-permanent USB-C cable, $5 cheaper than buying separately).All of the other 20K+ batteries that provided at least 40W via USB-C PD were at least $20 pricier and appeared much bulkier. The other option I was considering was the Jackery Supercharge 26800 PD which I also liked but unfortunately appears to not support charging on a docked Switch.The only two small annoyances were:- hitting the side button to check capacity first lights up all 4 of the lights, before showing the correct number of lights (e.g. 3 out of 4) to indicate the remaining capacity.- the carrying pouch is so tight that it's hard to pull the battery out of the bag, and it can't even carry the included cables in the pouch due to the tight fit all around the battery.I haven't had a use for the USB hub functionality but it's good to know it's there, especially when I always carry this battery in my backpack but don't always carry a USB-C to USB 2.0/3.0 hub.

I'm able to charge my Pixel XL a few times with it and, unlike my previous battery, I don't have to turn it on first or risk having it drain my phone to charge the battery. It just starts charging when I plug it in. I also used it to charge my PS4 controller the other day without issue. The battery shuts itself off when the device is fully charged.It just *barely* fits in the little drawstring bag it comes with, with absolutely no room for even a small cable, which is a little disappointing. One of the cables it comes with is USB-A to USB-C, but the C end is actually a little adapter on top of a micro-B connector, which is handy as I still have a lot of devices that use a micro-B connector.The charger it comes with charges my phone pretty damned fast (I take the phone out of its case because it gets hot). The phone doesn't seem to charge quite that fast off the battery, but I haven't done any real comparisons.

Charges pretty fast, provides a ton of power for a USB-C laptop, Nintendo Switch and Phones, and the built in USB hub is genius and is a great port expander for small form factor devices with only one USB-C port. The only complaint I have is that the plush bag it comes with for storage could be a little big bigger. The battery is hard to get into it, and it would be nice to be able to store the cables with it in the bag.

It fast charges my Galaxy Note 10+ and my Note A 10.1" tablet very fast.I wish the USB hub is USB 3.0 or 3.1, but, it's still pretty awesome to connect USB peripherals to my Android devices while charging them. I can literally use my Android phone and tablet like my PC. Wired network connection, Serial console port connection, Bluetooth or USB keyboard and mouse.

This is the largest capability battery allowed on airplanes (apparently) and it comes with USB-C output. What more do you need when you and a companion are traveling and have access to plug points only at night in hotels?

A great battery until it stopped charging and pack started to heat and EXPAND. I dispossed of it for fear of explotion, but while it worked it did at its best.Great battery, sure hope it would have lasted longer. Solid 3 years out of it.

The media could not be loaded.  Bought two ZMI PowerPack 20K just over a month ago, and one of the USB A ports on each stopped working. On one battery, it was the one close to the button, and on the other battery it was the one away from the button. Was good while it worked, but can't use now.

Works great for phones and nintendo switch. Also works to power the switch in docked mode with the standard dock and bionk lynx cables
