50,000 mAh (milli-amp-hours, or 50 amp-hours or 185 watt-hours) of power make this battery pack an excellent traveling companion if you expect to be away from AC outlets for a period of time. As a storage battery this unit is excellent! I, however, bought it for a different purpose and it is just as excellent for that purpose, too! I bought a mini-PC (beelink) and a drawing tablet which includes a video screen (XP-Pen Artist Pro 13.3) which draws its power from the mini-PC's USB port if desired (the drawing screen can also run off an AC plug-in power supply). I want to be able to take this mini-PC and drawing screen out in the back yard or traveling, and need a portable power supply. This MaxOAK battery pack powers the combination perfectly and provides many hours of use before needing to be recharged. I have not yet done a total run-down of the MaxOAK with the mini-PC and drawing tablet plugged in to see how many total hours I'll be able to get out of it, but I have used the combination for over 3 hourse and LED "power-remaining" indicators only went down from 4 to 3 over those 3 hours, so I'm expecting to get a lot of usage out of it. Far more time than I get from my laptop's battery and part of why I decided to go the mini-PC route instead of using my laptop.
One factor I love about this battery is that it will turn off if there is no power draw for more than 30-seconds. That means I can leave the mini-PC and drawing screen plugged in and as long as they are turned off, the MaxOAK will stay turned off without me needing to turn it off or unplug it (which was a problem with a different battery pack I had tried). When I'm ready to use it I press the MaxOAK's power switch and then press the mini-PC's power switch and everything starts up and stays on until I shut down the mini-PC, at which point 30 seconds after that the MaxOAK shuts off.
One other excellent feature for my purposes that makes this superior to my other Krisdonia battery pack is that the MaxOAK has a dedicated 20V output jack as well as a dedicated 12V output jack in addition to USB ports. The Krisdonia required me to turn it on and readjust the output voltage every time I wanted to use it with my mini-PC, which was a bother. With the MaxOAK I can leave everything plugged in and simply turn on the MaxOAK and the mini-PC and things work just fine.
The MaxOAK does NOT get hot either while using it to power other things or while it is plugged in and recharging.
Like all these sorts of battery packs with huge capacities, it does take a long time to fully recharge the MaxOAK but that's a small enough price to pay for the ability to recharge other devices or to power my mini-PC and drawing tablet when not close to AC power outlets.
