Omni 40C+ 38400mah/142wh Professional Premium Portable Power Bank with 100W USB-C Port – Laptop Power Bank, Universal Charger for All Devices, Fast Charging USB-C & QC 3.0 Ports, HDMI & SD Card Reader

I was skeptical of purchasing this for my college age son because of the expense. It's been about a year, and this power bank still fills his expanding needs.

Great power bank, works better than its more square brother that also does A/C because it has more controls, more flexibility, and just outputs usb power and dc power when connected to devices I want to have externally powered. Many power stations simply negotiate with the devices plugged into them, and I want to override that action, and this device seems to be able to do that. Liked it so much I purchased 2 more, and now my 4 more square Omni Charge cousins are relegated to back room duty.

Super expensive but one of the best things I've ever used for any charging station. Love it.

Durable good charging speed good value great battery life would recommend.

This portable charger is huge but offers all the power charging options anyone could ask for.

I charged my laptop and was amazed! Ability to charge is very good! Lightweight, portable, functions great, & build quality is well maade!!!!!

Update 09/8/25: After less than a year, the unit is now dead/unusable. I noticed after a couple months, the unit would discharge when not in use. If allowed to discharge enough, it would refuse to charge from a PD charger and I would have to use an older non-PD charger to bring it back. Perhaps it discharged too much because now it won't charge or come on. Hopefully an isolated problem and not an inherent design issue. Could be dangerous considering the battery capacity... Original review: This thing is a little different than the usual portable power bank... It is very-well built and has a nice hefty feel. I didn't 'objectively' test the capacity, but it certainly packs a punch. It arrived at less than 20% capacity. Per the instructions, I fully discharged the battery to 'calibrate' the metering. I had to charge almost everything around to accomplish this: topped of 3 phones, a couple headphones and played with a laptop for a while... The device supports 'super-fast charging' for phones, PD for laptops, etc. The included power supply charges the device as advertised. It doesn't fit the usual portable power bank mold. It's large and better suited for laptop UPS use or for use in a conference room to distribute power to a few laptops... With a few more features, it would be an excellent UPS and docking hub for home or work office.
