EWEMOSI Portable Laptop Power Bank, 98Wh/27000mAh Portable Charger with 100W AC Outlet, 65W PD USB C QC 3.0 Fasting Charging for MacBook Pro/Air, iPad, iPhone, Samsung, HP, Nintendo Switch and More

May 3rd, 2025 *Initial review - after light usage only* These do what they say, no joke! They arrived fully discharged, which isn't surprising as I was 'watching' these for a couple of years before buying them. When added to my list, they were $90/ea, currently at $60/ea. I have been able to plug in a 4-port USB charger to the A/C port and charge 2 devices (cell phone and another battery pack) then charge a samsung tablet from the USB-C output port, having all items plugged in and charging from this device for about 2-hours. The charger does get warm when you put in under load, but that's what the built-in cooling fan is for. for all that work it dropped 2 out of 5 charge lights after 2-hours, so really not bad (considering the load). I find these very convenient providing a wall-socket where there otherwise would NOT be one. I have not done any overload testing or torture testing yet. the images and video from from today, as I'm writing this review. I connected my phone (Moto G Stylus 2023 w/5000mAh battery) to the USB-C PD port of the battery bank and the footage shows what the ammeter was reading. Charging does vary dipping down to about 14W up to about 25W over sustained times, but its putting out 9V sustained.

Powers my laptop for about 1/2hr - 3/4hr 👍

Only worked twice And now will not charge my computer anymore at all and charges my cell phone super slow if at all

I purchased this battery bank for a workshop I was attending. If you've ever attended a workshop or conference, there's not any available outlets near your sitting area. Purchasing your own personal battery bank is a great idea. This battery saver is perfect. It has several different size USB with one DC outlet for those laptops with a DC power plug. Before using the battery you ahould make sure it is at 100 percent compacity for use. The blue lights will show you how much available usage (charging) left. Perfect for those who travel a lot. Although the battery bank is a bit on the heavy side, I love it for the many available USB sizes. Great for charging your cell phone, laptop, etc.

I use this power bank to power my pc terminal. Well worth it. It can be charged via usb-c with solar power. (Remember to be outside and not try through the window). The flashlight can be accessed by double clicking the power button. A must have for mobile employees.

Takes forever to charge and is quick to drain. I have had smaller units with more juice.

Great car accessory for long trips

This works really well for charging my cell phone on the go. I also use this as a batter/power for a set of Christmas lights (120v) that I keep in my classroom in case the power goes out. The only draw back to this battery is that it discharges rather quickly (when I use if for cellular devices like my cell phone, rechargeable flashlights, and iPad) it drains after about three to five charges, even in cool to warm weather. Overall, i'm happy with my purchase.
