AC Outlet Portable Laptop Power Bank (TSA-Approved), Universal 116Wh/31200mAh 100W Travel Laptop Charger & External Battery Pack for MacBook, Acer, HP, Samsung, Dell, ASUS, Lenovo, Notebook, Black

Picked this up as a gift for my daughter to keep her lap top charge when working away from an outlet. I used this for the last couple of days to charge my lap top and phones. Did a great job and did not need to be topped up. I also tried this on a 17" flat screen TV and it worked well and also powered up a radio with lights and did a great job there too. So if you stay within the power range of this device it will work on many items. It comes with two cords for charging and a wall wart plug. Can also be charged while driving your car or truck via the USB port. Best of all is the really nice semi hard shell case that holds everything perfectly and securely. This power bank has a very solid feel and I am sure will hold up to some hard service. Yep, I do like this one.

This thing has a huge capacity at 31,200mah and can recharge my laptop more than once completely. It can charge my phone almost ten times too. I can't believe how portable this thing is for its size and includes a nice carrying case too. It weighs about 3 pounds or so, so it's not light. You can't really expect it to be though for the power it packs! I'd recommend this to anyone looking for a large backup or travel battery. works great.

You don't have to press the bottom for long time until the radiator is on. Only pressing one quickly then use the usb port to charge your phone. That will be quiet. Great power for laptop on account of 116Wh by 31200mAh. I can use it to charge my camera and laptop.

I ordered this for my son, at his request. He just came home to visit from college, and he was using this to power his laptop. He uses it when on the baseball team bus. He said he really likes it.

GIVES ME AC POWER THAT I CAN PLUG INTO MY LAPTTOPINSURING THAT I HAVE THE ABSOLUTE VOLTAGE TO POWER MY LAPTOP FOR A LONG TIME AFTER THE LAPTOP BATTERY IS DEPLETED, AND MAKES ME SECURE I WON'T FRY THE MOTHER BOARD

We could not get it to charge.
