ChargeTech Portable Laptop Battery Pack (36,000mAh) - Portable Charger Powerbank is Compatible w/All Laptops and MacBooks (TSA Approved for Airline Travel) [Black]

This is the second time I bought. The first purchase price was $20 or $30- higher and I ended up giving that one to my brother as a birthday present. I use this product for all my portables. It came with a carrying case and magsafe 1 and 2 connections and a usb-c connector. Works great with my older macbook air right out of the box. I usb-c charge my Microsoft Surface Go with the help of a CONMDEX magsafe 2 to usb-c convertor. Using this set up, the Microsoft Surface Go charges from 10% to 80% in 30 min, 15 more minutes to 100% That is way fast. Looking at the fine print on the side of the CONMDEX convertor, the CONMDEX unit's usb-c should be putting out 15v/3amp. I use the battery for work and travel and as backup to power numerous mobile devices for my kids when we go out. I have used it for stable uninterrupted power for a midi controller/PC setup for a soft synth station. It is portable, but it is a brick and in the hand feels about as heavy as a 11-13 inch ultralite laptop. I ordered it in silver, but it came in black. I don't mind. It works. I gave it a solid 4 stars. I would have given it 5 stars if charging the unit was faster. It takes something like 4-6 hours to charge it from empty with the included AC adapter. I ordered a car/cigarette lighter adapter from Chargetech for $10 but it doesn't fit this unit's charging input. Must be for one of their other batteries. Bummer.

Charges my Surface Pro 4 twice. You do need to buy a cable, but the unit comes with a nice carrying case which has room to store the cable.Recharge was fast with the AC adapter. Props to them on using an AC adapter and not USB charging.

Amazing power bank.Good for travellers especially for camping etc.Charges my macbook air 13 inch 1.5 times in 1 charge.Charging is fast and hassle free.Love the bag and 3 cords that come with it1) L type connector cord magsafe 12) T type connector magsafe 2and3) usb type c cordEnsures coverage accross all macbooks.Havent faced any issues whatsoever . Been using for more than a year now.Many a times while binge watching at home you dont feel like getting up atall from bed. Those moments are when this is your best companion. Yeah am damn lazy. Lol

This is of great use to me. I can leave my iPhone in the car to charge, so to not rely upon the car running to charge my phone and iPad. Solid product...Except...* One of the USB charging ports is very fragile and the separator in the port broke loose after very little use. I will exchange the item for a new one soon. I can also use the battery pack to run my MacBook Pro. This will be of great use when hurricanes hit (2 in the last two years). I bought two for emergencies. I have not been able to drain the battery even after charging my iPhone and iPad simultaneously.

Great battery pack with lots of juice to power up many different devices.I plug in my laptop, ipad, iphone, ipod nano etc...I Will be taking it with me on the plane to power up my phone and tablet for those longer flights to keep me and the kids entertained.
