My car's lighter went out and the USB doesn't hold a charge. Needed something next day before a 7 hour road trip. Based on reviews and price, bought. Luckily, it had some charge so it was fully charged by time the road trip kicked off. I say this because it does take awhile for it to be fully charged.
Fast charging for most of our devices and love both the ports as we can charge headphones and tablets at the same time. At first I had to get used to the weight but once tossed in a backpack for all day tourist-ing, you can barely feel it. I've had it for over a month now and we use it almost daily now. With hurricane season approaching, this makes a great travel companion and emergency charger when power goes out. Definitely recommend!

Seems to Struggle with Higher-Speed USB-C Devices
This battery bank is advertised as having a capacity of 37 Wh (Watt-hours) of energy storage. NOTE: NO electronics are 100% efficient. I found that 5 Volt output was efficient for this price class at medium loads [85%] but I found the USB-C efficiency when fast charging a demanding device was only 43%, which is not what I'd expect from the Anker brand name.What does this mean for you? If you're hoping to charge a tablet with this, you may be disappointed by its performance if you use a USB-C to USB-C cable, as the table will be more likely to negotiate higher energy draw from the bank than it would if you carry around a USB-A to USB-C cable.I'm hoping thank Anker can chime in here to see if these results are expected.---------USB-A TESTING - 10W - 85% efficient---------TEST SETUP:Anker USB-A Out --> USB multimeter --> USB load tester @ 10-Watt load (about 5 Volts at 2 Amps [2,000 mA]).METER READINGS:Disconnected after 3h, recorded energy output of a bit more than 31 Wh.TEST RESULTS:85% end-to-end efficiency at 10W (5V/2A) - A very impressive result and a win for Anker!---------USB-A TESTING - 10W - 85% efficient------------------USB-C TESTING - 18W - 43% efficient---------**I don't have a proper USB-C load tester, so I had to use a real device which had its own challenges. Towards the end of the test, the laptop I used kept trying to charge the bank...I ran this test twice and got comparable results**TEST SETUP:Anker USB-C Out --> USB multimeter --> Surface Laptop 4 @ 18-Watt load (about 9 Volts at 2 Amps [2,000 mA]).METER READINGS:Disconnected after 50m, recorded energy output of a bit more than 16 Wh.TEST RESULTS:This would imply efficiency closer to 43%. While I expected efficiency to decrease, this was a shock.---------USB-C TESTING - 18W - 43% efficient---------
