5. Can charge laptops Max.90W-100W.

6. Double click the power button to set the voltage before charging from the DC-OUT port.

7. It will turn off automatically after 1 minute to save power if no device is connecting to it.

Tips:

Low shutdown current for USB & TYPE-C ports: 50mA

High shutdown current for DC-OUT port: 5V / 8.4V / 9V / 12V >3A; 16V / 20V >4.7A

If the power bank shuts off after 1 minutes, it's due to the current of your laptop being too high. Please don't use your laptop or close the screen of your laptop, then charging it with the power bank.

How to Check Whether My Laptop Will Cause Power Bank Overcurrent or not?

Please Check the label pasted on the adapter. If the output is more than 4.7A, it may cause overcurrent. So we don't suggest to use this power bank to charge your laptop.

31 customers mention23 positive8 negative

Customers like the capacity of the power bank. They mention it has a super large capacity, it can charge their iPhone or tablet, and it's compact despite the large battery capacity. The 50,000mAh is huge and is enough to charge smaller things like phones. It's a little heavy, but since it packs so much juice it'd be pretty reasonable. The lesser unit also carries twice the charging capacity. Overall, customers are satisfied with the capacity and recommend it to others.

"...Overall, highly recommended. Fast-charging, long-lasting, so far it’s been very dependable for a number of uses...." Read more

2 Years In and Doesn't Measure Up

2 Years In and Doesn't Measure Up
I've had this power bank for approximately 2 years now, using it to keep my 8" Galaxy Tab A - which I use for reading - charged, I recently noticed that it was running out of power faster than I'd expect for a 5,000 mAh device.So I hooked it up to an ZKE Tech battery tester I use to take a look at my rechargeable batteries. This tester connects to a PC using a USB cable, and has software that allows you to set the discharge rate and cutoff voltage connected to the tester itself. What I found was that the Power Bank isn't performing anywhere near what the specifications say. The tester rates it at 2,000 mAh hours, not 5,000 mAh. As for it's cutoff current, at 5 VDC it cuts off in under a minute at 3.0 A, rather than the 4.7 A advertised by the manufacturer.The good news is that 2,000 mAh and a max current of 2.75 A gives you a nice long time to keep your Galaxy Tab A working. It's just that it's nowhere near what the manufacturer claims.
