Anker PowerCore II Slim 10000 Ultra Slim Power Bank doesn’t charge fast

this charger doesn’t charge fast.

I recently purchased the Anker PowerCore II Slim 10000 Ultra Slim Power Bank, Upgraded PowerIQ 2.0 (up to 18W Output), Fast Charge for iPhone, Samsung Galaxy and More

I had 1 blue charge light on 5 hours ago I have had it plugged in charging since then and it is still on 1 blue light How long should it take to fully charge ? Is this abnormal?

Your usb wall charger. If your using a 5v 1A wall charger it’s gonna take longer. If you use a 5v 2a it should charge more quicker


A 10,000mAh power bank will take about 12-14 hours to charge with a regular USB wall charger (like an iPhone charger). It will take about 6-7 hours with a 2 amp charger like an iPad charger or one of Anker’s wall chargers. So the charging time seems normal so far.

If you have any further issues, feel free to reach out to with your serial number and order number for further assistance. Thanks!
