Is anyone's PowerCover charged so slowly as mine?
Yesterday, I got my PowerCover for my Kobo Sage. I find that it is very very slow to charge it. Actually, it took me circa 8 hours to fully charge the PowerCover!
I checked the official website of Kobo. They write that
But none of these happened to my PowerCover. I use a wall adapter but my Kobo Sage always tends to be charged first. Not until my Sage's battery was full, my PowerCover began to be charged. It was too slow. It took 4 fours for the PowerCover's battery to turn from 0% to 42% and it took 3 hours to turn from 62% to 94%. More ironically, the percentage dropped quickly. It consumed 20% in 2 hours. I did not use my machine continuously. I just read some passages while waiting for my supper. Let's think: if it needs 8 hours' charging but can only endure for 8 or 10 hours, what is the point for me to have it? Is this normal? What is your experience? Should I ask for a refund? |

Saw this after I web searched, and realized what I was seeing was true. I actually put it on a USB-C powermeter while charging it and lo and behold I got 4.98v @ 0.51amp (2.54 watts).
when I selected a higher power plug (20 watt on the Caldigit TS4), I got 5.25 vaolts and only 2.2 watts (yes the amps were lower). Charge time for a depleted sage? 3.6 hours and if the cover is the same charge time ... well 8 hours is in the ballpark. |

My Sage, with no cover, charges at about 1.5A, on a compatible charger. A current of 0.5A on a 7.5W or 10W or 20W charger means it's not compatible. Typical full charge is under 50 minutes. Typically gets recharged on PC while connected to Calibre.
Sadly there are many charging standards. |

For what it may be worth, my PowerCover and Sage both draw ~1.5A/5V while charging. It takes about 95 minutes to recharge both from 10%. OTOH, I mostly use the SleepCover since I read mostly at home where I don't need the PowerCover to extend battery life. It's very likely that without having the PowerCover gifted to me, I would not have bothered to own one.
