I have yet to run a controlled experiment to prove it, but I think I’m seeing extreme self discharge on a pair of Powercore 10000PDs, in the order of 25% of capacity in a day or two.
Would leaving a USB-C to Lightning cable plugged into it drain the battery? I believe there are chips in the cable, right?
How are you conducting this test? While the cable does have a chip, it shouldn’t be drawing any power unless the phone or tablet requested it.
The way I will do the test is to fully charge the two units I have, plug a lightning cable into one, and then not touch them for two days.
I was just wondering if it was a known issue.
Only if there is a device on the other side of the charger
There maybe a small small draw, but so negligible. It certainly wouldn’t drain that much in such a short time.
Anker suggests using within 4 months if charging, so they shouldn’t self discharge like that.
I guess you’ll just have to believe me about my method, but I did the experiment and this is the result—after two days left sitting in a dark wardrobe, from a full charge, the one with the cable plugged in has discharged by a quarter and the one without the cable hasn’t.
How do I summon an Anker engineer on the forums?
From support:
May I know the USB C cable you mentioned is a USB C to lightning cable? If so, it will consume power when you leave a USB-C to lightning cable plugged into the portable battery as the chip in the USB C to lightning cable can be detected by this PowerCore 10000 PD. Please do not leave cables in the portable battery if you do not use the portable battery.
Ahh that makes sense with the iphone cable, I completely forgot about the authentication chip that allows it to charge properly
