I found out why the Powerbank only charged at 9V using the Apple wall charger. The wall charger doesn't offer PD@12V. It offers USB-C PD at 20.5/5A, 15V/5A, 9V/3A, and 5V/3A. It skips over 12V. The full 140W is only available (at 28V) using the USB-C to MagSafe3 cable.
Hey thanks. Here's a link. I use the AVHzY CT3+SM-LD-00 with the electronic load module attached, but the CT3 is the same thing without the load module. www.amazon.com/AVHzY-Digital-Multimeter-Detector-26-0000V/dp/B08J3MPBCZ
@@colindgrant Hmmmmm, Chinese 18650 battery packs are dirt-cheap. As long as you keep the current within spec thru the battery packs, placing N battery packs in series gives you Nxtimes the voltage. In a nutshell seried battery packs can run a lot more electric devices.
@@tombouie These battery packs output power through a QC or PD fast charge controller. There is no bare cell connection from which to connect them in series. The USB outputs default to 5 volts when QC resistances or PD negotiation doesn't come back from the other end. With PD, you can trigger higher voltages, as shown in the video. These battery packs are specifically made for powering USB devices, and their design is 1s16p, all cells are in parallel. So there's really no sensible way to put N battery packs in series. If you're looking to make a high voltage pack from 18650s in series, then this enclosure is not the one for you.
The links are always changing but here is one: www.ebay.com/itm/325068541907 Look for "16x18650 Wireless Charge Power Bank" and make sure to get the 22 or 22.5W model with 15W wireless charging. Leave a like if you find it!

Holy shit I thought I had fill the power bank with battery, I didn't know you can use less battery. Thank you
Great video, please where can I get the charging case. I'm from Nigeria
Hello! I bought mine on eBay. Just search for "18650 DIY Power Bank"
Thank You! Another great video.
Please, how long does it take to recharge the power bank? TY!
It depends on what cells are inside, and their state of charge. But for me it usually takes about an hour.
Good video
Great job, can you link the meter used as well, thank you, gained a subscriber!

@@colindgrant awesome thank you!
Thks & question;
I have multiple USB battery packs.
??How would I combine them serially??
??Is there a hub I can get to combine them??
What would that achieve?
