- jeffbee 3y agoUSB-PD goes to 48V https://www.usb.org/usb-charger-pd https://www.usb.org/usb-charger-pd
- jjeaff 3y agoInteresting. Unfortunately, that is not quite enough to charge a 48v li-on battery. You need something like 52v.
- lxgr 3y agoIt goes up to 48 V these days! That's still "only" 240W, i.e. not nearly enough to charge electric bicycles. The other direction would still be nice, i.e. for faster charging of phones mounted on the handle bar.
- jeffbee 3y agoThe whole line of Specialized e-bikes charge at 42V, 2 to 4A. USB-PD 3.1 would be more than enough for an e-bike.
- lxgr 3y agoOh, I wasn't aware that the charging power was so low!
- Cthulhu_ 3y agoCaveat, bikes are outdoor devices, it's probably better to have wireless charging on an e-bike.
- lxgr 3y agoMany phones have been waterproof for a while now, and I've used at least one that's told me that I had moisture in the charging port, with charging being paused while that was the case. I'd rather take my chances during the few times I need to really charge my phone in the rain over the inevitably slower charging speeds and inefficiencies that go with wireless charging, especially when the power source is also a battery.
