I’ve just seen an announcement of a 240W USB-C standard that goes up to 50V so Voltage shouldn’t be an issue charging a bike battery from that.

No I'm proposing that manufacturers make batteries that are capable of being charged by USB-C. All I'm hearing from you is it's not possible without actually thinking how it could be possible. In RC, it's frequent to use multiple batteries to push up the voltage, there are also electric...

Take the Brompton Electric. It has a 300Wh battery. I think the rule of thumb is that it takes 1.5x the capacity to charge a battery to full, not sure if that rule is appropriate for lithium chemistry but let's go with it. So call the 300Wh 450Wh and let's say we have a 100W charger. That would...

The wattage on USB-C chargers is there (at least 96W) but they typically have a maximum of around 20V. An electric bike could use a 20V battery or better it could use a pair of 20V batteries or a single battery that is internally two 20V batteries that get connected in series when in use, either...

I’m waiting for the day that everything goes USB-C. Solar panels with USB-C direct into a power bank. Then out into a USB-C port on the battery. Have you cycled to work and your battery is low? Plug it into your laptop’s USB-C power supply. And vice versa. I’m surprised no manufacturers have...
