Keep power Type-c 21700 rechargeable button top battery why were they ever made? If they are too long for almost every device. What devices - torch - lamp - will they actually fit in? I cannot find one right now

[Jesusandbible]

Can you help with this issue? There are 21700 button type batteries, that are a bit longer, which have a USB-C for self charging with no separate charger. But as they are a bit longer, none of my torches or radios can use it. What lamps radios or torches will take 21700 button top usb-c batteries in them? Thanks! Anyone know??
