I'm after a specific thing, can anyone help

[H0TBUZZIN]

My DM needs a clock, digital.
It can't have batteries and it can't have a wire. But it can be rechargeable, like with a usb.
I can't find any.
She can't have wires or batteries but can give it to someone to recharge and give back to her if that makes sense.

I've been looking for twenty minutes, does this thing exist?

Sounds good, please can you send the link

Can't have a watch unfortunately

If it wouldn't be taken as insulting, I think some of the ones intended for sleep training are USB rechargeable, aren't they?

I just found this one randomly, no idea if if it's any good:

Or it could be better to go for a known big UK brand, for safety?

On reflection, maybe not the one I linked as the reviews say the blue light cannot be dimmed overnight, but you get the idea.

The link is showing for me. Here it is again:

I think this one might work?

@H0TBUZZIN if you search Amazon for "rechargeable usb alarm clock" you'll find several options - but read the descriptions carefully, some have just a backup battery for power-save mode in the event of a power cut.

Some of the genuinely rechargeable ones will use removable AA or AAA NiMH batteries, but with most of these you should be able to glue the battery compartment shut without affecting how it works. It depends how secure the unit needs to be to prevent the user accessing the batteries - any wireless digital clock will have batteries that can be accessed by bouncing the unit off the floor/wall hard enough.

@H0TBUZZIN The link I posted earlier does work for me but I’ll try again Digital clock

We’ve got this one. Only needs charging occasionally. The display goes dark unless you tap it or make a noise though (probably battery saving). It comes on v easily.
