Shopee has. The cheap china ones are sufficient.
Get the one with the bigger batt.
Sufficient to do a decent job, only issue is cannot hit the back coil....of coz, that is to be expected.
Just a cheap proof of concept gadget, is ok.
I got this one, primarily to clean my bike chain after degreasing. Just tried it out on the AC for fun and see how it works vs my pressure washer in which i dial it down to approx half the pressure.
The advantage of this is that the setup/tear down time vs the pressure washer is quite a bit faster.
Actually there is next to no setup time. Just fill up water source, dip the hose in and off you go.

Back coil I mean by this.
