Mobile charger instead of Three AAA batteries

[Mubashar1122]

I have a messager using Three AAA batteries (4.5 volts total) but the batteries drained too quickly so i have to buy new ones almost daily. Can i use a mobile charger i.e 5.0V≈2.0A instead of Three AAA batteries.
Just cutting the data Mobile charger instead of Three AAA batteries and plug it to messager???

Welcome to EP!
I don't know what a 'messager' is, but if you mean 'massager' (i.e. a motor-driven device) then I'd say the answer is yes. My house doorbell was designed to be run from 3 AA cells, but it's been running happily from a USB charger for the last year or so.

Yes but you could instead just get NiMH rechargeable batteries to retain its portability. Why you would not have done this already instead of buying batteries "almost daily" is beyond explanation.
