Need a charger 2015 prius plug in

Just search 'prius' under the question box in the chargers u see in Amazon. You should see reviews from other Prius owners and they usually say their year/generation and how they like the charger.

 

Pretty much any J1772 EVSE (What you'd call a charger cable) should be fine.
Basically the PIP(Plug In prius) is at the bottom end of charging requirements.
The only thing you'd possibly consider is buying something higher power for a future car. (which would be fairly likely to require upgrades to your house to supply more power)

The EVSE is basically a smart extension cord, so you don't have to worry about too big or small as far as your car. If it has a higher capacity than your car then you just won't be using the full capacity of the EVSE. If the EVSE has a lower capacity than your car, then your car would just charge slower.


That said, as far as burning down your house goes, that's more to do with the outlets where you'll be charging. I'm guessing we're talking about a 120V EVSE. The car will more or less be like leaving a hair dryer or heater at full power for 2-3 hours. So, you'll want to make sure your outlet can support a good 15amps continuously and has a good connection, etc. If you've got other items on the same circuit that draw much power, you'd be likely to trip a breaker. It's not a bad idea to keep an eye on/check periodically when you start charging just to make sure that plug/outlet, etc aren't getting excessively hot, etc. from some weak point you weren't aware of.
