I am looking for a Interchangeable plug type adapter with BIS (Indian) approval .
Hi Vinutha,
You are right Raspberry Pi 4 charger is not BIS certified. But you can use any BIS certified USB adapter with 3Amps output.
I just saw this in amazon. https://www.amazon.in/Powerup-Charged-Certified-Adapter-Smartphones/dp/B07D9NKQCQ
The other option is getting Raspberry pi charger BIS certified. I am not sure how much will that cost. Since it has FCC Part 15 SDOC ICES-003 CB Test Certificate GS Certificate LVD 2014/35/EU certificate UL Energy Efficiency Certificate NOA UL Leaf Mark SAA RCM . Getting BIS won't be a deal. But again it may cost you a bit. If your application has that budget bandwidth go for it.
Regards,
Aswin
