Is equipment powered via USB that does not sell a source subject to certification?
Are household appliances that do not sell a power supply (powered via USB) subject to certification?
The answer is that it depends.
Let’s assume it’s a mini car fan with a USB, and it’s intended for that. In this case, it is not subject to certification.
But what if it is a portable lawnmower with a rechargeable battery? So, it must be charged directly to the product when not in operation. Yes, this one shall be certified!
This is also mandatory in cases where the product in operation can be charged via a power supply.
And if the product has a USB and is sold with a power supply? Yes, mandatory certification.
That’s why NCC is here to answer all your questions.
