A basic toolkit for this trade (screwdrivers, soldering iron, multimeter, winding wire for motor repairs, spare switches/cords) is low-cost relative to most repair trades, typically achievable in the low thousands of rupees for starter tools, since the appliances themselves are simpler than mobile phones or ACs. The formal credentialed route - the government's ITI "Mechanic Consumer Electronic Appliances" trade - is a 2-year NSQF Level-4 course under the Craftsmen Training Scheme, though many working repairers learn via shorter hands-on apprenticeship instead.
No independently verified earnings figure for small appliance repair technicians in India was found, so avoid trusting specific income claims online - per-job value is low compared to mobile or AC repair, so income depends heavily on daily repair volume.
