I could not find the charging instructions either on the box or on the small section of English on a huge Warning Sheet from within the box. I did find the charging instructions on this site, which state,” A completely full charge takes 12 hours - the red light indicates that the clipper is charging successfully and does not change colour or go out to alert that the charge is complete”. So by rights you have to make note of how long you use it and charge by that amount times twelve so as not to overcharge, what a faff! Even the cheapest chargers available have colour changing LEDs? The miniature oil bottles that are supplied with clippers are also frustrating; in the box you will find them supplied in a zip-bag. Once the bottle is opened you will find the zip-bag has better sealing qualities!
Good piece of kit this,gives a smooth level all over cut on grades 1,2 and 3.
I purchased the clippers during lockdown for my grandsons very pleased with the results. Brilliant colour coding as I am a novice at cutting hair.thank you.
