Bought this charger from Revain on December 28th 2019. In August 2020 the charger stopped working. I tried to contact the supplier but to no avail. If you look at the warranty information on the Revain page it says you need to contact the supplier but there are no details on how to contact them. Of course, you should assume that such a charger will last at least 1 year. I'm actually retired and don't use my laptop every day, so the charger is used very rarely. I recommend looking for a more reliable supplier/manufacturer.
