refurbish

In electronics, refurbishment is the practice of restoring and testing a pre-owned electronic device so that it can be re-sold. Refurbished electronics are therefore pre-owned electronic devices (usually smartphones, tablets, or laptops), that have been tested by a reseller to confirm that they are fully working. Other refurbished electronics include smartwatches, games consoles, and cameras.
Usually, a refurbished electronic device is one that has been previously returned or re-sold to a retailer for any reason. They are then tested, and if necessary, repaired by a specialist refurbisher (or sometimes by the original manufacturer). Refurbished electronics may also be referred to as renewed, reconditioned, recycled, recertified, or "like new" electronics.
