refurbishing

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.
The sale of refurbished electronics is part of the circular economy, and refurbished devices are often promoted as a solution to the problem of electronic waste.
