Refurbished electronics (or refurbished technology) are electrical items (think phones, laptops, PCs) that have been sold to a company that fixes, debugs and resells the item on to new customers. It is a reseller’s duty to describe the condition of the item as accurately as possible.
The reseller will then send you the device with the basic peripherals required for it to function, such as the accompanying charger to a phone or laptop.
In some cases, the customer has simply sent in their electronic devices because they changed their mind but cannot return it to their main seller. This makes it virtually new, meaning you’re receiving a piece of tech that’s fully functional for far less money. What a steal!
