USB to SATA Interface Adapter – These amazing devices are essential for those times when you have to replace a computer’s hard drive or SSD. They make it easy to transfer the data from the old drive to a new one, and they can even be used to convert a spare internal drive into an external USB drive.
Battery Backup Device – If you have ever been installing an operating system or critical updates when the power went out, you know what a hassle that causes. That’s why you should always have a computer plugged into a battery backup device while you’re working on it and it’s powered up and running.
Anti-Static Mat and Wrist Strap Combo – Static electricity can easily damage an electronic item or even destroy it outright if proper precautions aren’t taken to prevent accidental static discharges when working on tech gear. It’s wise to always use an anti-static mat and wrist strap when working inside a device, even if it’s just something as simple as installing a RAM stick.

Cans of Compressed Air or a Data Vac – Any time you open the case of a computer to work on it, it’s a good idea to blow the dust out of it while you’re in there. A thick layer of dust can restrict the air flow inside a computer, causing it to overheat and act erratically. I don’t recommend using an air compressor to blow the dust out of computers for the reasons stated in the post I linked to above. That post also explains why I recommend using either a can of compressed air or a data vac.
Anti-Static Screen Wipes – Regular over-the-counter glass cleaning solutions such as Windex can damage the screens of TVs, monitors and mobile devices. That’s why I recommend that you only use anti-static wipes that were specifically made for cleaning screens.
Online Technical and User Manuals – It always helps to have a manual on hand for any device that you happen to be working on, but you usually won’t. But you will probably be able to download one for free from either the manufacturer’s website or from Manuals Online.
