My dad has Parkinson's Disease, so he has poor coordination in his hands and can't plug in small cords like a charging cable.

My sister bought him magnetic USB connectors and it's changed his life! There's a small USB end that plugs into his smartphone port, and the cable connects to it via magnets. Takes my dad almost no effort; he just needs to get his phone near the end of the cable and it latches on.

There are regular charging cables and fast-charging cables. Depending on your device, make sure you know which one you're buying. The regular cables take half a day to charge my phone.
