Less than the cost of a frst party lightning cable
4The last major iOS update invalidated unlicensed charging cables. Since my cat slashed through the official one, all I had left was a cheap unlicensed cable. These were untouched by my cat (since I kept them away from her) but were rendered useless because of Apple's update.
I needed a way to charge my phone. The official USB to lightning wire cable costs $20 from a Apple, and I wasn't happy on spending that.
Meh's JBL speakers charge your phone even after the latest update and cost less than the "official" charging cable. They function pretty well as a speaker doc too.
