Finally! Cig Lighter USB Charger With A Pair of

My S4 mini can only pull One amp.

But still on the cheaper USB supplies I have, they cannot maintain 5+ volts when providing 1 amp.

The BlueSeas product does maintain 5.09v.

This source, with a 1' long Anker microUSB cable charges my phone significantly faster than any other USB supply I have, and faster than the source and cable provided with the phone.

This is the product which lets me see USB voltage and amperage.
