It was $30 when I bought it, and $24 now is a complete steal:
- Two ordinary USB A charging ports
- Very high capacity for the size and weight - it’s super compact compared to other comparable chargers I’ve used
- Both ports charge at a fast rate (3A total)
- Voltage and amperage is strong enough to charge a Switch pretty fast, and maintain a Switch at the same battery life (if not charge slowly) while playing Mario / Zelda at medium/high brightness
All you need is a USB A to USB C cable, which you can get pretty cheap. Here’s the one I bought which works perfectly:
