Wheel Analytics includes a USB power supply with three ports when only one is needed. Wall sockets can be a precious commodity so this supply is ready for triple duty. True wheels without losing your phone charging port. Or power a tablet, which might be used with Wheel Analytics at the same time. The WA-1 is a low-power instrument and will work happily with any of the ports. Save the higher current port for heavy-draw rechargeable devices. Select US-style, EU-style or UK-style plug at checkout.
Update: AU-style power adapters of a different style now available.
