About the AC Adapter Many newer Freeplay products use the mini-USB charging standard, allowing you to buy just one AC adapter to charge many devices. By avoiding including an AC adapter (wall charger) with every product, we keep prices down, and we lessen our impact on the environment. There are already 1.5 billion AC adapters in use in the USA – that’s 5 per person – and that’s just in the USA. This standardized approach will greatly reduce the problem. Products that use this charging standard also have the advantage that they can be charged from a computer's USB port, using an inexpensive cable (USB-A to mini-B, 5-pin not 4-pin). You may already have a mini-USB AC adapter. If you don’t, this one will power not only Freeplay products but other devices as well, such as many mobile phones and digital cameras. Benefits Charge from the wall for extended shine times and play times of your Freeplay products. One charger for many products, not just those from Freeplay – less clutter, less confusion. Universal power supply with USA, UK and European pins supplied lets you carry one charger and use it anywhere. You may already own an appropriate charger, and only buying the charger if you need it means less waste and less cost – both financially and to the environment.
