User Reviews about Dsi AC Adapter - Black

Works fine! you can charge on 110/220 voltage or you can charge from any other USB slot, like a computer, or a Wii, or a TV that has USB. -- cool ac adapter

This is a dual dock charger for Ipods. We have a nano and a touch and they both charge simulaneously! It is awesome! -- Dual Dock Ipod charger

There are not many AC adapters for the DSi which support a 240V power supply. Even this one I had to wait for a while to get. This adapter can be used to charge the Nintendo DSi by connecting to the USB port of any computer which makes it a very useful feature.
Another nice feature I found about this adapter is that when connected to the power socket and either the DSi is not plugged in or the DSi has been fully recharged, the adapter makes a small sound (kind of an alert) which indicated that some attention is required.
It also works finely with a 110V power supply.
On the overall this is a very good replacement power adapter for your Nintendo DSi. -- Good AC adapter for the DSi
