I bought this accessory for my daughter and I must say it's pretty well designed simply "drop" the DS XL on this basis that this one is put in charge. No need to connect the charger to the rear load occurs through contact, everything goes smoothly. Additionally, if you wish to do without the base, nothing more simple, this one is connected to a DS XL charger, so you just have to connect the charger directly on the DS XL ..... Useful traveling by example.
