Camera very simple in its design and conception, it keeps the tablet in an upright position while the recharging. The base is heavy enough to maintain good stability, but is less practical with use of a standard case of the same brand. The load cap is not fixed, it may take them several times before you can properly fix the shelf ... But the cable is long enough and allows a fairly remote use of the power source . Works perfectly with my Galaxy Tab 3 but all android smartphone / tablet models are not necessarily compatible. A list of attachable devices is available on the manufacturer's website if you have a doubt ...
