This is a product so I'm pleased. Lai I installed next to my computer at home and I get home and I connect I only have to ask my phone (Galaxy S II) or tablet (Galaxy Tab 10.1) supported. No more searching my charger everywhere. This product is compatible with: Galaxy Note 2, 8.0, 10.1, Galaxy Tab Pro 12.2, Galaxy Tab 4 7.0, 8.0, 10.1 (2014), Galaxy Tab 3.7.0, 3.8.0, Galaxy S4, Galaxy S III, Galaxy S II, Nokia Lumia 525, 920, 1020 and 1520. It charges my devices without problems. So satisfied
