hello very good review....i have a question.. the amazon link says 9000mah but this projector only brings 3000mah which it says in your video too, do they all come like this?
@@korvaxgekvykeen9026 Thanks for your interesting and question. J4a designed with 3 packs of 3000 mAh batteries ,last more than 2 hours on a single charge
The remote control that comes with J4a is actually an air mouse but you need to do bluetooth pairing with J4a first. You can go to Settings/Bluetooth/Search. Simultaneously press enter and return key on your remote. When LED indicator on remote flahes from fast to slow. J4a Blurtooth search will show BLE Remote on the device list. Selet it and press enter. After Bluetooth being paired, you can use it as a air mouse. You will find it very convenient. By the way, remember to upgrade your software. You can go to Settings/ Upgrade/OTA to do so. Make sure J4a is already connected to internet before upgrading your software
