A:AnswerYou'll get input and range issues with lower-power rechargeables, even with lower-draw BLE devices such as this. Make sure the batteries that you have are capable of providing an actual 1.5 vDC each. Some produce much less.
A:AnswerIt has a dongle, no blue tooth. If it had blue tooth, then it would state it and it would be 3 times the price. Just don;t be like the idiot that threw out the dongle and blamed it on the secure packaging,
A:AnswerDoubtful... at the price point it would not be too onerous the buy a new set or a cheap wireless mouse - yes you'd be taking up another USB port but a cheap USB hub would get you out of jail if required... and again... they are cheap enough these days.
A:AnswerI would take the tablet along to the store... if it has anything other than a female USB Type A connector you'd also need some kind of an adapter... And then maybe it will work...
A:AnswerNot sure I understand the question... I have Specrtum 5G internet and I use this keyboard and mouse with my laptop and using the internet, email etc. Works great.
