Do These Use A Lot Of Electric To Charge ?

Is it expensive to charge as it can take up to 6 hours ?

No, they don't cost a lot to recharge.....it's not like an immersion heater or a radiant fire running for six hours. It's a very small amount of power being used to recharge a (probably) lithium rechargeable battery....not much at all, even though it's on for six hours.
