once my smart mug turns off near my last sip... is it possible to use it for a second cup of coffee/tea? do I just refill it again?
I have just been washing it after 1 cup and putting it back on the charger. the instructions indicate that the battery may last awhile which made me think it can be used multiple times.
It really does depend on how long you drink your brew. There is roughly an hour of heat in the mug, with the first half hour of heat having more power than the second half hour.
I'd say if you are a quick drinker you can have a second cuppa without wash/ recharge. However I'd always recommend leaving it on the charger between drinks for that top-up of power/ heat.
