answer:I haven’t seen any blood pressure monitors that are rechargeable… But they don’t use much juice. I change the batteries (2xAAA) in a lumiscope 1143 about once a year with less than daily use. I also haven’t seen any blood pressure monitors that would give you a continuous reading either, not sure that’s possible or healthy… in order to get the systolic reading as-far-as-I-know the device will note the pressure at which the beat is no longer audible, i.e. cut off. (I do Not have medical training of any sort besides CPR so I’m not positive about that). There are lots of sports watches that will give you continuous heart rate measurement, that’s your “pulse rate”.
