This is a great little scale. It does not say anywhere that it is rechargeable. It does have a micro usb power port. Upon teardown, this scale does NOT have a backup rechargeable battery. It is powered by two AAA batteries that are secured with four size 0 philips screws (driver included) or powered by the micro usb power port. To save you on frustration when you buy this, there is no recharge feature, just battery or usb power supply. This scale is Oh So very sesitive. How sensetive you say, well it changes as you breath and when the kunty wind blows or gusts. It is sensitive enough to change the weight of an object on the scale, if the operator is having heavy thoughts. Overall pretty sturdy accurate portable pocketable lil scale. The included calibration weight is great, all scales should come with a weight for calibration. Let's not get stupid though, 👆👆👆and ass ume every usb power port magically provides a rechargeable battery or rechargeability.
That's all the time I have for you, circus animals,
