How long does it take to charge and how long does a charge last? Thank you

Received mine on Sat/4/9/22 and plugged it in to charge it up. When battery level showed solid black o Sun 4/10, I used it to follow instructions and try it out -- probably had it on for less than one hour. My PT asked me to bring it in the next day (today 4/11) for my session, but when I got up the this morning, the battery was dead. I plugged it in before leaving for PT session at 9:30 AM. It's now 12:40 PM, and the battery icon shows a black space, then a white space, then more black, but the icon is not blinking. I think the battery/unit is defective, so am returning it. I really wanted this unit because of the USB port/easy to keep charged. I'm hoping they aren't all like this!

Does this help relieve menstrual pain?

It helps mine, for sure! You can also visit the iReliev website if you want to ask specific questions- they respond quickly to emails, and have live chat during business hours.

What kind of batteries does it use. A C D???

No batteries!! It charges via USB which should be included! I have had my unit for 2 years and still going strong!

How many channels or inputs does this device have? I'm wondering how many muscle groups I can work on at the same time.

Hello, Thank you for reaching out to us with your interest in our products. This device is Dual Channel. You can use 2 large pads or 4 small pads with this device. Please let us know if you have any other questions. Thanks, iReliev
