How long does a single charge last?

High heat is 3 hours and medium heat is 5 hours. There is an on setting and a heat setting; if you only use the on setting, that will deplete the battery at 2% per hour.

Mine lasted about 3 - 4 hours. However, I used them in my ski boots not regular boots, but I would imagine timing similar. However, I kept mine on low setting. These work OK.

It depends on how long you have them on and if you have them on low or high. To extend the battery, you should turn them off with the switch on the back of the insole. Turning them off with the hand device will turn off the heat but not the energy released.

A charge will probably last about four to five days 3 hours a day and it will work while charging.

I usually charge overnight and the charge will last for 3 or 4 hours, although I am guessing - I haven't really timed it.

I've only charged mine once and forgot about it for a couple weeks, I just used it yesterday to type this review and it appeared to be nowhere near empty so I'd say it holds it's charge very well. Back when I used it more frequently I could go two days on a single 4 hour charge.

I've had mine for months and only charged it the initial time. I don't recall how long it took. I only use it a couple of times a week but the charge has held.

I get about 8 to 10 hours on a charge. I also have a Mini usb charger installed on the bike so when ever i have long ride and I stop to take a break I plug it in to charge.

The battery charge lasts about two hours worth of shaves and one shave takes about 5-6 minutes - so one charge lasts for about 20 shaves. Hope this helps

It depends on the brand. I have one that is "Tenergy" that takes about 4 hours to charge, but then I have another one by UltraFire that takes about 3.5 hours to charge. I have also notice there is a significant difference in how long these will last in the same device. The UltraFire lasting about 25% longer. as for whether you are charging one or four at the same time doesn't matter. Each bay charges individually.

I initially charged my battery once, for a full day. After that a normal charge takes 3-4 hours.

I would guess several hours, I didn't keep it in constantly after a charge, but using it 20-50 minutes at a time a few times a week, it lasted over a month for me.

About 6 hours but I bought 8 of them and one stopped accepting a charge after less than five cycles. It was only four months old but the Amazon seller would not replace the faulty one

Up to 4 hrs, but it takes awhile to drain the battery. Everyday use for a week and still running in a single charge.

Well I play usually 6 or 8 hours, then simply redock it in the charger. I've not left it undocked to know how long it lasts. I'm sorry!

well i've only charged once since it arrived. I been using it for 3 days, about 3 hours with no need to recharge it so far.

Yes. You will get one full charge or about an extra 4-5 hours of steady use.

Hi Eric, I keep this charged and stored in my computer case. The longest I've had it charged without using it was three weeks. It seemed to have kept a full charge during that time. I hope this helps.

About an hour or two. Sometimes it seemed longer to make sure you get a full charge.
