what is the charging time from empty battery to full?

I would say anywhere from 30 to 45 min!! This is just an estimate and not a fact.

I have never timed from empty to full. This charger is the same as the original the computer came with.

I haven't actually timed it but I guess it takes between 2 to 3 hours. It depends on if you are using it while charging.

I haven't monitored to see exactly how long it takes to charge from dead to full charge, but I think 8-10 hours should be enough.

I am not sure of the full charge time, however I would guess the charge time would be around an hour to 1 1/2 hours. I have had these batteries about a month now and, I have only charged them twice. Keep in mind, I don't use them everyday, maybe two to three times a week. I hope this helps.

It takes 8 hours for both batteries to be fully charged from empty to full. But most of the time you probably find some capacity remains in the battery, so it will take mostly less than 8 hours. Charge it every night before you sleep, and it should be fully charged when you get up. With full charge, it can run about 20KM which is about 12.5miles. (testing on flat surface running non-stop).

It depends on what you are charging..it will fully charge a 2150 mah in about 90 minutes. Hope that helps.

A brand new battery can take up to 3 hours to fully charge. After the battery has been charged and depleted to under 5% about ten times, the charge that is held takes about 2 - 2.5 hours to fully charge.

probably a couple of hours if substantially discharged. The batteries I'm charging are not totally discharged - I just top them off every couple of weeks to keep them fully charged and it takes 15 - 30 min.

To fully charge the battery when it has no battery left at all, it takes about 2 hours to get fully charged.

A fully discharged battery will typically take between 20-30 min to recharge fully in my experience. Longer if the battery is hot when it is placed on the charger.

At FULL Charge, mine lasts about 15 to 20 minutes. It takes about an hour for recharging with the USB cable for your computer

ON a full charge with a new battery, between 5 and 6 minutes. Takes about 20 minutes to recharge.

Put the battery in your phone and charge it until the phone indicates that the battery is fully charged. Probably a couple of hours. The charge level can be viewed even when your phone is off.

Depends on how much is left in the battery. I just let it charge overnight, I have never timed the charge, but I would assume at least 4 hours from a full discharge.

From what I read it takes about 4 full hours... another way to tell if unit is fully charged is to look at light on the plug. When you first plug charger in it will turn from green to red, then will be green after it is fully charged. Just make sure to do as the instructions say and not leave charger plugged in for more than 24 hours.

If the battery is 1/4 full, and if you charge it at rate of 2.2 amps, it will take roughly 40 to 45 minutes.

I've never had it take more than 3 hours from completely empty, but it depends on what you're charging it with. As for how long it holds the charge, mine has held a charge for a couple weeks and any loss in capacity was not apparent to me. It may hold it longer than that, but I have used it so frequently that it has never been left alone longer than that. Make sure you charge it fully before first use, the longer the better for that. I believe the other answer was either a defective product or not fully charged the first time, because of how fast they lose the charge and how short their charging time is.

Like half an hour. If the light under the powerbank is no longer there then it means its already fully charged. Hope this will help
