usually takes about 3-4 hours but it depends if you let the battery drain all the way or recharge it when it has half charge. I have not recharged it for awhile and I have use it to restart cars, inflate bikes tires and inflate sport gear these past months. I do check the battery meter to see how it's holding and recommend to keep on a shelf above the ground and recharge at least every month if you use it often other wise it holds charge without recharging that much.

It depends on how low the battery level is. If you are charging it from 0 then it will take about 1.5-2 hours.

When I received mine, it was charged. It usually takes a couple of hours to charge it up.

Hi Robert, I don't remember exactly how long it took to charge, but I have had mine for over a year now and haven't had to recharge yet. I don't use it a lot, but it's ready when I need it.

Sorry I'm not sure maybe an hour. Since I've had I have not needed to charge it again.

depends on your rate of charge. But if you charge at 5.3 probably about 45 minutes.

I have used it for 6 hours, and it still had a charge. Don't know average, I charge it after use.

Nope it only takes about 30 mins to charge. I normally charge it while I'm sitting at work!

I don't know exactly how long to charge, I usually plug it in at night and let it charge overnight. However, I would definitely buy a back-up to have ready.

How long you have to charge it depends on the charger you are using. I use a wall plug charger and I would give it at least 8 hours for a full charge. On a computer, I would say at least all night or more. I have had mine in my locker at work for weeks and it never lost it's charge and still charged my phone.

it takes a long time, im not really sure because i usually charge it with the adapter it came with, but if i had to guess i would say around 16 hours or longer.

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've charged it once since purchace. Unsure as to length of charge as I turn it off and on frequently. Takes around 40 mins.to recharge.

Not long. 20-30 minutes max. Mine came with an extra battery, which makes it use able. You always have to have a spare charged. Other than battery life, it works great.

6-7 hours or so for me - do yourself a favor and purchase a longer usb cable so you can charge while using when necessary.

I don't remember how long it took to charge but you can use it while plugged in since it is battery or direct current. I stopped using mine since it did not work properly.
