Charge it all you want. It will never work! It's a rip off. It doesn't charge my phone, it drains it.

Let it charge for 8 to 12 hours. It charges slow at first this helps the battery live longer. you want long term battery health let it charge 100 percent. Then it should be good. I love mine!

Plug it in and charge it. The charge just disappears with no use. After it charges for a time the front screen will come up and tell you the charging %. It will take a day to fully recharge.

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

I know this sounds stupid but make sure the battery is inserted properly and that it is in all the way. My charge time has been 10-20 minutes. My original battery charge lasted 6 months.

I agree with the other two answers, I had to charge mine for a few hours with USB cable provided before it would work.

Put it on charge for twenty four hours. You may even have to keep it on charge I have to keep mime on charge or it won't come or stay on.

If you plug it into a computer that is on, not in sleep mode, it should start charging right away. No tricks.

A charged battery should power your machine for at least four hours so if your battery is inserted correctly, it should give you at least 4 hrs before charge is needed. If this is not the case, your battery may be defective. Do you see if the computer is actually acknowledging the battery under "power management? Hope this helps..

I supposed it will charge it if it works. My unit did not get charged nor did it charge anything.

BEFORE USE, let it charge all the way to get maximum efficiency. I charged mine for 8 hours to get a full charge. One must be patient to reap the rewards.

It takes about 30 minutes to charge. It will usually stay charges for around four hours.

Looks like it's not working. I had mine a long time ago and i know i charged it like for hours. Maybe 8. But not 2 days. That's too long. If it's still not charged, then i would think it is not functional.

you have to do initial charge for like four or six hours. You can use any usb outlet. if you have problems with your item make sure you get teh serial number and contact the help line on the j lab site.

I'd give it a few hours plugged in time to charge the battery. If that doesn't work, I suppose it's defective.

I didn't get a chance to find out because it didn't work properly to begin with, and so I returned it. It took maybe 4 or 5 hours to charge completely which is what your suppoosed to do before you use it for the first time.

On the manual, it states you should charge it for 4-6 hours, but I was able to get full charge within 3 hours.
