How long do I have to charge it the first time?

A couple hours should do the job. When all 4 lights are on and no longer blinking or moving, you know you are fully charged. At this time you may begin using your Sherlock Hones portable battery charger. When you want to know how much "charge" is available, touch the little hand on the front and the lights will tell you. 4 = 100%, 3 = 75%, 2 = 50%, 1 = 25%. When you have 1 light, it's time to think about recharging the portable charger so you'll be ready to go with plenty of "juice" when you are out and about.

I am not sure of the official answer, but I charged mine overnight. It has been working great!

It recharged from 50% to 100% using my car's 12V outlet while driving for about 1 hour

As per the instructions you charge it for 12 hours then totally drain the battery 10 to 12 times. Not do it once. It has to do with battery memory. Also use a full 110 wall charger for charging and not a weak USB port to charge.

2 hours, then charge it again, the first two times let it charge for 12 hours, after that 1-2 hours..

It needs to be charged a full 24 hours when you first get it. If you charge it less than that the first time, the charges won't last as long. A battery can have a memory. If you charge it a short time, you will only be able to use it for short times. Be patient and charge it for 24 hours first, after that keep it in the stand and it will stay charged. In my kit there's a bright yellow taped instruction on the box that held the charging base where it says to charge it a full 24 hours before using the first time or the warranty is void.

First time on a new battery about 4-6 hrs...after that about 1.5-2 hrs. Depends on the age of your battery.

I never charged mine when I first got it and after at least a month of using it during my college classes, I just had to charge it for the first time.

Yes, charge it before using it for the first time. Yes, charging it overnight should be enough.

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

You need to charge it for 18 hours for the first time and then after that 14 hours at a time but no more than 30 hours at once.

We charged for 8 hours before the first use. After that, charging only took 2-4 hours.

The initial charging time is 24 hours. Let it charge for 24 hours before you use it.

Before the first use it needs to charge for approximately 48 hours to prime the battery for future use. After the initial charge plug it in over night and it is ready in the morning; usually 6 to 8 hours. It has indicator lights that will let you know when it is fully charged. When all three lights are illuminated it has a complete charge.

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.

You just plug it into an electrical outlet. First charge takes abour 36 hours, then you're good to go.

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.
