By the lights on the device when they stop blinking it is full charged and the number of lights lit will decrease as it discharges or used.

The blue lights will blink until all four are steady lit. When you use it to charge a device the lights will go from four to three to two to one.

That's how it is. When it charging it does not stay on to let u know that it's charging.

You would have to use a battery tester or a voltmeter whcih will tell you if there is still a charge on the battery

The light is supposed to be lit when charging. It might have a faulty or loose bulb. If it charges, I wouldn't worry about the light.

I have not used the one I have in some time as the connection used to charge it broke on the 4th use. Having said that, I believe that when you plug it in there is a red light showing it is charging; when it's done it turns green. Good luck!

No battery charge indicator. Not even an indicator to let you know the charging is complete. All it has is a blinking led telling you it is charging, but it never stops blinking!

I'm not sure cause I usually have it plugged into my car via usb2.0. So its always being charged

its really hard to read the lights to tell if its charging. I tried it a week ago and as far as i could tell it was charging and charging my phone at the same time. it just seemed a lot slower charging.

When you plug in the battery the little green light will come on to let you know it's charging. When that light has turned off then the battery is fully charged and you can put a new one in.

I only know that i need to charge it when it stops playing music, but it can be in the on or off position to charge, i prefer the off position though because it charges faster. there is no indicator for it charging however.

I think it tells you if the unit is charged [green light] or not [red] but I can't test mine right now because it is charged.

I've charged it while I have something plugged into it. I don't know 100% that it was actually charging the Jackery, but it charged my devices.

there should be a data plate sticker on your unit that tells you what it was charged with

I think that means it needs to be charged. Plug in the usb to charge the speaker and see if it later turns green.

There is no way to know when it is totally charged. I just charged it up overnight and it held a charge for a long time.

On the bottom of the desription about the item it should tell you that it charges your device, hope it helps you with your question
