How long does the device hold its charge? If I leave it in the car for emergencies, how often I will need to take it out to charge?

I'm a flight attendant and carry mine with me at all times. I've had mine for 6 months and it still shows a full charge.You push the power button and the lights will light up to show power remaining.

This is a waste of money. It didn't hold a charge or even charge all the way when plugged in. I was able to recharge my cell phone maybe one good time. certainly does not live up to the claims made.

Ive had it plugged in to the wall and car while in use and havent experienced the battery life shortened. The only thing I have noticed is the volume is not as loud when it is not well charged.

I have had no issues with my unit. I use it daily for phone calls and listening to music through my phone. I have forgotten to switch it off when getting out of the car, leaving it on overnight numerous times, and it still maintains plenty of charge. I haven't actually tried playing music from the radio in the car so I can't address that. I've had this for several months now and honestly have only plugged it into the charger 3 or 4 times. I'm super impressed with this product. Sounds like you received a bad one and need to exchange it for a new one.

It actually last awhile on a full charge. I've had mine last as little as a 10 days to lasting a full month and longer, depending on how much you use it. I was going to test out the using it while charging, but I seem to have misplaced the cord. This charge is still going from around 3 weeks or so ago. Give me 2 weeks and I tend to start losing things.Give me 2 weeks and I tend to start losing things. I'll find it and post back.

You can keep it plugged in all the time and you won't damage it. I think it takes at least 20 hours to fully charge it, after it's been totally drained of it's power.

If you charge it for 12 hours it will hold a charge for 3 months but its best to charge it every 3 month 2 to 3 hours . I hope I answered your question good luck .

It's my boyfriend's but when he charges it takes a couple of hours like 3. If exposed to too much heat or cold it can die within hours, like 2. If it is happy then it can hold a charge for days. On day two of being in his car he plugged in his phone and had 30 minutes of extra power. Which was a big deal that day.

The manuals for these typically say "Recharge after each use as well as at least once a month even if not used". I've had a similar one for 10 years and by following that it still works well. Beware that if this is cold from being kept in the car, it will perform much poorer than being brought out of a warm building (yet it may still help enough to get you going).

This is a great unit. Be sure to give it a full initial charge! After that, you can carry it in your automobile for up to 60 days before recharging. However; be sure to charge it AFTER EACH USE. Also, there is a neat little button on the unit's face that indicate any need for a charge.

I would like to know same: if used with car battery that is in the car (not taken out), does the car need to be running????????? Also, does anyone have an estimate of time it would take to charge?

Hello, the device built in a rechargeable battery, but need to charging the device when you use it. The battery just can be used in emergency.

It's rechargeable - it has lithium ion batteries so it's not too heavy. You can either plug it in to a wall outlet or charge it with your car's battery - once the car is restarted, of course. There's also a flashlight included.

It does not last more than two hours with out needing to be charged. if you do get one get a either a car charger or an extra main charger to carry with you. It can be a night mare trying to keep the phone charged. I hope i have helped you with you answer.

I had it running over 2 hours on a car drive once and it still was holding a charge. It got very hot towards the end. Hope that helps.

The end that charges the item has to be plugged into a USB receiver. Either a PC or an iPhone plug that plugs into the wall. To add to my last review... I must say that after re-charging it and using it a few times, it seems to be holding a charge way longer then the first time, making it more handy to have for emergencies! I'm considering purchasing another for my teenager. Hope this helps!

I don't really have to charge mine too often... I'd say between 150-200 tests between charges (I'm not exactly keeping count haha!). I probably charge it less than once a month. Similarly, I haven't really kept track of how long it takes to charge, as I usually just plug it in and leave it overnight, but I can't imagine it takes longer than a couple hours to fully charge? Maybe someone can provide some more exact answers, but hopefully this helps a bit. By the way, this thing is awesome. Highly recommended.

I haven't had any problems with it holding a charge. I have noticed if I don't use it for a few days it doesn't work. So I would suggest charging it every other day or so. If mine is charged it usually lasts a couple hours.
