After the battery in my cell phone is fully charged from this device, can I leave it plugged into the battery pack for several hours without harm?

The answer is yes.Your phone is designed with software that never allows a full charge technically. Batteries last much longer if they are never fully emptied or never fully charged. When you see 100% on your battery icon it is really more like 90%. The software essentially "turns off" the charging even when the phone is still plugged in (like overnight for example).

Yes....And It does have an energy saving feature if there is no draw on it it automatically shuts off.

I have left my phone on it for hours while the phone was powered on but I have noticed when the phone is off and when it is done charging, the battery pack shuts down automatically so if your phone is off, my guess would be that it shouldn't. Not sure how it would be if the phone is on. Maybe it works the same as it detects the battery is fully charged it may shut off either way as to not overpower the phone.

The device will go into sleep mode but I am not sure if it is a good idea to leave it charging.

You can leave it plugged in if you wish. I usually unplug it after fully charged and let it sit. It keeps the charge for many weeks.

There is no need to worry about charging time. Just insert the battery into the charging station and when the battery is fully charged the charging stops. There is no harm done by leaving the battery in the charging station indefinitely

Yes you may. It seems will stop charging after fully charged.I have left the plug in for over 24 hours couple time, and everything is still in working order

Overnight and then I leave it in the charger all the time except for when I'm using it. You can't overcharge it.

A fully discharged battery will take 3-5 hours to fully charge. CAUTION! Recharging the battery pack for more than 5 hours can damage the battery cells. Place the battery pack on a dry, fireproof surface in a room that is between 50-104 degrees Fahrenheit. If re-charging a newly spent battery pack, allow to cool completely before charging. More information can be found on page 7 of the user manual which you can read from this link: http://manuals.harborfreight.com/manuals/68000-68999/68239.pdf

I don't think so. I've left mine plugged for more than 24 hours and it was fine!

No, don't leave it plugged in. It will drain the battery. The green light is cool but it drains the battery slowly but surely.

Leaving the charger plugged into the wall is fine so long as the connector end is kept safe from water, pinching etc. You should not leave the device plugged in all the time as this is not so good for the battery. If you never plan to run the device on the battery, you are probably safe leaving it charge all the time.

No problem to leave on charge a day or so, but overnight is MORE than sufficient. I would not purposely leave on charge for more than 8 hours, but doing so every once in awhile is fine. I purchased additional batteries, BUT I bought those with even more power for better life.

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.

Probably not. I have not tested it that way but I left mine unplugged, did not use it for 4 days and it was almost dead when I tried to use it. However it does recharge really fast. I plugged it in and an hour later it seem to have a full charge. I use this little device daily so I just leave it plugged in. Maybe just plug it in an hour before you need it and use it that way.

I leave mine plugged in to the car charger all the time. I can not speak to removing the battery, since I believe it is sealed. But it works great for streaming the music apps on my phone.

Just FYI, it doesn't damage your iPhone to leave it plugged in when it is full. It knows when the battery is full, and stops charging it. So no damage to battery.

Store your batteries fully charged. Also, try to avoid letting lithium ion batteries (like the ones in cell phones) discharge completely after the initial 4-5 cycle "break in" period.. Repeatedly draining them all the way can shorten battery life. Most battery chargers have a protection circuit built in so leaving a battery in the charger past the time it is fully charged will not harm it.

You can leave the batteries on the charger to no detriment.I've left mine on for days, even. Do disconnect them if it stays in "charging" for entirely too long (I'd say over 24 hours) as that might blow your batteries up. I've never seen this though.
