Does the USB charger charge from battery power, or does it only work when plugged into an outlet? This seems ideal for emergency situations.

Hi Ashley, A battery charger with an auxiliary power supply is a great idea, but the Tenergy T-9688 will only power up your batteries when plugged into an ac outlet. An easy solution might be to purchase a mobile charger with a car adapter that plugs it into your car's cigarette lighter socket. Amazon carries them Hopefully you won't have any emergency situations.

I agree that this will good in emergency situation. I don't have it yet, but if we had full batteries, It could use for charge our mobile device. And for power supply, we could buy a solar panel that has that kind of jack plug. Let try! I think I will order it.

Hi, Ashley. I've owned the sister unit to this, the Tenergy TN190, which works just fine from a car's cigarette lighter socked. All you need is the proper accessory from Tenergy. One end of the cable plugs into the cigarette lighter, the other into the side of the charger. I'm sure the T-9688 works this way, too.

Hi Ashley, just to be clear, the unit only charges batteries when plugged into the wall outlet. Also one thing that might not be apparent is the fact that while you can charge electronics using the USB charger, it does NOT charge them while you are charging anything else. If you are charging a few AA batteries and plug a cell phone into the USB plug, the unit will wait until the AA batteries are charged BEFORE it will charge the cell phone plugged into the USB port. Keep in mind, you can charge something through the USB port while batteries are discharging. However, once the batteries are done discharging, the USB charging port will shut off when the batteries start to charge. Hope this helps.

This is not a battery charger. It is a surge protector. It is placed in between the power box and the electrical cord that connects to the RV. It operates as a protection to the RV such that, when the power source varies beyond the pre-set limits, it stops the transmission of electricity to the RV(or whatever is connected to it). When the power source is stabilized the surge protector will allow the re-transmission of electricity after a countdown of 1 minute. It is incredibly useful for protection to the electrical circuity of the RV, especially when the source of power is unstable.

No, the USB charges the battery and it won't work w/o battery. Although you can work with it while charging, but it is recommended not to do so, to increase the life of your battery.

It works fine. I have no problem charging mine via a wall outlet..it's the only way I've charged it. Hope this helps!

No- I bought it because I thought it would charge an iPhone. It does not- so I returned it. And so far I have not found an emergency charger except a Lithium battery for about a $100 which you need electricity to charge it!!!!!!!!

It only works by being plugged into an outlet. It is not made for batteries.

Yes, it does plug into an outlet. This how it charges and doesn't use batteries. I took it on a trip for 5 days without the charger and it never lost power. I was a little worried that it would but, it didn't!!!

The battery charger comes with a charging cord that plugs into a USB outlet. You will need an adapter to plug into a wall outlet but you can charge it with your computer. I have plugged it into the car USB port and it charges fast and well. It is a great battery. I am currently traveling in Italy and have used it everyday.

I assume because it has an AC plug that this will work. Keep in mind it requires a lot of effort to get a charge so this device really is for emergency situations where you might need power rather than as a means to charge a device for the long term.

It does run off of AC power if you have plugged in the adapter to the wall and to the radio. And--you need to make sure it is sitting well inside the charging unit. If it is not placed properly in it (for example-not flat at the bottom--then the red charging light does not come on indicating it is not charging. Plus make sure you are turning on the ON button if you want to hear a report. It does not report the weather if it is not turned on. I hope this helps.

It is powered off the USB bus. I use an adapter plugged into 110 volts to insure constant adequate power (because some USBs have more power than others).

Battery: DC 4.35V, 350+50mA.USB: DC 5.2V, 800mA.Haven't tested the USB. The battery charger works well. Not sure on the speed. I haven't needed to charge one in a pinch. Usually leave it there and just get it the next day when I need it.

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 charge it with the usb. It doesn't last long. I am going to return it. Doesn't really work good if needed while out.

Not sure I can help with this. The charger does not have a USB -- if it is charging the battery pack then it is doing what it was designed to do. Of you unplug it after a charge and are using a USB cord to your device and it won't charge your device from any port, try a different USB cord to device as a process of elimination - I do not believe you should ever have to 'wiggle' a cord to get it to work properly.

I charge mine on the wall socket with a plug-in that accepts USB. Even though it doesn't recognize on your computer, you should see a lightening bolt where the battery is to indicate whether it is charging.

I just checked the instructions that came with the unit. It states that you can charge USB devices on AC or battery power but in order to save battery life the unit will cease charging external devices if being played on a high volume setting during battery operation. Hope that helps. ;)
