Somebody who understands electronics, please: In use, this unit seems to power, but not charge, electronic devices. Why not?

Some problems I've had: the plug that goes into the car receptacle has a spring that is too strong and it pushes itself back out. Same problem with the plug on some accessories. Many cars do not power the the 12v port unless the key is in the "on" position. Unless the engine is running the power port will be close to 12v. That will operate many devices but maybe not charge them. With the engine running, the charge voltage should be very close to 13.8 volts. When one of your devices needs charged try again with the engine running. Be careful with how much amps or watts total is drawn (heaters, cookers, big lights, etc at the same time). Good luck! ...

Generally speaking it is a straight pass through. I use this with an ipod and phone chargers without problem. Occasionally I have to wiggle one to get it to firmly connect.

I purchased the same unit and I had the same difficulty. Connecting the unit to the power source, the indicator light shows power coming in. Might be an internal contact problem or a mechanical design problem, because anything connected to it was not charging. I had to press constantly the plug of the chargeable unit into the charger openings, but after a short time the contact got interrupted and I had to press again and again. Bottom line: not a good unit, I would not recommend it to anybody to purchase.

Is the red led power-on indicator lit?If so,your problem is most likely with the device.A volt-meter would help.

This is just a guess, but the device is digital. It is possibly not fully charged and so goes to the highest level it can maintain. As its power drains below what's needed for the highest level, it drops a level. If it is fully charged, it might be defective -- ours stays on for extended periods.

The power is charging the base. If you unplug it, I imagine it will work only until the battery runs down.

you don't plug devices into this unit. This is a "grid tied" unit designed to send power to the electrical gridIf you want an inverter to power devices this is not the unit you want

It looks like the batteries have to be removed to be charged (which makes me question why it's called 'rechargeable'?) The plug cord is removable and works fine - but only to power the unit directly. (as I understand it)

It could be defective, however with no information as to how it is connected, that would be impossible for me to determine. Try connecting the device to a different usb port on the computer. I have mine first connected to a "powered" usb hub and from there to a port on the back of my PC. That way batteries are charged regardless if the PC is on or not. In most cases if the device is plugged directly into the PC, power to the device is also turned off and not charging the battery when the PC is off. Hope this helps.......

It works while it's plugged in. I believe it charges - just slower - while it's being used. My unit currently is almost fully charged. Make sure you plug it in AFTER you have made a connection. Mine did not connect unless the charger cable was out. If it's plugged in when you turn it on, it will only charge.

Dear Customer, It could be battery activated. You may also connect it to 110v power directly. If you have further problem, please feel free to contact us.

Not sure how to answer this as I am not an expert myself. Its possible the power is not completely charged or the settings are not properly set.

I am soooo sorry, I do not even know what that means. I just plug it in and use it. Hope you find out your answer from someone else.

How could such a relatively sophisticated device not have such an obvious feature as an easy-to-use way to use the device while it's charging? Hadn't those geniuses thought about the user runnig out of battery power 1/2-way to a new/unknown destination? Geez...

Mine works just fine. This power cutting off thing is not normal. Return it asap!

I'd comtact the seller and get a refund or get them to give another device. Could be defective. Not sure but mine works. Could try unplugging and retrying. Or if your not using the correct power adapter to use that. Not much details on how you have it hooked up. Main thing here is to contact seller to find the best solution.

I have 3 Hard Drives plugged in and drawing amperage with no noticeable shift in power. I plug in my phone and my ipad to the same unit and they are both happy with that. I have to guess the outputs are regulated and adequate 1/2 an amp isn't a big draw!

That one stumped me too. Nothing in the instructions, although they do mention 12 VDC for that wire somewhere in a diagram. The instructions were horrible, and the thing never powered on. I returned it and got a refund. My suggestion is you do the same.

i wish i could help...my unit stopped working 3 weeks after purchase and has not worked for the past ~month. i will most likely throw it in the trash can. the manufacturer said they would send me a power adapter. i never recieved it. i am thinking twice about ordering anything from amazon as they appear to not care at all for their customers. it maybe time to revisit the brick and mortor stores. sorry for the venting. i wish could have helped
