Does this unit have a connection for a load? Or does it only charge, and not send out current to connect a 3.7v device to?

I believe the board was made simply to regulate a charge to a battery. After the voltage reach 4.5 volts I believe what it stated, the board cuts power and switches to a standby mode

It's a 110v system so it connects right up to the power. Check your local codes before connections.

This unit generates a regulated 5V at its USB port. It has no idea what type of appliance you connect to it. It is up to your appliance (cell phone or tablet) to monitor its own internal battery status, and stop charging once its internal battery is full.The solar panel on this unit works, but very slowly. It is best to fully recharge its internal battery using an AC-to-USB adapter, then rely on the solar panel only as a trickle charge.

This unit needs to be connected to a battery and it will charge the battery. The amount of time will depend on the amp hours of the battery, how long you use you devices and how much power/amps they consume.

It's not a rechargeable device. It's need to be continuously connected to power supply.

Mine did not come with any sort of power connection other than a USB cable. Fortunately I already had a surge protector that also has 2 usb ports on it so I'm able to keep it charged at all times without connecting to my computer. (search "Belkin 3-Outlets Surge Suppressor with USB Charging" and you'll see it - the Belkin product has been 100% worth the price) You should know that I absolutely love this player and plan to purchase one for a family member for Christmas. Hope this helps!

It uses a power adapter. I'm not near the system, so I can't tell you what the voltage is right now.

Remember, this is a 4 amp unit. That means that any single device which needs less than 4A to charge, will be charged.... as long as that is the only device attached. If you have other devices attached, they will be drawing some current, usually up to 900 mA for a USB3 device... sooo something like an iPad may not be able to draw enough current. Most other devices should be ok.

Not sure what you mean. It's powered solely by the USB outlet you plug it into. If you want to charge something through it that needs serious voltage, you need to plug it into a high powered USB outlet.

That is the purpose of that unit. It is a battery charger AND maintainer.Mine has been connected for over 3 months.Andreas

It will charge any device that connect with USB and requires the voltage and amps as described in the ad for the charger. I used mine to power the magic jack.

It's not a charger per se - it is simply a passive adaptor. You could use it as a charger if you connect it to a source.

I have mine plugged into a PSU. This is likely the only way to receive power.

Yes, one is for data, the other is for power. Though it may be possible to use a USB charger for this connection. I have used the unit with a tablet by using a multi-port adapter.

The device operates on AA battery power but is supposed to draw power from a USB port that connects it to the PC. If an AC adapter is needed, I would look for a 3V universal adapter at Home Depot, Radio Shack, or Frye Electronics: take the unit in with you but save time by calling them over the phone ahead of going there..

No. It does not provide a connection any devices. It will however use POE if available which will eliminate the need for the power supply.

The unit has a Green Power Light when charging, also how much of a load do you have connected?
