can i use electric source to charge the device or only solar power

This power pack stores about 23 amps. The pack contains a power cord to charge the unit. It takes about 3 hours to fully charge from a depleted state. The solar function is only a trickle charger. However, Do Not Leave It in direct sunlight. In summary, a good, universal power pack.

Yes, you can and actually you have to use electric source at the first time to charge it. And be advised, if you just use solar power, you can jus charge about 75% not anymore, to charge 'till 100% you have to use a elecric source.

The short answer is no, however with additional controllers, inverters, breakers and fuses any power sources can be combined. Wind, Solar, Hydro electric, even thermal. When combining these power sources to charge batteries it is best to have the experts design a system that will work for your specific application. This will save you money in the end.

It's doubtful. Most of the emergency solar chargers only provide small amounts of "emergency output". I have a Sony tablet that requires 5v 2amps, take into account the radio uses 3 AA 1.2/1.5 (3.6v/4.5v), it won't provide enough power to charge a power hungry tablet, maybe just a small phone and only for a few minutes.

yes, just connect the solar charger to the battery whenever you want to charge the battery.

It is according to what you use for your power supply !! I Use A 12 v-dc Battery And a 12 v-dc Solar Panel To Keep The Battery Charged.12 V + In 12 V + Out / 12 V - In 12 V - Out. so your answer is (YES)

Sure, but you will want to make sure that you have the solar panel hooked up through a contoller/regulator to avoid overcharging the battery. This is true with any battery.

you can connect it to an appliance only if the appliance uses the same voltage as the solar panel. The most complete system would include a controller the regulate the voltage from the solar panel, batteries to store the energy produced so you have energy when there is no sun, and an inverter to convert the energy from the direct current (AC) that the battery uses to alternating current (AC) that most small appliances use.

Mine works fine using the solar. I did notice the charge doesn't last long after the sun goes down though.

The panels do not hold a charge themselves. You can charge directly from the panels or connect an external battery (not included) and charge that as your future power source.

grid tie is solar only but if you have a battery back up you can use the wind turbine to charge your battery's. You will have to buy a Outback grid tie inverter.

It should be OK, so long as only you are only using the one charging source, in your case solar. If you choose to use both the vehicle charging system, and solar, I would add a switch to separate the two different charging systems.

Solar is nothing more than a battery charger. If you can operate your a/c unit without plugging in or using a genertor then yes you can.

No..... and maybe.... The point of using the controller is that with small loads less than the rated amperage, when the battery is fully charged, your load is being supplied with power from the solar (bypassing the battery). This allows the charge controller to float charge the battery and also power your device.... If you are drawing lots of power through an inverter, then yes, you will need to connect directly to the battery.... Just FYI - the unit I got had an UN-replaceable fuse.... I had to create a work around to solve the problem....

No it does not work on solar power you will need to charge it with the micro usb cable either plugged into your pc or any 5v power supply from your phone. Hope this helps

Unless you get a very expensive, sophisticated system, you will not be able to hook into the house electrical system. Most panels and windchargers produce 12 V DC. It has to be inverted to 120 V AC and still can't be connected to household power. For most of us it is best to just power certain things on solar and keep everything else on the grid.

The directions on box says to electrically charge it before using. Just guessing on my part - it would probably take a very long time if you do solar only.

Yes you can, however if you don't have a analog meter box from the power company it will only offset your immediate use during the day when the pv array is receiving sunlight. Your power company can install a meter box that will remember how much power your back-feeding to the grid, if your meter is digital, you should contact them first in that case. Analog meters will turn backwards if backfed.
