What is the output voltage of the AC charger? I want to design a solar panel and charger for the battery pack.

Look on the adapter and it will tell you...I believe it is about 20 volts...you could definitely make a solar charger...the other option, one I use, is to use a 12V to 120 adapter and then can plug any 120v appliance in to the standard outlet...obviously within the wattage of the solar panel and adapter...and it will exhibit some loss...typically about 20%

My AC adapter came with output of 20V and 2A . Specifications of the power bank says any AC adapter voltage between 15V and 24V should be okay. I have tried an old laptop charger with 19V and it was fine.

You would find that the output would drop to zero by 22V. I have one connected to a big 24 volt battery rather than a panel directly, and the output varies from around 430 watts at 28 volts (the peak voltage when charging) and drops to 220 watts at night when the battery is around 24v at night. The 600 watts is a peak for when panels give high voltages.

the output voltage should be 4.2V and output current 300 mA. if you look carefully at the picture you can read this, but it is wrong in the product description. the 12V refers to the car charger input voltage. why 4.2V for a 3.7V battery? it is common for chargers to be at a higher voltage than the battery it is charging. there are sensors that detect what voltage the battery is at and once the battery is close to charged the charger lowers the current applied to ensure that the battery is charged thoroughly and quickly.

The box says the solar panel outputs 5.0v / 70mA and the unit itself (battery pak) will output 5.0v / 500mA. Size 3.0" wide (stretched) 5.5" tall, 0.7 thick.

Yes, gives voltage for solar output, both voltage and amps when battery mode is selected. I have nothing connected to the load terminal.

All 4 of my chargers are set for 4.2v. I have had NO problems at that setting But, always charge new batteries as soon as you get them. I charge all my batteries, any size in it. The charger is automatic , stops charging at the correct voltage. George

I'm assuming that by AC charger, you are referring to the transformer. If so, you need a transformer that the output is 12V and 1.0Amp. The trick is the adapter that plugs in to the base charger. My advise it to purchase a Maha PowerEx MH-C401FS4AA27 - Battery charger - battery - rechargeable - AA x 4 - 2700 mAh. You will also get the DC and AC adapters. The difference in the price is just a few dollars.

AC Battery Charger, Model HR05NS033 input 100-240 VAC 0.3A 50/60HZ Output 4.2V 600mA

Do you mean your solar panel puts out 18 Watts or 18 Volts? The 10 Amp Solar Charge Controller is designed to charge 12 Volt Deep Cycle Batteries. If you only have a 18 Watt Solar Panel recommend upgrading to a larger panel.

The plug-in charger only puts out 2 amps. If your solar panel USB port has similar output there should not be a problem.

Hi Jennifer, the panel that came with the kit is a UL SOLAR panel...it is 30 watts 12 volt polycrystalline with the ac plug wire already attched. I tested the unit. Ran down to 20% and attached panel. Recharged in 7 hours.

solar array voltage normal input of 17 to 22 volts maximum of 25 max charge is 30 amps i hope this helps you i have mine hooked to 3 15 watt cells and it is charging very nicely

The AC Adapter is a two prong that plugs into 100 to 240 V at 50/60hz 0.60A Max and it outputs to the charging dock 12Volts at 2 Amps. It is a model NLD200120W1U The ChargeIt is a model 08803 and its input from the AC Adapter is 12V at 2A

Short answer is NO. The output from this unit's USB port is limited to 5V 500mA, or 2.5W. A typical laptop AC charger is around 19V 6A, or over 100W. You cannot charge a laptop through its USB port, anyway.

Theoretically, in ideal sun conditions, your max amp output would be 40A. The adapter would parallel those 4 individual 10A panels together, but it would be up to your charge controller to determine the actual voltage and amperage supplied to the batteries and act as the brain and prevent overcharge.

Looking at mine, the charger is an ac/dc charger 120 v 60 htz, 12 vdc 650 ma. Positive center.

I'm no Electrical Engineer, but this is what I have to offer: The charger I have is a Worx WA3737. The specifications for the charger are: Input: AC 100V-120V, 50/60 Hz, 1.5A. Output: 24V, 1.5A. Output DC barrel jack: Polarity = positive (outside = neg, inside = pos.) If your solar array can match the input specs for the charger, which I suspect you can't, you have no problem. On the other hand, if your solar generator can match the output specs for the charger, you should be able to charge the battery by some means other than the OEM charger, but the OEM charger may have components that protect the battery against overcharging, shorting, etc. In other words, you would have to have someone with knowledge of electronics crack open the supplied charger to see the circuitry and use/match that configuration for your new charger which is built for input from your solar generator. Of course, this would probably void the warranty, and should be done only by someone with a knowledge of electronics. Hope this helps.
