A Thunderbolt Magnum Solar portable household battery charger demonstrated. The unit was purchased from Harbor Freight. The item number is 68690. This is a good backup charger if your main power is off for a long time.
In this video, I take a Harbor Freight 1.5 Watt Solar Battery Charger and show you how to take it apart and cut out the LED so the voltage is stady instead of pulsing with the LED.
I like to thank other users for their similar videos so thanks to

This happened when trying to use the charger for the second time. WARNING! This charger is clearly of questionable quality. If you must use it, place it well away from anything that could catch fire. I was extremely lucky to be in the garage when the charger first did this. I had carelessly placed it within about a foot of a gallon of model airplane fuel. If I had left it unattended and the charger had burst into flames, I am quite certain my I would be homeless right now.
UPDATE: One of the diodes was burnt out. That’s what was causing the problem. I went to RadioShack and bought a 25A 50V rectifier to replace the diodes. Surprisingly, the charger works fine again! I would suggest using 2 of the RadioShack rectifiers in parallel just to be safe. This should make the charger far less likely to self destruct in 55A jumpstart mode.

The solar panel conveniently plugs into your car’s 12 volt cigarette lighter. This solar battery trickle charger is the eco-friendly way to maintain the charge of any car, truck, marine or RV 12 volt battery. Good for survival and prepping.
Testing the Second Failed Harbor Freight Item #60581
I could not find a video on this, so, I made one real quick, while I was super pissed off, that the SECOND charger I received was no better than the first… Here is how you can test them.. I didn’t see anyone else who had done a video on this, and it needs to be out there, as lousy a video as it was.. Grrr… But, it will help if you need it.
NOTE: If you are not pretty sure that your Boost is not working, maybe you should not do this test on boost with a 10 amp setting.. Might blow a fuse or burn out your $5.00 meter..
I made this video for Harbor Freight, when I wanted to send the 3rd unit back in for a refund, rather than swap it out for another one..
I bought a Die Hard 200 amp boost roll around charger.. Best charger I have ever had and makes quick work out of the dual Bus Batteries I have to charge and jump from time to time..
Inside the box we see the reason it cannot supply 50A and cuts out. Has a Bussmann 20A self resetting circuit breaker. I also explore modifying circuit to have a switch to force voltage at clamps. This experiment did not go well. as even if I jumpered the AC relay and forced power to the transformer the regulator circuit would still not power on.
$13 Harbor Freight Solar Battery Charger. The freakin thing WORKS!!
Tests of output volts and amps produced before and after removing the blinking LED. Both overcast sky and bright sunshine. I hook up a DC to DC Buck Converter and explain it a bit. I run a USB charging port, I charge a camera and a cell phone. I use the panel to make a batch of colloidal silver. I test the panel with a simple solar charge controller. I charge a 12v- 3ah lead acid battery. This solar panel is not weather proof because it’s designed to be used on the dash of an enclosed vehicle.

Be sure to read the reviews to get a more well rounded understanding of this product.
Is Harbor Freight casting aside brands like Chicago Electric and Cen Tech? What will become of Drill Master? These are my thoughts on the matter.
