Harbor Freight portable solar battery charger item 68690 Video Clips. Duration : 5.22 Mins.
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.

Part 1 Click here for part 2: (READ MORE) www.youtube.com www.driverstorer.com DS tests the Harbor Freight 1.5 watt amorphous solar panel- solar battery charger kit. Chicago Electric Power Systems Article link: www.driverstorer.com For use with auto, marine, ATV, and other trickle charge applications Don't forget to hit subscribe! DS briefly runs through a series of current and voltage tests on the Harbor Freight 1.5 amorphous watt solar battery charger kit. The harbor freight amorphous solar battery charger kit includes: *One mountable solar panel with hard plastic bezel measuring 14-3/4" L x 6-1/2" W x 7/8" thick *Detachable vehicle adapter with activity LED (12V) *Documentation Formulas used to calculate the wattage from the solar panel: Variables: V=Voltage I=Current R= Resistance W= Watts V=IR (ohms law) (to double check calculations) W=(I^2) R (reads: (watts = current squared * resistance)) Current measured (100 ohm resistor in series) 25 -- 35 mA Output wattage calculated in overcast skies (100 ohm resistor)= W@ 25mA= 0.0625 (62.5mW) W@ 35mA=0.1225 (122.5mW) W@ 120mA= 1.44 Assuming you reach the advertised max current from the solar panel of 120mA you seem to max out at 1.44 watts theoretically. This is close to the 1.5 watt rating of the solar panel, but slightly less. As a vehicle battery trickle charger, the Harbor Freight 1.5 watt amorphous solar panel- solar battery charger kit will work as advertised, however local conditions will always affect the efficiency ...
