Alligator Clip use the red and black battery clamps to trickle charge and maintain 12 V battery, make sure they connect correctly.
Cigarette Lighter Scoket

(1)Remaining power of your battery is no less than 60% before attaching it
(2)This item is just battery maintainer, keep a battery topped off
(3)Make sure a “live” lighter socket: the socket gets power at all times from the battery, you can test this by plugging in a phone charger or other accessory with the ignition off--if the accessory turns on, that means the socket is "on" at all times.
(4)For modern vehicles, there are body control modules (computers), alarm systems, immobilizers and lock monitoring. All of these units will rob electricity from the battery when it is not in use. Also, cars batteries naturally discharge itself when not in use. For such cases, it is suggested to leave the battery charger connected with batteries for the whole off-season to offset the nature loss, but for vehicles outside the garage, an off-gird solar battery maintainer may be the best choice.

1) Don't expect this to charge a dead battery. Not designed to, and won't. What it will do is offset the natural loss in the battery and the minimal drain that the vehicle may have when off due to such things as the computer, security system, etc. There is an isolation diode contained within the solar panel to prevent back-feed drain regardless of whether the lighter or clip-on cable is used.
2) The Red LED on the lighter plug is your friend, if you know how to use it.
a) Connect lighter plug to solar panel, but do not plug into lighter socket. Aim panel towards sun and observe that LED lights,
then aim away from sun and it goes out. This proves that the panel is generating electricity.
b) Disconnect lighter plug from solar panel and plug into lighter socket, with ignition off. Verify that LED lights. This proves that socket is live
with key off.
c) Connect lighter cord to panel, and install panel either on the dash, windshield or (my preference) on the passenger's visor which can be
rotated to catch the best sun based on how you park. Protect the panel from the elements; this is not an outdoor panel.
3) Do NOT disconnect when driving, just rotate so it does not impede your visibility. The isolation diode will protect the panel and vehicle from
each other regardless of whether the car is running or not. Frequently plugging and unplugging the lighter socket increases the chances of
a bad connection inside the socket. If you must disconnect, do so at the panel end instead, and make sure the LED is on before
reconnecting. If it ever seems as though it has failed, repeat the tests in step 2 above.
If you do the above, I think you'll find this does what you need it to, and does it well. Hopefully this fills in the gaps in the manual, as well.
Update: The seller has contacted me and has assured me that this is a problem that they are trying to fix with the cloth, it seems to be related to the temperature. They have been courteous and prompt while trying to resolve my problem.
I have upgraded the star review because of how concerned they are about my experience.
This can sit, or clip on about anywhere on the vehicle. It comes with elastic bands and fits on the sun visor, where you can flip it down when you're using it, and up when you're driving. It has clamps to hook to the battery (like on the mower) and a power plug (cigarette lighter) cord to use in the car.
I've used these for years on my lawn equipment over the winter, and on my second vehicles I rarely drive. I bought the grandson a 2002 Ranger truck for the big 16, and gave him one of these to help prevent battery drain. I think they are great.

Can be hooked up via car charger cigarette lighter plug or battery charging clips, both cables are supplied and measure 1.5 meters/5 ft.
An LED light indicates charging.
So far I've tested this on my riding mower and boat batteries, I verified before and after charges with a metered charger, and this charger definitely added "juice" to the batteries. I plan on using this for maintaining my batteries over winter (unit will be mounted on a south facing window). This would also be great for vehicles that sit for a prolonged period of time.
