Review: Does the job, so far! Read this, so you know what you're getting. - I was a bit skeptical of these after reading so other reviews, so I did a bit of testing. Hopefully my results will be helpful. My situation is that I am retired, have 2 vehicles and don't have a need to drive much. But it seemed like every time the weather turned bad, the 4WDs battery was dead, and every time it turned nice the rag-top was dead. Not only a pain to drag out a charger, but it's really bad for batteries to sit there dead. So I decided to get one of these and, if it worked out well, get a second so I didn't have to swap it between cars. After a couple months use and a bit of testing, here's what I can tell you: 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.
Review: Has kept my '01 Tacoma fully charged for over 2 years, driven once a month. - I have an '01 Tacoma V6 that is driven maybe once every month or so. It's parked outside, so I needed something solar to keep it charged. I was a bit skeptical at first, but this little panel has kept the battery fully topped up. Cranks right up without skipping a beat. Very impressed, and just can't beat the price! Update: after over 2 years, the solar panel itself starting coming apart at the seams and basically disintegrated with tons of little fibers all over the place (still worked though!). This is with minimal movement; the truck sits parked and is rarely driven, so this was definitely because of sun damage. I tried a few different chargers, but ended up coming back to this one. A viable LED function is what a lot of the other replacements were missing, and it was always guess work to determine if the battery was actually receiving a charge. This one has an LED at the plug location that will only light if the connection is properly secured AND the panel is receiving light.

## Questions & Answers

**Q: Will this unit regulate charging, so as to avoid over-charging a battery?**
A: So a lot of misinformation here...  this unit comes with a blocking diode built in to the unit (I have had one of these plugged into by van for about 10 years).  This blocking diode prevents the car from supplying current into the panel (like at night), which would result in slow discharge of your car battery.  You can leave this plugged in all the time (like for 10 years).  The person talking about the Schottky barrier diode has it wrong.  This type of diode has a lower forward drop voltage (less than half a traditional silicon diode).  And you DON'T put it between the two terminals...  in one direction it will short your panel and car battery (blow the fuse and probably fry the diode), if you put in the other direction it does NOTHING... it is in reverse bias, and essentially no current flows.  If you decide to put it in series with the charger, you will reduce the available charging voltage (and therefore the available  current) by about 0.3 volts.  The internal blocking diode is already doing this job.  If there is someone out there that has the problem of discharging the car batter overnight, you either have a bad battery or your solar panel blocking diode is shorted (not working).

**Q: I don't understand what good it is in lighter socket if car must be running. When running, battery charges anyway! What am I missing?**
A: You're right.  MOST cars don't power the cigarette lighter unless the key is on.  So if the key is off your solar battery is not connected.  That's why they give you battery clips so you can clip the PVP (PhotoVoltaic Panel) directly to the battery.  You could hard wire a socket directly to the battery if you like.  GO to a junk yard and scrap out an old lighter port from an older car and wire it in.  Since this panel is a mere 300 mA (0.3 amps) you don't need heavy gauge wire.  But you DO need to be sure you don't short out the wire on some sharp metal surface.

**Q: Why would you use an 18V charger for a 12V battery. It seems to me this would be too much voltage.**
A: Solar panels can put out any voltage, up to some maximum "open circuit voltage". If you put the panel in the sun, and measured the voltage across the leads without connecting it to anything, you would measure 18v, which is the open circuit voltage.Solar panels also have some voltage at which they will generate maximum power, this is the "Max Power Point", hopefully this is about 12v for this panel.The solar panel will match the voltage of any battery that you connect it to, but if the battery voltage is above the "open circuit voltage" (18v), it will not generate any electricity, and will not charge the battery.Ignore the other answers here, they are not accurate.

**Q: What size is the female barrel plug?**
A: The size from the actual solar unit is 5.5 x 2.5.  80w panel

*by G***K on March 3, 2017*

The panel puts out the rated power. However, I have several vehicles, none of which have an active cigarette lighter plug when the ignition switch is not left in the accessory position. So, while leaving the car for a prolonged period in an unsecured area, I'm supposed to leave the key in the ignition? Therefore I use the short cord with the clips to attach directly to the battery. The charger worked well then, but the cord is way too short. My suggestion to Allpowers is: (1) Provide a longer cord to attach directly to the battery for those many customers who need to do that. The cord-to-cord connectors they use, would work perfectly to disconnect the panel and its longer cord from the short cord left attached to the battery. Do not use a cigarette plug or connector anywhere. (2) If a cigarette lighter plug is still to be provided, delete the problematic LED light, altogether. (3) Change the panel housing from fabric to plastic and make the unit waterproof, in case one forgets to disconnect and bring the panel in when it rains. Otherwise the panel puts out even more power than another I have used for years.
