Just a few days with this 5w version and thus far, I am pleased that it is working on my new vehicle. I drive very little and I have had one occasion where the malfunctioning lights from the sensors indicated a problem, but it turned out it could be a battery (weak) issue since I only drive 7 to 8 miles per week. at least that was the tech at the dealerships finding. A blocking diode ensures that the charger cannot flatten your battery and I cannot understand why very few individuals say it did. It hasn’t with mine. The manual clearly shows that this trickle charger is designed to top up battery from a natural drainage. It is not intended to charge a battery that has been fully discharge. 4 star rating instead of 5 for only a few days of use. If it works correctly after a few months, I’ll return here and update my review.

Short answer: Contrary to some of the negative reviews speaking about "warping", "discharging your battery" and other such things, it works exactly as advertised. I drive the test vehicle only a handful of times per year, so it sits outside for months on end sometimes which is bad for batteries, they like to be topped off all the time due to their internal chemistry. Long answer: I'm an Electrical Engineer so I did a few basic tests, with the following findings and some recommendations: NOTES: DO NOT leave the panel plugged in when starting or driving, spikes in the line might cause damage to the circuitry. It could fail and then put a load on the battery in that case. NO test for weather/water resistance was conducted, I have yet to test it in the winter time, which is a more challenging time for it and batteries too. I'm optimistic it will work ok given what I've seen so far. I tested this resting on the dashboard (no suction cups, I wouldn't trust that ever), with clear view of the sky facing generally slightly east of North during mid-late August, near the Washington DC area using a cigarette lighter connection with the supplied adapter. (it's FUSED, and works with a NEGATIVE ground socket/system, i.e. most everything not vintage) Some people have said the cig cable polarity is backwards, but in order to work as a CHARGER, the + connects to + as it should! Btw, the BLUE LED does NOT adversely effect the performance, and need not be "disabled" as some have claimed. The numbers I'm reporting are all with the unit as delivered, no modifications were made. 1) NO Battery discharge when dark (i.e., it doesn't drain your battery in the dark, or ever due to internal diode) Tested on the bench as well with a power supply and ammeter. 2) NO WARPING of case in direct sun 8hrs/day mid latitude US East Coast in August. (measured CABIN peak temps up to 117 deg, low of 69F, dash probably hotter in direct sun). ABS plastic has a glass transition temp (i.e. warping) around 105C (221F) so IF it is actually ABS, no melting/warping seems possible at temps found in cars NOT on fire lol! 3) For a HEALTHY battery, it MAINTAINS charge easily overcoming a parasitic drain in my vehicle of 9mA or (0.009Amps), and still puts a NET 44mA (0.044Amps) charging current INTO the battery in direct noon sun, and a NET positive charge current (in clouds/overcast), albeit only 7.3mA. In only 1 sunny day (and overnight) my new battery @ 12.34v went to 12.55v from this device. This is because it is a HEALTHY battery. The max open circuit voltage of the charger I measured around 22v but it can only deliver 1.5W max so you aren't going to hurt the battery with such low currents, and at best charging currents are only present up to about a 1/3 the time during a 24 hr period I'd estimate. NOTE: A dead/failing battery cannot be rescued by this or any charging device, and my prior failed battery at 12.24v (after 2 day commercial charge from "dead") with this same device under same summer conditions in 2 days went down to 12.01v and failed to turn over the engine! After the attempt it was down to 11.5v, clearly no good. I think this is suited as a MAINTAINER, don't bother thinking this will "charge" a vehicle battery. I drive that vehicle very very rarely, so this will keep the battery ready to go without having to periodically start it every few weeks to charge it up. Temperature and time will reduce the efficiency of the panel, but there is a 4x margin in my case (with a 9mA parasitic drain, which is quite small). If your car has a lot of electronic features, security systems etc, your parasitic drain could be more than this can even put out. In that case you would need a bigger higher power panel (this is only 1.5W). To measure the parasitic drain: with all vehicle doors shut, pull the main battery fuse and put an ammeter there, since it will measure absolutely everything, using any other fuse will only get a subset of what your battery drain is. Start with the maximum scale (typically 10A) to be safe, switch to smaller scales once you know the range. Let the initial connection settle since there will be a surge for a bit as all the electronics initialize and settle into a steady state. My vehicle settled in about 5 seconds (an after market CD player self test used 250mA during that 5 seconds) In principle, some sensors and other fancy stuff could spike some current periodically, but this couldn't be known without a logging ammeter. In all likelihood it won't boost the average drain in any significant way from your measured steady state.

I have had two of these types of panels in my Honda over the years. If not driving for a while, I open the sunroof shade and leave this on the dash plugged into cigarette lighter. Cold weather, alarm, and fan that sometimes run after engine is shutoff all put some kind of drain on the battery. This will noticeably extend battery charge when you don't use it for a while. The only thing I can recommend is to use it on a dashboard that is flush and flat. My first one was too big and fit too snug and somewhat warped and changed the shape of my dashboard. Lucky for me simply removing the over-sized panel and the UV rays popped it back into original shape again. The suction cups were not necessary for my vehicle as it always stayed in place even with emergency braking etc.

Great solar charger for the cost. For the first 6-9 months in the weather it works as designed but after about the 9 month mark the solar charger starts to loose the ability to push a full 4.5-5 watts. After about a year I was only seeing 1.75 watts. But for the price and the durability I have replaced them with the same brand every year. 4 years in a row and they are still my goto. The only manufacturing upgrade I could recommend is some type of sealer around the plastic and the top of the panel. Over time I believe water finds a way in and starts to cause issues with the board inside.

Purchased this to keep a sea doo that was on a lift and only periodically used, charged up. I hated dragging a charger and cord down to the water when I wanted to take the grandkids for a ride. This has performed great. It hasn’t failed me yet. I attached it to a 2 x 6 about a foot and a half long and just set it on the dock and can move it around. Comes with a cord that is a nice length. Bought a second for the boat this year.

I hate reviewing before we make sure the product is going to stand up to time and weather but so far so good. A few weeks have passed.

I was using this for my golf cart where I live on a small island and it is very helpful, I was using the solar charger as directed as it states it can be left outside is waterproof and weatherproof. Well it's not. It's been outside for 2 days and it rained last night and now it doesn't work at all. So now I'm stuck to walking. Thanks for nothing
