   他サイトで注文した20Wソーラーパネル、届いて開封すると、パネルサイズが非常に小さい。
   端子間開放時と短絡時の電圧・電流を調べると、発電量は10Wにも満たない品物でした。

   これは返品し、急遽、この商品をアマゾンに発注したら、中1日で届きました。
   試験日は午前中は晴れていましたが、お昼を回った頃から薄雲が広がっていました。
   それでもパネルの発電と、チャージコントローラーを介しての充電は確認できました。

   今後、パネルはフロントガラスの内側に置き、バッテリークリップは汎用２極端子に替え、ヒューズボックス内の常時バッテリーに接続されているところに接続する予定です。
   こうすれば、全てが車内に置かれるため、雨天時でも問題ありません。
   私が所有する他の2台もすべてこのようにして、補充電をしています。

   The monocrystalline solar panel that is included in this kit is very effective at transforming the sun’s rays into useful energy, and it does so with a high degree of accuracy. The power output of 20 W has proven to be more than enough to satisfy my charging requirements while I’m on the road. This solar panel set has proven to be a dependable source of renewable energy for me, whether I’m camping, traveling in a recreational vehicle (RV), going boating, or even using a gate opener. The charging efficiency of the kit as well as its overall performance have both greatly improved as a result of the integration of the MPPT charge controller. This clever controller optimizes the power output, making sure that my electronic gadgets get the most potential charge from the power source. Peace of mind is provided by the controller’s built-in protective systems, which safeguard against overcharging, reverse polarity, and short-circuiting. These safeguards protect not only the solar panel but also the electronic equipment I use. The adaptability of this solar panel kit and its user-friendliness makes it stand out from the competition. The adjustable mount bracket enables smooth integration into a variety of surfaces, such as automobiles, recreational vehicles (RVs), boats, motorbikes, and other vehicles. Even if the vehicle experiences jolts or is exposed to severe weather, the solar panel will not be dislodged from its mounting bracket since the bracket is robust and dependable.

   Left my truck hooked up to this while I was overseas for 6 months and was a little worried about it. Turns out it worked like a charm. Got back and my truck fired up as though it had a new battery. Perfect solar battery tender for the price

   Used to maintain my trailer battery during the winter. Worked great, easy to set up.

   Since I never give (or read) 5 star reviews this would get a solid 4 plus. Used it on both my backhoe and lawn tractor and fully charged both within a few hours. Would highly recommend it. The only negative is that one of the holes to support the stand hadn’t been drilled so I had to do so myself – a very minor issue and not worth returning or replacing the item over.

    I’ve been using this for about 6 months. It charges a regular lawnmower battery that I had laying around, runs a radio 24/7, and my 12V shop lights whenever I need them. Comes with everything you need to easily clamp directly to a battery. Lights indicate when charging and fully charged. It keeps my battery fully charged with the radio always on.

    Light weight, nice quality, comes with all the essentials necessary to make the install quickly. I installed this trickle charger on a standby generator in order to maintain the battery for start ups. I now have had this installed for approximately a year and appears to be working great.

    I bought this to install on the outside of my generator shed to keep the battery maintained. I think it may say that it’s a solar battery charger but I believe it’s more of a maintainer, but that’s all I need it for. Easily installed and so far it’s working great!
