Use with a 50W rated flexible panel to maintain RV battery. Note this is above its rating (45W I believe) but actually output from the panel is below 45W.

Sturdy. Does the job for maintaining a car battery. Medium price. Saves on electricity(solar). You may need to buy an extender cord. I would recommend and buy again.

Great battery charger!

Verified Purchase

Used it already to charge a large deep cell battery during a power outage for 3 days. Running it in full sun during the day helps kept it up after basic nightly usage of the battery (laptop, lamp, charging phones for 4 or 5 hours...). I would recommend it very highly...sunpower baby! One minus...needs a padded or hard case for storage and transport.

Style: 5 Watt Solar PanelVerified Purchase

AC電源の無い場所でのバイクのバッテリー維持に使用しています。西向きに垂直にぶら下げて設置しています(西日は割と当たる所)。
充電状態がLED色で確認できるのが良いです(朝はオレンジで午後維持充電となるとグリーン)。
購入してもうすぐ2年ですが、エンジンはいつでも一発始動です。
コードは以前使っていた他の機器の時に、地面近くで何か(多分猫)にかじられ切れたことがあるので、別途スパイラルチューブ等で保護しています。
(2020/11追記)
もうすぐ5年となりますが順調に作動中です。パネルの一部が変色したりフレームの黒塗装があせて
金属色になりましたが、機能的には問題ないです。野ざらしなので耐久性は優良ではないでしょうか。
1〜2ヶ月に1回乗るかどうかですが、先日交換したバッテリーは8年持ちました(まだ使える状態)。
新品のバッテリーは満充電でランプがグリーンになりますが、少し弱ってくるとオレンジ以上には
ならなくなるようです。
ちなみにバッテリーに接続しない状態で受光しているとオレンジ点滅となります。
(2022/01追記)
昨年1月充電しなくなり10Wモデルに買い替えました。
パネル自体からは電圧は出ているので、コントローラーが壊れたようです。
新しい10Wの方はLEDを見るといつもグリーンなのでやはり余裕は有るみたいです。

Works Great! UPDATE REVIEW POSTED 11/20/14

Reviewed in the United States on February 26, 2012

Style: 5 Watt Solar PanelVerified Purchase

I purchased a Deltran Battery Tender JR 5 years ago as well as a motorcycle battery. Both the battery tender and the battery are still going strong 5 years later, this is not a typo! Yes, I said 5 years! Anyone who owns a motorcycle (especially a Harley) knows that you typically replace batteries every 2 years. Because of the performance of my battery tender Jr I decided to pick up this Deltran Solar Panel. I recently had to move my bike to a garage with no electricity and had to install the solar panel on the outside of the garage fully exposed to the elements. I've only had it about 2 months but I must say that this solar panel has performed above expectations. We have had some of the craziest weather on record in New Jersey. Warm days, cold days, heavy rains, 50 mph winds, 3 and 4 days at a time without sunlight. Yeah, Mother Nature has been sending us all kinds of craziness. So today I decided to go to my garage and see what kind of mess this solar panel was in. At the very least I expected to find the panel damaged by all the rain we've had. To my amazement it was working perfectly! It was 2 in the afternoon and cloudy due to all the rain and the solar panel LED was green indicating a fully charged battery. The panel has not been hit with any sunlight for 2 days yet it has been able to fully maintain my 5 year old battery. Another great product by Deltran.

UPDATE 3/28/2013: Here we are over a year after purchasing this Solar Panel and it continues to work great. It has been through some of the worst storms on record here in the East Coast without sustaining damage. My "very old" motorcycle battery continues to be maintained. The bike started easily even after 6 months of sitting in storage.

UPDATE 11/20/14: Well, my solar charger has failed. It no longer produces enough power under direct sunlight to keep a battery charged. Contacted Deltran for repair or replacement and they were more than willing to take a look at the charger for diagnosis but it would cost me more than half the cost of a new charger in shipping so I opted to take the loss and trash it. In defense of my particular charger, it has been through some brutal weather conditions since I purchased it and I'm not really surprised it failed. I would purchase another in a heart beat.

UPDATE 11/2/2015: I was going to add this update to my review last year but forgot all about it until I received a question on this item. I was able to find and fix the problem with my solar panel. Behind the panel is an access cover to the positive and negative wires. The black (ground wire) was lose. All I did was clean it off, tighten it and add a little dielectric grease. I checked the output with my multimeter on a sunny day and all worked great.
