ENGINSTAR 60W Foldable Solar Panel Charger with 18V DC Outlet for Portable Power Stations EnginStar/Jackery/Rockpals/Flashfish, Portable Solar Generator with QC 3.0 for Outdoor Camping Van RV Trip

Great product for the price and a very durable build. Fairly heavy and also reliable in full sun. I'm happy with my purchase and recommend it for anyone looking for a high quality solar panel for a low power device

This was so awesome it came in handy and it charged up my external battery really quickly. I just used it when I ran out of electricity during a power outage for about 8 hours in July and the Florida heat so I just ran a portable Air conditioner and a few phone chargers off it and it was perfect. I'll also write a radio about the external battery because that's actually where you plug into.

It seems to be of good quality when the sun is in full strength. The charging is very good. I cannot complain! It is not super sensitive, so when the sunlight is low/cloudy, it hardly charges. But that is to be expected for an inexpensive solar charger!

Bueno

I used this along with a large portable power bank for when my unit would go to the field. I tested it at home first. The power bank i have shows how much of a charge it is getting and, with direct sunlight, this thing will charge just as fast as the wall outlet. It is easy to set-up and carry around as well. I highly recommend this for campers or those military personnel stuck out in the field.

Works beautiful

Purchased this to recharge my battery pack for camping. I have to bring my CPAP machine while camping or the whole Northern Woods will be awake for the nights! This 100 watt panel does deliver as described. Worth noting that the best output is in full sun. That being said... even with passing clouds, this panel recharged my RockPals battery pack in a matter of a couple of hours, from 20% to 100% daily on our 5 day tent camping trip. This panel does fold to a rather flat briefcase style pack weighing around 5 pounds-ish, which packed nicely in the gear totes. This panel can be floppy when trying to arrange an array, though a little patience and utilizing the terrain, I was able to achieve nearly 70 watt output in full sun.

This was a *supposed* replacement for one that I recently purchased & then returned; bc of seemingly, lesser-quality charging. It also happened to come in a damaged box. It looks suspiciously like the original had been repackaged in a undamaged box & sent as new. The panels had a peculiar look to them that wasn't 'symmetrical' > like an off, multi-tinted, scattered, patchwork layout. Of course, I don't know if that indicates lesser quality/change in the manufacturing/design; or if it was a lemon product. I say 'lesser,' because I, previously, ordered this same item over a year ago & the panels *looked* different & to be of better quality. Meaning, *not* having a strangely, noticeable, patchy look to some of the panel 'components'(?) in the layout. The photo is the best that I could do camera/light wise. So, I guess returning it is a moot point if I'm just going to get it returned again as new... AND be tagged as a problem/repetitive returner/complainer. Thanks for nothing to all involved. Enjoy the free $$ while it lasts. 🤨

Enginstar ポータブル電源 R300 大容量 110000mAH/407Whの充電用に購入しました。 自然災害も増えてきているので万が一の時に使用できればと思い。 10年前くらいから粗悪なソーラーパネル製品がでて新しいもの好きなので購入して後悔ばかりしていました。 しかしながら製品の進歩は凄いもので、ポータブル電源への充電もしっかりでています。 届いた時には意外と小さいなと思ったのですが、箱を開けて広げたら大きかったです。 なので多少重さはあります。 真夏の駐車場に広げておくと充電量(？)60wくらい表示され、10時から15時くらいまで放置していたらポータブル電源のバッテリーが50%からほぼ100%まで充電出来てました。 大して調べないで買ったのですが、ポータブル電源への充電だけでなく、直接USBを繋げて電源供給出来る？っぽい感じがするのでまた今度試そうと思います。 あとは耐久性がどれくらい持つか、しばらく使ってまたレビュー更新しようと思います。

災害時の停電対策として購入。お手頃の値段と100W発電で考えると魅力的なものだと思います。 重さは想像以上。 でも折り畳み式で収納しやすいのでまぁ許す。使ってみたら充電が早いとは言えないが、ＵＳＢ（タイプＣ）に対応でタブレットと携帯充電が出来て、今の所は満足です。

晴れた日に正しく太陽に向ければ、下記ポータブルバッテリーで、実質60Wで充電できることを確認しました。 Anker PowerHouse II 800 (ポータブル電源 大容量 216,000mAh / 778Wh)【純正弦波 AC500W(瞬間最大1,000W) / 11台同時に充給電 / 合計最大出力770W / ◇PSE技術基準適合】 購入時は、約20000円でしたがキャンペーンで13600円で購入しましたが、2021/04/21現在は、13600円で販売されています。もともと13600円だったのかと思うと、価格設定という意味であまり信用できる会社ではなさそうです。

猛暑の中キャンプで突然充電出来なくなりました。 帰宅後ﾃｽﾀ-にて確認、アース側が通電してなく間に合わせにリード線を半田付け使用 AmazonにてDCプラグを購入しました。

キチンと角度を合わせれば、晴れた昼間は60ワット位で充電するようです。雨には濡らさないほうが良さそうです。
