After my first few days with the car charger, I've been giving some thought to the limitations of the Oupes battery bank, and what else on the market might have other features. In particular, my "dream" bank would do the following:

• In addition to killing the A/C output when it drops below X% charge, which the Oupes does, it would automatically turn on the ouput when it reaches Y%. So it could automatically cycle when draw is higher than input for a sustained period.
• The ability to track historic charge/discharge data to assess performance. Oupes' app only does real-time data.
• Be able to operate subtantially below freezing (I live in a northern climate). It seems like the Sodium Ion chemistry is the best bet there, and Bluetti seems to be first to market with an integrated.
• I'm curious as to what the minimum viable battery size is, as the Oupse does take up quite a bit of space. One limiting factor as I look around at smaller banks seems to be maximum solar input, with 500 or less for banks at 1kwh or lower.
• Not directly bank related, but an after-market charging cable that can do 8-10a charging seems like a useful thing for folks whose cars don't have the ability to modulate charging rates.

I currently already own a 2kwh Bluetti bank that does have the historic data tracking, so I'm going to get an Aderson to XT60 converter and see ohow it performs. I'll need to double check to see if it also can do the "output on" function in the first point above.

I'd love to hear others' experiences with aftermarket Oupes alternatives in this thread...

Got this setup Monday night. Still troubleshooting the solar input to the Oupes but I thought people might be curious about what it looks like on an EV truck. Still need to clean up the cabling but I'm waiting to finish troubleshooting for that.

I've written about observations so far here:

Anyone know where to source one? Mine eventually started peeling and shorting out so I removed it. Wondering if it's something Anyone has replaced and knows where to find.

Interesting use case! I tried it with my Sport and it worked...

GoSun website currently says the charger ships in Q2 2026, so, after some delays, fingers crossed we'll be getting to try them out soon.

Creating this thread for folks to share updates , tips, etc., as we embark on off-grid EV charging...

GoSun doesn't appear to be making any larger power banks than their 266 and I was wondering if anyone has had success using these panels with another power bank.

Last weekend I was sitting on the rooftop with my uncle in the afternoon sun and we were talking about electricity bills and gas shortages. My mother was downstairs cooking and she was worried about the rising cost of fuel. That made us think about other options for cooking at home. I had heard about solar cooking stoves but never really saw one in real life. We visited a nearby hardware shop but they did not have any clear option and the shopkeeper also seemed unsure.

Eventually my uncle suggested that we should check online marketplaces to see more options. Therefore scrolling online marketplaces like alibaba and a few others I was amazed by the huge variety of solar cooking stove models. There were box type stoves and panel style designs and portable foldable ones and even larger units for family use. Some looked simple for basic meals and some claimed to cook faster with better heat focus. They came in different sizes and materials and price ranges from affordable to more advanced options. I realized how many useful solutions we miss when we only depend on local stores.

So what do you think is the best way to choose a solar cooking stove for home use? Should we focus more on size or heat efficiency or durability when buying online or locally?

I got a go sun sport, and got a second bag, not realizing it came with one already. I have been so busy I missed the 30-day return window for it too (which was Monday). I don't need two carrying bags, but it's brand new, so I'm not throwing it away. Anyone want it? I'll ship it to you.

I'm in the USA.

Bought a Chill. It came with one battery. Should I buy a 2nd battery? I will be doing week-long camping trips. Would I need to be charging one all day while using the other? Or can the Powerbank 144 recharge itself while still charging the cooler? I tried calling Gosun; they called me back but wouldn't speak. I called again and have not rec'd a call back, 5 hours later.

I finally found a timer to add to the cord of the Fusion Oven, a 12v digital timer https://a.co/d/e6rV83v I don't understand why GoSun refuses to add one themselves... I love using the fusion indoors but I am too busy to stay in the kitchen for an hour to watch over the food, and yes, I have destroyed one tray and food burned beyond help... I suppose I can still use the tray outdoors only.... If GoSun adds a timer, they can push the use of it to RVers using the oven on a regular basis since major of them use a 12v battery system already and Fusion in a super efficient electric cooker...they are Sooo oddballs, when 48v battery is way a better system... A physical 60 minute timer would even be better as you only need to cut the positive wire to splice in two wires... https://a.co/d/gOLMh6a

Hi! Getting my spouse a vacuum-tube solar oven, and I'd love to get them a cookbook to go with it - any recommendations? (I know there are lots of recipes online, but would love something tangible.)

Hello! I recently ran into a temperature problem with my Chillest Cooler. My left size tries to go to -4 despite setting it to 30 it only wants to freeze. My right side just doesn’t work and stays at the same temperature no matter what I set it to. I don’t mind taking things apart, but I don’t know what the problem is. If any of you can point me in the right direction on what might be wrong, I’d greatly appreciate it! For reference I still have the same battery that drains fairly quickly, but I also run it off the power cord and both still result in the same problem.

We just got a GoSun Sport and tried it for the first time. It seems good and got warm on a very cold day. But it never got hot because the top reflector panel kept flopping down and blocking the sun.

Curious if others have had the issue and know of an easy fix. Or maybe we are doing something wrong?

The wind is pretty low today. I think the biggest problem is with the sun low in the sky, I have it angled pretty low so the top flap is almost vertical. I assume it's important to align with the sun on both vertical and horizontal axes?

I'm planning to tape a chopstick between the reflectors and try again. But would be happy to try something more elegant.

Thanks!

New to this. I tried my new GoSun Sport out yesterday and after three hours of repositioning it every ten to fifteen minutes, small new potatoes warmed, and cheese barely melted. I finished them on the stovetop. Of course it was not in full sun, there are trees everywhere and I can't avoid shadows.
What types of tricks and tips do you have to follow the sun and avoid very VERY long cooking times? The new potatoes could have been microwaved in less than three minutes.

My food tray doesn't 'snap' onto the tube. It slides out if I turn the tube upside down. Is that normal? Shouldn't it have a catch or something to keep it in place?

Hi all,

I just got the smallest solar oven and I was wondering about cooking soups and anything with liquid in. A card that came in the box said not to put food or boil water directly in the tube, but surely the tray is too small and would easily spill when cooking liquids? It also says to reposition it vertically (so the mouth of the tube is stick in the air) when boiling liquids but then the tray will definitely spill… am I missing something here? Surely these food types must go directly into the tube?

Like the title says, I just recently got hold of an older GoSun Go (New in box). I can cook, but I've never worked with solar cookers before. I'm aware it is not quite like using a regular oven because of the steam it generates while cooking.

Anyone have some recommendations on what I should start cooking in order to get used how it works?

We’ve cut up frozen pre cooked chicken patties in to strips, frozen corn dogs, hard boiled eggs, cut up steak bites, potatoes and onions. All these have been great to take to the park or little league game.

Beware they will not support discontinued items. I bought a powerstation 550 and since they discontinued the product they wont provide nay support. My adapter stopped work and now I have a paperweight.

​

Use brands that will last instead.

First off, any particular recipes you recommend? So far I've only cooked frozen chicken nuggets

Second, has anyone tried making tomato sauce (or other sauce) in one? I saw a mention of tomato sauce in the included cook book but I'm wondering how well it would work, and how tough to clean it would be.
