Haines 2.0 SunUp Solar Cooker and Dutch Oven Kit

Overview: who it's for

The Haines 2.0 is a panel-style solar cooker. A set of reflective foam panels, which its makers call petals, open into a wide funnel around a dark cooking pot that sits in a clear insulating sleeve. Sunlight bounces off the panels onto the pot, the black pot turns it into heat, and the sleeve holds that heat in. There's no fuel, no flame and no electricity.

It's made by Haines Solar Cookers. Roger Haines, its designer, sits on the board of Solar Household Energy (SHE), a nonprofit that uses the cooker in its projects. That background matters because it's one of the few consumer solar cookers with independent, published performance testing.

What the Amazon link sells: the "Haines 2.0 SunUp Solar Cooker and Dutch Oven Kit," model H20, part number 1509. That's the cooker plus a cooking pot. Haines also sells the cooker without the pot under a separate Amazon listing. We link to the kit because a panel cooker needs a dark, lidded pot to work. Haines's own product page sells the cooker with a 4.5-quart stainless steel Dutch oven with a black exterior and a tempered glass lid. The Amazon kit listing doesn't describe the pot in detail, so check its size and material on the listing before you buy.

This review is research-based. VanLifeKitchens doesn't test products hands-on. Specs come from Haines's product page and from SHE's write-ups of a University of Malaga study and of the cooker's heat-retention use. Cooking-condition advice is general solar-cooking practice, and we say where it is.

Choose this if:

• You camp for days in strong, reliable sun and want to cook stews, rice, beans or roasts without fuel.
• You want a cooker that folds flat and weighs under 2 lb without its pot.
• You like meals you can start and leave, and you're happy cooking on the sun's schedule.

Skip this if:

• You want fast cooking. The GoSun Sport cooks in minutes what this cooks in hours.
• You travel where the sky is often hazy, cloudy or the sun is low for much of the year.
• You need dinner at a fixed time. Solar cooking needs a stove as backup.

How it works

A panel cooker doesn't trap heat the way a box oven does. It concentrates sunlight onto a pot and relies on the pot and its cover to hold the heat.

• Reflector. Haines describes it as "reflective Mylar bonded to polyethylene foam making it strong but flexible." Haines says the reflector "will not scratch or oxidize and is not affected by spilled boiling water."
• Cooking sleeve. A clear sleeve goes around the pot. Haines says it "insulates and elevates the pot," lifting it off the ground and cutting heat loss to the air.
• Pot. A dark pot absorbs the light. Haines's page describes its 4.5-quart Dutch oven as stainless steel with a black exterior and a tempered glass lid, so you can see the food without lifting the lid. Haines notes that "only the cooking pot gets hot." Use oven gloves to handle it.
• Sun angle. Haines says the cooker is "adjustable for low and high sun angles to maximize solar energy, which allows you to cook early and late in the day." SHE notes that red snaps on the cooker are for use when the sun is above 75°, which SHE describes as when your shadow is less than a third of your height.

Heat retention. SHE describes a second use: when cooking is done, the four petals fold up around the pot to form a square basket. SHE says food "will continue cooking for many hours" this way, and that solar-cooked food can be "kept piping hot for 4 to 6 hours for the evening meal." You can add towels around the pot for more insulation. That turns a midday cook into a hot dinner.

Specifications and measured performance

What "87 watts" means. Solar cooker power is measured as the rate the cooker heats a known load of water under standardised sun. The University of Malaga study, published in the journal Energy in 2022 and summarised by SHE, gives 87.7 W at a 3.5 kg load and a 70° solar altitude. Solar Cookers International's PEP test gave 82 W. These are standardised figures for comparing cookers, not what you'll get every day. Your result falls with haze, wind, a low sun or a cold day.

For comparison, a small 1,000 W electric hotplate is rated at more than ten times that power. That's why solar cooking is slow, and why the insulating sleeve and the heat-retention basket matter so much.

What Haines doesn't publish on the page we checked. A folded size, a maximum temperature and a warranty term. The Amazon listing's dimensions (35 x 35 x 20 inches) look like the set-up size or packaging, not the folded size. Haines's page notes a 30-day return policy for its own store, which doesn't apply to an Amazon purchase, so check the listing's return terms.

Conditions: sun, wind and time

This is what decides whether a panel cooker works for you.

Sun. You need direct sun with no shade on the cooker or pot. Thin haze cuts output noticeably and thick cloud stops cooking. Higher sun means more energy, which is why SHE's study figure is given at a 70° solar altitude. Midday in summer at mid-latitudes is the best window. In winter, or early and late in the day, the sun is low and output drops, though Haines's adjustable panels help.

Wind. Haines doesn't publish wind guidance on its product page. General solar-cooking practice is that wind is the second biggest enemy after cloud. It carries heat off the pot and the sleeve, and a lightweight foam reflector can blow over. Set the cooker in the lee of the van or a windbreak, and weigh or stake it down if it's breezy.

Time. Haines says it can boil a quart of water in as little as 40 minutes, depending on conditions. Full meals take longer, often a few hours in good sun by general solar-cooking experience. Plan to start a stew, beans or rice by late morning for a mid-afternoon meal, then fold the petals up to keep it hot until evening. Re-aim the cooker toward the sun every hour or so as it moves.

Food safety. A slow cooker of any kind can leave food in the warm range where bacteria grow if the pot never gets hot enough. Use a thermometer, start early in strong sun, and if the weather turns before food is cooked through, finish it on a stove. Don't leave cooked food sitting in a cooling pot for hours.

How it fits van life

Storage. The reflector folds flat and weighs 29 oz without the pot, per Haines. That's light enough to slide behind a seat or under a mattress. The pot is the bulky part. A 4.5-quart Dutch oven takes as much cabinet room as any large pot, though it can double as your normal stew pot on a stove.

Where you use it. Outdoors, in full sun, on flat ground or a table. It needs open sky, not a spot behind the van's windscreen.

As a fuel saver. Every fuel-burning stove on this site is labelled by its maker for outdoor use. A solar cooker doesn't change that. What it does is take long, slow cooks off your gas or battery on sunny days. A pot of beans that would mean an hour of burner time costs nothing. On cloudy days, your stove does the job. Our solar cooking complete guide covers when solar cooking makes sense and when it doesn't.

Glare. The reflector throws bright light. Don't stand looking into it at midday, and point it so the glare doesn't hit neighbouring campers.

How it compares with the other solar cookers on this site

The GoSun Sport is much faster and handles wind better because its vacuum tube loses little heat. It cooks less food at once. The Sunflair is a box oven that folds flat. Our Haines 2.0 vs GoSun Sport comparison and Sunflair vs GoSun Sport comparison go deeper.

Limitations

• Slow. About 87 W of cooking power, measured under standardised sun.
• Weather-dependent. Needs direct sun; struggles in haze, wind and low winter sun.
• Needs attention. Re-aim it as the sun moves.
• Pot details unclear on Amazon. Confirm what the kit listing includes.
• No published folded size or warranty on the Haines page we checked.

Verdict

The Haines 2.0 SunUp kit is a light, fold-flat panel cooker with unusually solid evidence behind it: about 87 W of cooking power in a peer-reviewed study and 82 W in Solar Cookers International's test. Haines says it can boil a quart in as little as 40 minutes, and SHE describes folding the petals into a basket to keep food hot for hours. It's a slow cooker for clear, calm days, not a stove replacement, and the pot is the bulky part to store. If you spend long stretches in sunny places and like one-pot meals, it can take a lot of slow cooking off your fuel or battery. If you want speed, the GoSun Sport is the better tool.

FAQ

How hot does the Haines 2.0 solar cooker get? Haines doesn't publish a maximum temperature on its product page. It publishes cooking power instead: 87 W in a peer-reviewed study and 82 W in Solar Cookers International's PEP test. Haines says it can boil a quart of water in as little as 40 minutes, depending on conditions.

How long does it take to cook a meal in the Haines 2.0? Haines publishes a boil time, not meal times. In good sun, plan for meals measured in hours, and start by late morning. Haze, wind and low sun all slow it down.

Does the Haines 2.0 work in wind? Wind cools the pot and can blow over a light reflector. Haines doesn't publish wind guidance on its product page. Use it in the lee of the van or a windbreak and weigh it down.

Does the Amazon kit include a pot? The listing is titled "Haines 2.0 SunUp Solar Cooker and Dutch Oven Kit." Haines's own page sells the cooker with a 4.5-quart black stainless Dutch oven and glass lid. Check the Amazon listing for the pot it includes.

Can I keep food warm in the Haines 2.0? SHE says the four petals fold up around the pot to form an insulated basket, and that solar-cooked food can be kept hot for 4 to 6 hours. Adding towels around the pot helps.

Haines 2.0 or GoSun Sport? The GoSun is much faster and copes better with wind, but holds less food. The Haines is lighter, folds flat and suits slow pot meals. Our comparison covers the details.
