Overlanding purists may sneer at the idea of bringing boatloads of tech into the backcountry. But, if you’re someone who likes hardcore off-road exploration and a healthy dose of tech-heavy creature comforts, there’s never been a better time to be alive. With that in mind, EcoFlow just debuted the latest iteration of its Wave portable air conditioner, and it’s every bit as cool as it sounds.

The brand, best known for its best-in-class portable power stations, took more than two years of user feedback into account before releasing the Wave 3. This next-gen version is smaller, lighter, and more powerful than its predecessors with enough oomph to cool or heat spaces ranging between 118 to 183 square feet. Think: Teardrop travel trailers, compact RVs, or even ground tents. EcoFlow claims the unit can lower temps by up to 15 degrees Fahrenheit in just 15 minutes with 1,800 watts of cooling power, or raise the temperature by 17 degrees Fahrenheit with up to 2,000 watts of heating power. Translation: Year-round off-grid climate control.

For overlanders and car campers, the Wave 3’s real strength lies in its portability and versatility. It requires zero installation. At roughly 20″ x 12″ x 13″ and weighing just under 34 pounds, it’s roughly the size of an average 1,500W power station. The 1,024Wh LFP battery is good for up to 4,000 cycles and delivers up to eight hours of cooling in its most efficient Eco Mode. Plus, it’s easily rechargeable in as little as 75 minutes and can be powered or topped up via the inlcuded AC power connection, a solar setup, a standard 12V car outlet, or EcoFlow’s own Alternator Charger. Because it runs on R290 refrigerant, it’s far more efficient and eco-friendly than traditional R32.

The Wave 3 portable air conditioner/heater is available for pre-order directly through EcoFlow with an MSRP of $1,299 with a single battery. You can also score extra batteries for $899 per. The product officially launches Friday, April 25, and EcoFlow promises deep discounts to the earliest bird buyers.

Runaway Campers’ Venturist is a rugged “squaredrop” towable for minimalists

With more than 20 inches of ground clearance, this hardcore teardrop trailer has serious off-roading potential

I'm of the school of thought that "simpler is almost always better," especially when it comes to camping. Whether it's backpacking, RV camping, or overlanding, less is often more. It's clear that Runaway Campers agrees. Case in point: It's perfectly minimalist Venturist "squaredrop" travel trailer series.

Each of the three models in the Venturist series (or "V-Series") comes standard with everything avid overlanders need and nothing they don't. That means a steel frame construction, Timbren axle-less independent suspension, electric brakes, custom fenders, and 17-inch wheels on 33-inch BFG all-terrain tires. The setup provides more than 20 inches of ground clearance. Coupled with a pint-sized footprint, this travel trailer is purpose-built to be easy to tow and maneuver along even the tightest and gnarliest of backcountry trails.

Aterra Slide-In truck camper transforms your pickup into an overland-ready rig

Get the DIY shell with only the essentials or upgrade to a full-blown, ready-to-overland ride

For our money, there's no better solution for overlanding than a classic truck camper. Now, Arizona's AT Overland Equipment has just debuted an all-new slide-in solution that perfectly balances weight, features, and price.

The Aterra Slide-In is the latest addition to AT Overland Equipment's Aterra series. It's designed for maximum versatility and customizability for full-sized pickup owners who want a truck camper that's exactly as dialed-in as they need it to be. The base model is merely a lightweight (roughly 750 pounds) shell — a blank canvas, if you will — designed to be the perfect starter for your DIY build. The surprisingly spacious interior offers a 6'9" standing height and a few essentials, like an RV King-sized sleeping area with a mattress, dual-pane Tern Windows, and a locking Tern rear entry door. It's all well-insulated with an R6 value and R7 for the roof.

Rumpl Wrap Sack is the Goldilocks “un”-sleeping bag you never knew you needed

It offers the warmth and comfort of a traditional 20° sleeping bag with the versatility of a camp quilt

Young camper tucking into a Rumpl Wrap Sack sleeping bag inside a rooftop tent.

It wasn't until fairly recently that I discovered the joys of swapping my traditional sleeping bag for a camp quilt, but I've never looked back. Especially for car camping and overlanding, the latter is infinitely more versatile and comfortable for the way I sleep. But Rumpl's Wrap Sack is a clever, new "un"-sleeping bag that has my attention.

The Wrap Sack is shaped like an ordinary sleeping bag, but that's really where the similarities end. Rumpl designed it to be far more versatile thanks to its clever WrapAdapt system. Campers can opt to wrap and zip themselves inside the two built-in layers for cold-weather outings or unzip and completely "de-layer" when the temperature heats up. With a 20-degree rating, the Wrap Sack works well as a three-season bag, so it's good for all but the coldest camping trips. The design accommodates campers up to 6'2" and is wider and roomier than old-school mummy sleeping bags, making it great for anyone (me!) who hates feeling like a tightly swaddled newborn while sleeping. Plus, thanks to an integrated pillow pocket, it's purpose-built to pair with Rumpl's own Camp Pillow.
