Running a goal zero boulder 100 briefcase yeti 700 rooftop tent moab setup is the cleanest way to keep your rooftop tent base camp powered through three to five nights of Utah desert dispersed camping. The Boulder 100 Briefcase delivers roughly 100W of rigid monocrystalline solar through an 8mm output that plugs directly into the Yeti 700's solar input, recovering about 18-22Ah per peak sun day at Moab's elevation. Position the briefcase on flat slickrock 10-15 feet from your vehicle, angle it 35-40 degrees south, and you'll cover a 12V fridge, LED tent lights, phone charging, and a CPAP without ever idling the truck.
Below, we'll cover exact panel placement for Moab's BLM dispersed sites, cable management when your Yeti 700 lives in the truck bed under a rooftop tent, and three backup power banks worth tossing in the tent for redundancy when afternoon thunderheads roll in over Arches.
Why the Boulder 100 Briefcase Pairs Best with the Yeti 700 in Moab
The Yeti 700 (formerly Yeti 500X / now sold as Yeti 700 in the 2026 lineup) has a 187Wh-class lithium battery in the older spec and a refreshed ~700Wh LiFePO4 cell in the new revision. Either way, the Boulder 100 Briefcase is the sweet spot: it folds in half, latches like a suitcase, weighs around 25.5 lbs, and uses tempered glass over monocrystalline cells that shrug off red Moab dust. Compare that to a flexible 100W panel that warps in 105°F slickrock heat, and the rigid briefcase is the obvious pick for stationary base camp use at sites like Sand Flats Recreation Area or the Gemini Bridges dispersed corridor.
The reason this combo works specifically for rooftop tent campers is the geometry. Your Yeti 700 typically lives in the truck bed, drawer system, or rear cargo area — directly below the tent. The Boulder 100's integrated kickstand lets you deploy it on the ground next to the vehicle, run a single 8mm extension cable up to the truck, and leave the tent ladder unobstructed. No roof mounting, no drilling, no permanent install.

Moab-Specific Deployment: Angles, Sun Hours, and Dust
Moab sits at 4,025 ft elevation and gets roughly 6.5-7.5 peak sun hours from April through October. For a goal zero boulder 100 briefcase yeti 700 rooftop tent moab configuration, you want:
- Tilt angle: 30-35° in summer, 45-50° in shoulder seasons (March, October).
- Azimuth: True south. Compass south in Moab is about 12° east of magnetic.
- Shading: Watch for juniper and pinyon shadows after 3pm. Even partial shade on one cell drops output 60%+.
- Dust: Wipe glass each morning with a microfiber. Red dust accumulates fast and costs 8-15% output.
Realistic daily harvest at a Moab BLM site in May: 70-85Wh out of a theoretical 700Wh. That's enough to top off the Yeti 700 from 60% to full, run a 45-quart 12V fridge (about 30Wh/day in cool weather, 60Wh in heat), and still have margin for device charging.
Cable Routing Under a Rooftop Tent
The annoying part of any rooftop tent + power station build is cable management when the tent is deployed. The Yeti 700's solar input is on the side panel, so route the 8mm extension along the inside of your bed rail, up through a Molle panel or T-slot in your bed rack, and let it dangle out to the panel on the ground. Don't run it over the tent fabric — UV and abrasion will kill the jacket in one season. A 15-30 foot 8mm extension is typically enough; longer than that and you'll want to upgrade to MC4 with a Goal Zero adapter to minimize voltage drop.

Backup Power Banks for the Tent Itself
The Yeti 700 should live below in the truck. Inside the tent, you want lightweight USB power banks for phones, headlamps, Kindle, and Starlink Mini if you're working remotely. Here are the picks I actually recommend for 2026 Moab trips.
SOARAISE Solar Charger Power Bank 48000mAh Wireless
The SOARAISE 48000mAh is the tent-side workhorse. It has a built-in trickle solar panel (don't rely on it as a primary charge source — it's an emergency feature), Qi wireless charging on the top face, and three USB outputs including USB-C PD. At Moab, I clip it to the tent's interior pocket and use it to charge two phones and a headlamp overnight. The flashlight mode is genuinely useful when you're climbing down the ladder at 2am. Check current price on Amazon.
YELOMIN 38800mAh Solar Power Bank, USB-C Fast Charging
If you're charging a laptop or Starlink Mini from the tent, the YELOMIN's USB-C PD output (up to 22.5W in my testing) is the differentiator. It's slimmer than the SOARAISE, fits in a Yeti tent's gear loft pocket, and tops off a MacBook Air maybe 40% from full. Pair it with the Yeti 700 during the day, then take it up into the tent at night. Check current price on Amazon.
Portable Solar Generator 300W with Foldable 60W Panel
This is the backup-to-the-backup. If your Yeti 700 fails, gets stolen out of an unlocked truck, or you simply want a second power station to run a CPAP independently of the fridge, the 300W generator with included 60W folding panel is the budget play. It won't replace the Yeti 700 — the LiFePO4 cycle life isn't there — but as a redundant unit at $200ish, it's defensible. Check current price on Amazon.

Amazon Basics High-Capacity Portable Charger Power Bank
Sometimes you just want a simple, no-solar, no-wireless, no-frills 20,000mAh brick that costs $25 and lives in your tent ditty bag forever. The Amazon Basics unit charges phones via USB-C PD, recharges itself in about 4 hours, and doesn't have a fragile little solar panel that breaks the first time you drop it on slickrock. I keep one in every vehicle. Check current price on Amazon.

What I'd Actually Bring on a 4-Night Moab Trip
For a long weekend at Hurrah Pass or Top of the World dispersed sites, my goal zero boulder 100 briefcase yeti 700 rooftop tent moab kit looks like this: the Boulder 100 Briefcase as the primary solar input, a 30-foot 8mm extension cable, the Yeti 700 in a drawer under the rooftop tent ladder, the SOARAISE 48000mAh clipped inside the tent for phones and the Kindle, and the Amazon Basics 20,000mAh in my day pack for mountain biking the Whole Enchilada. The 300W backup generator stays home unless I'm leading a group and need to power someone else's CPAP too.

Frequently Asked Questions
Can the Goal Zero Boulder 100 Briefcase fully recharge a Yeti 700 in one Moab day?
From a fully depleted state, no — not in a single day. The Yeti 700 (700Wh revision) takes roughly 10-14 hours of peak sun with a 100W panel to go 0-100%, and Moab gives you 6.5-7.5 peak sun hours in summer. From 40% to 100%, yes, easily. The realistic workflow is to never let the Yeti drop below 30%, then daily solar tops it back to full by mid-afternoon.
Do I need to angle the Boulder 100 Briefcase or can I lay it flat on the ground?
Always angle it. Laying flat in Moab loses about 25-35% of harvest in summer and even more in shoulder seasons. The integrated kickstand makes 35-45° trivial. Reposition it once at midday if you want to squeeze out the last 5-8%.
What if I'm at a shaded site like Kane Creek?
Shade kills any solar setup. At cottonwood-shaded sites near Kane Creek or along the Colorado River, plan to drive 5-10 minutes to a slickrock open area, deploy the Boulder 100 there for 4-6 hours to charge the Yeti 700, then return to camp. Alternatively, bring a backup like the 300W solar generator as redundancy and charge it on the highway via 12V on your drive in.
Can I leave the Boulder 100 deployed overnight in Moab?
You can, but I don't. Moab gets sudden microbursts in monsoon season (July-September) that have flipped my panel twice. Weight it with a rock through the carry handle, or break it down and slide it under the truck at night. The Yeti 700 itself can stay in the bed.
Will the Boulder 100 charge the Yeti 700 through the windshield?
Modern automotive glass blocks 30-50% of the spectrum the panel uses. You'll get something — maybe 25-40W on a clear day — but it's not a substitute for ground deployment. Useful only as a passive top-off while you're driving between trailheads.
What size cable extension do I need between the Boulder 100 and the Yeti 700?
Goal Zero's 30-foot 8mm extension is the standard pick and what most rooftop tent users run. If you need longer than 30 feet, switch to a 10 AWG MC4 cable with an 8mm adapter on the Yeti end to minimize voltage drop. Voltage drop matters more than people realize — a thin 50-foot extension can cost you 10-15% of your harvest.
Is the Yeti 700 enough for a CPAP, fridge, and phone charging at Moab?
For 2-3 nights, yes, with daily solar input from the Boulder 100. A typical CPAP without humidifier draws 30-40Wh per night, a 45-quart fridge in 90°F ambient draws 50-70Wh per day, and phones are negligible. That's ~100-130Wh/day total — well within the Boulder 100's harvest envelope at Moab. Run the CPAP humidifier and you'll double the CPAP draw, in which case bring a backup like the SOARAISE 48000mAh for device-level charging to spare the Yeti.
