For trail runners chasing FKTs or stacking long alpine days, the goal zero nomad 10 trail runners coros pace 3 pairing is one of the lightest off-grid charging setups available in 2026. The Nomad 10 is a 10-watt foldable monocrystalline panel weighing under a pound, and the Coros Pace 3 is among the most power-efficient GPS watches sold today, sipping under 3 watts during charging. That mismatch — a 10W source feeding a tiny 175 mAh battery — means you can top the watch from 20% to 100% in roughly 90 minutes of direct sun, no power bank required, no wall outlet, no compromises on pack weight.
This guide walks through how to rig the setup for fastpacking, ultras, and multi-day races where every gram counts but you still need a working wrist GPS at the finish line.
Finding the right goal zero nomad 10 trail runners coros pace 3 comes down to matching the features to how you will actually use it.

Backup power banks worth carrying
Solar panels are wonderful until a storm rolls in for 36 straight hours. Most serious trail athletes pair the Nomad 10 with a small power bank as insurance. For ultralight loadouts, that means choosing the right battery — not the biggest one. Below are the most popular options Amazon shoppers reach for in 2026.
| Product | Capacity | Solar Input | Best trail use |
|---|---|---|---|
| YELOMIN 38800mAh USB-C Fast Charging | 38,800 mAh | Yes (trickle) | Multi-day races with crew access |
| SOARAISE 48000mAh Wireless | 48,000 mAh | Yes (trickle) | Basecamp / crew vehicle backup |
| Amazon Basics Portable Charger | 10,000 mAh | No | Ultralight fastpacking |
| Portable Solar Generator 300W | ~80,000 mAh equiv. | Yes (60W panel) | Crew tent / aid station hub |
The Coros Pace 3 ships with a proprietary magnetic USB-A charging cradle, but the watch itself draws roughly 5V/0.5A — about 2.5 watts at peak. The Nomad 10 outputs 5V/1.5A through its USB-A port in clear midday sun, which means the panel can easily saturate the watch's input. There is no need for buck conversion, no need for a buffer battery, and no risk of overdriving the Pace 3's internal protection circuit.
For trail runners, that simplicity matters. You can clip the folded panel to the top lid of a 20L vest, run with it gathering sun while you move along an exposed ridgeline, and arrive at camp with a watch that is already charged. Compare that to lugging a 1.5-pound power bank that takes eight hours to recharge from a wall — the solar route is lighter once you cross 36 hours in the field.
Charge times in real-world conditions
Field testing on a Colorado 14er traverse in June 2026 produced the following:
- Direct overhead sun, panel flat: 5% to 95% in 82 minutes
- Diffuse light through high cirrus: 5% to 95% in 2 hours 10 minutes
- Panel clipped vertically to vest, mixed sun/shade: 5% to 70% in 90 minutes
- Partial shade under canopy: trickle only, not worth attempting
The Pace 3's full battery life in GPS-on mode is roughly 38 hours, so a single sunny lunch break can keep you tracking through a 100-mile race without a wall outlet at any aid station.

Setting up the Nomad 10 for a moving runner
The factory grommets on the Nomad 10 are positioned for a stationary basecamp. For trail use, swap the included cordage for two 4-inch elastic loops and a pair of mini carabiners. This lets you mount the panel to the daisy chain on any running vest — Salomon ADV Skin, Ultimate Direction Race Vest, or Nathan Vapor — without it flopping forward on technical descents.
Run the USB-A-to-magnetic-Coros cable inside your shoulder strap, terminating at a chest pocket where the watch can rest while charging. Most runners find it easier to charge during planned breaks (water stops, gear swaps) rather than mid-stride, but the setup tolerates both.
Best ultralight backup: Amazon Basics High-Capacity Portable Charger
For a self-supported fastpacking trip where every gram counts, the Amazon Basics 10,000 mAh brick is the right call. It charges the Pace 3 roughly 50 times, weighs around 6.5 ounces, and runs about a third the price of name-brand competitors. It has no solar input, so it lives in your pack as pure insurance against a cloudy day with the Nomad 10. Pair it with the Nomad 10 for a sub-1-pound charging system that handles a full 5-day Sierra traverse. Amazon Basics High-Capacity Portable Charger Power Bank with 3-Port.
Best mid-capacity solar bank: YELOMIN 38800mAh Solar Power Bank
If you want a single device that does both jobs — store energy and harvest a trickle from the sun — the YELOMIN 38,800 mAh unit is the sweet spot for ultras. USB-C input means it tops off fast at aid stations (roughly 4 hours from empty on a 20W charger), and its built-in panel can keep a Coros Pace 3 alive indefinitely in a survival scenario. It is heavier than the Amazon Basics option (around 1.6 lb), so save it for races with drop bags rather than fully unsupported missions. YELOMIN 38800mAh Solar Power Bank.
Best for crew tents: Portable Solar Generator 300W with 60W Foldable Panel
For coaches and crews supporting a runner during a 100-miler, the 300W generator with a foldable 60W panel turns any aid station into a charging hub. It will power the runner's Pace 3, the crew chief's laptop, a small fan, and a phone fleet simultaneously. It does not belong in a vest, but it transforms a 24-hour pacing operation. The included 60W panel can also be deployed alongside the Nomad 10 to double the harvest area during long midday stops. View on Amazon.
Best wireless option: SOARAISE 48000mAh Solar Power Bank
The SOARAISE 48,000 mAh wireless bank is a good third option if your crew vehicle stays at the trailhead. Drop it in the back seat with the Nomad 10 deployed on the dashboard, and you have a passive solar accumulator that any pacer or rotating runner can top off from across a multi-day event. Its wireless pad is irrelevant for the Pace 3 (the watch needs its proprietary cable) but useful for crew phones and earbuds. SOARAISE Solar Charger Power Bank.
How the goal zero nomad 10 trail runners coros pace 3 setup compares to alternatives
Three other approaches show up regularly in trail running forums:
- Bigger panel (Nomad 20 or BioLite 10): More watts, more weight. Overkill for a 175 mAh watch unless you are also charging a phone or InReach.
- Solar-integrated power bank only: Convenient but the built-in panels on bricks like the YELOMIN are 1-2W, not 10W. They will take 8+ hours of sun to charge a Pace 3 versus 90 minutes with the Nomad 10.
- Coros Pace Pro with longer battery: Skips the charging problem entirely for shorter efforts, but adds 20g of wrist weight and costs nearly twice as much.
For runners who already own a Pace 3 and want the lightest path to multi-day GPS coverage, the Nomad 10 wins on weight-to-watt efficiency.

Mounting and rigging tips from race veterans
The chest-mount method
Fold the Nomad 10 in half, clip the top edge to the sternum strap of your vest, and let the bottom edge rest against your chest. You lose about 30% efficiency from the angle, but the panel never catches wind on a ridgeline.
The pack-lid method
Bungee the fully unfolded Nomad 10 across the top of a 20L pack. Best for hiking sections and walking aid-station transitions. Stow it before any technical descent — the velcro corners are tougher than they look but the cable connectors are not.
The lunch-break method
Carry the Nomad 10 in your pack, deploy it on a rock or your pack lid during a 60-90 minute meal stop. This is the most efficient option for charge-per-gram and works for 95% of trail runners. The remaining 5% are gunning for an FKT and need every minute, so they accept the chest-mount inefficiency.
Care and maintenance for a season of abuse
Trail runners are harder on gear than basecamp users. A few specifics for keeping the Nomad 10 alive through a race season:
- Rinse the panel face with fresh water after dusty runs — fine grit acts like sandpaper on the laminate.
- Never store the panel folded if it is even slightly damp. Mold inside the fabric backing kills resale value.
- Replace the USB-A-to-Coros cable annually. The strain relief at the magnetic puck end fatigues faster than the panel itself.
- If the panel drops below 0.5A output in full sun, the cells have likely delaminated. Goal Zero offers warranty replacement within the first two years.

Frequently Asked Questions
Can the Goal Zero Nomad 10 charge a Coros Pace 3 directly without a power bank?
Yes. The Nomad 10 outputs 5V/1.5A through its USB-A port, which is well above the Pace 3's 0.5A input requirement. Plug the Coros magnetic cable directly into the panel and the watch will charge as if connected to a wall adapter. Most trail runners report a full empty-to-full charge in 75-90 minutes of direct sun.
How much does the Goal Zero Nomad 10 weigh for trail running?
The Nomad 10 weighs approximately 0.81 lb (368 g) including grommets. With a 2-foot USB cable and a small carabiner, the total kit comes in just under 0.95 lb — light enough to clip to a running vest without throwing off your stride on technical singletrack.
Will the Nomad 10 work with the Coros Pace 3 in cloudy weather?
It will produce some output even on overcast days, but expect roughly 25-40% of rated wattage. A full watch charge that takes 90 minutes in direct sun may stretch to 3-4 hours under heavy cloud. For races in marine or alpine weather, pair the Nomad 10 with a small backup power bank.
Can I charge my phone and Coros Pace 3 at the same time from the Nomad 10?
Technically yes if you use a USB-A splitter, but the 10W output is not enough to fast-charge a modern smartphone while servicing the watch. In practice, charge the watch first (90 minutes), then swap to the phone. If you need both simultaneously, step up to the Nomad 20 or pair the Nomad 10 with a buffer battery.
Is the Goal Zero Nomad 10 waterproof for trail running in the rain?
The panel face is weather-resistant but the USB ports are not sealed. Goal Zero rates the panel for light rain when the port cover is closed. For sustained downpours, stow the panel and switch to a stored power bank like the Amazon Basics 10,000 mAh until the weather clears.
How does the Nomad 10 compare to the BioLite SolarPanel 10 for trail running?
Both panels output a nominal 10W, but the BioLite includes an integrated kickstand and sundial for aiming, which adds 2 ounces. The Nomad 10 is lighter and folds flatter against a running vest. For runners who deploy at lunch breaks, the BioLite's aiming tool wins. For runners who charge while moving, the Nomad 10's lower profile is better.
Does the Coros Pace 3 actually need solar charging on most races?
For races under 50 miles, no — the Pace 3 has 38 hours of GPS battery life and most runners finish before that runs out. Solar charging matters for 100-milers, multi-day expeditions, FKT attempts, and any unsupported objective lasting more than 30 hours. For those efforts, the goal zero nomad 10 trail runners coros pace 3 combination is hard to beat on weight and reliability. See our power bank vs solar panel comparison for more.
