Yes, the Anker 625 solar panel can reliably charge a Garmin inReach Mini 2 on the Pacific Crest Trail, and the anker 625 garmin inreach mini 2 pct combination has become a quiet favorite among thru-hikers who want a no-fuss top-up between resupply stops. The 21W panel pushes around 1.0A to 1.5A in clear High Sierra or SoCal sun, which is enough to bring the Mini 2's small 1,250 mAh battery from 30% to full in roughly 90 minutes of strapped-to-the-pack hiking. Pair it with a lightweight buffer battery and you can comfortably send daily check-ins, weather queries, and the occasional SOS confirmation without ever scrambling for a town outlet.
Below we cover real-world charge rates on the trail, where the Anker 625 outshines the Goal Zero Nomad and BigBlue alternatives, and which compact power banks pair best for stretches between Kennedy Meadows, Sierra City, and Cascade Locks in 2026.

Top Picks
The Anker 625 Solar Panel is a 21W, 3-fold monocrystalline panel that weighs about 20.3 oz (576 g). For the PCT, that weight is the upper edge of what most thru-hikers tolerate, but it earns its place because of three things: it has dual USB-A ports with smart IQ output, it folds to roughly the size of a paperback against the back of a 50L pack, and it is tough enough to survive being lashed to bear-canister-laden trampoline mesh on Forester Pass approaches.
Most importantly, the inReach Mini 2 charges through USB-C at a modest 5V/1A. The Anker 625 has no problem keeping that current steady once the angle is decent. You don't need MPPT controllers or PD trickery; just clip the panel on, plug in your buffer bank, and walk.
Realistic charge expectations between resupply boxes
Between Warner Springs and Idyllwild (about 100 trail miles), most hikers send 6-10 messages a day and burn maybe 25% of the Mini 2's battery. With the Anker 625 strapped to the pack from 9 a.m. to noon in SoCal exposure, you'll bank enough power to refill the Mini 2 twice over from a small buffer cell. The story changes in Washington's drizzly North Cascades, where panel output can drop to 30% of rated wattage; that's why a buffer battery is mandatory, not optional, for the full thru-hike.
Recommended power banks to pair with the Anker 625
Direct sun-to-Mini-2 charging is fine on long ridgewalks, but the panel will cycle the device's charging electronics every time a cloud passes overhead, which Garmin warns against. The fix is universally accepted on the trail: charge a buffer power bank during the day, then top off the Mini 2 from the bank at camp. Here are the best 2026 banks for that role.
YELOMIN 38800mAh Solar Power Bank — best ultralight all-rounder
The YELOMIN gives you 38,800 mAh of headroom for very little weight relative to capacity, and the USB-C PD input means you can recharge it from any caretaker outlet in under five hours during your zero day. The built-in mini panel is symbolic; don't count on it as primary charging, but the bank's USB-C output is rock-solid for the Mini 2 at 5V/1A. The weather-resistant housing tolerates a brief afternoon thunderstorm if you forget to stash it under your pack lid. YELOMIN 38800mAh Solar Power Bank.
SOARAISE Solar Power Bank 48000mAh — best for trail couples
If you're hiking with a partner who also runs a Mini 2 or wants to top up a phone for offline Far Out maps, the SOARAISE 48,000 mAh has the headroom for both. It also features Qi wireless on top, which is handy for sharing a charge with a buddy's iPhone over breakfast. At roughly 1.4 lb it is heavier than what solo UL hikers will accept, but for a pair splitting one buffer between them, it's an efficient weight share. SOARAISE Solar Charger Power Bank.
Nymzixt 49800mAh Solar Power Bank — best for the Sierra carry
The 211-mile Sierra stretch from Kennedy Meadows to VVR is the one section where most thru-hikers regret carrying anything less than 45,000 mAh of buffer capacity. The Nymzixt 49,800 mAh hits that mark and includes Qi wireless. Pair it with the Anker 625 strapped to the pack on alpine days and you'll keep both your Mini 2 and your phone fully topped through Whitney summit, Mather, and Muir Pass without anxiety. Nymzixt Solar Power Bank 49800mAh 22.5W QC3.0 Fast Charging Built in 4.
Amazon Basics High-Capacity Portable Charger — best budget buffer
Not every thru-hiker wants to spend $80 on a power bank that will get scuffed within 200 miles. The Amazon Basics High-Capacity Portable Charger delivers an honest charge profile, supports USB-C in/out for fast resupply-day topping, and weighs in at a respectable mid-range. For PCT hikers who already invested in the Anker 625 itself, this is the no-drama buffer pick. Amazon Basics High-Capacity Portable Charger Power Bank with 3-Port.
Portable Solar Generator 300W with Foldable 60W Panel — for resupply town stops only
This is not a trail-carry product; it's far too heavy. But if you have a support person bouncing a Bear Vault and a resupply box to Kennedy Meadows, Mammoth, or Stehekin, having a 300W solar generator parked at the trail-angel house turns it into a charging hub for your Mini 2, headlamp, and even an inflatable pad pump. It's a niche pick, but worth mentioning for assisted thru-hikes. Portable Solar Generator.

How to actually mount the Anker 625 on a PCT pack
Two strap configurations work reliably. The first is the “lid sandwich” — slip the folded panel between your pack lid and the brain, leaving the active panel face up. This works for ULA Circuits, Hyperlite Southwests, and Gossamer Gear Mariposas. The second is the back-panel daisy-chain mount: clip the panel's grommets to the back-panel webbing using two mini carabiners, then dangle your power bank in a side mesh pocket. Both setups expose the full panel surface even when you crouch under blowdowns.
One pitfall: don't strap the Mini 2 directly to the panel via a short cable. Vibration from trekking-pole rhythm slowly works the USB-C connector loose. Charge a buffer bank instead and refill the Mini 2 at camp via a short, kink-free cable.

Heat management above 9,000 feet
Above tree line — Forester, Glen, Muir, and Pinchot passes — direct sun on a 21W panel laid flat on dark rock can heat the Anker 625's USB-A output and your buffer bank's casing to over 50°C (122°F). Most banks throttle current at that temperature. The fix: prop one edge of the panel on a small stone so air flows underneath, and keep the bank in shade inside a side pocket while the cable runs over the top.
If you're using the anker 625 garmin inreach mini 2 pct setup in the snow-recovery sections of NorCal, snow glare on alpine lakes can actually push panel output 10-15% above rated wattage for brief windows. Don't waste those; drop pack on a Mahogany Flat lunch break and prop the panel toward the sun.
Frequently Asked Questions
How long does the Anker 625 take to fully charge a Garmin inReach Mini 2?
From a fully drained Mini 2 (1,250 mAh battery), the Anker 625 in direct overhead sun delivers a full charge in approximately 80-100 minutes. In partly cloudy SoCal-style conditions, expect 2-3 hours. Don't expect a full charge during back-of-pack hiking unless the panel sits flat on the lid and the sun is high; angled mounts cut output substantially.
Is the Anker 625 better than the BigBlue 28W for PCT thru-hiking?
The BigBlue 28W produces more wattage at peak, but it's also longer and heavier when folded. For Mini 2-only charging needs, the Anker 625's 21W is more than enough, and the smaller fold pattern fits better against ULA and HMG pack lids. If you're also charging a phone for Far Out, the BigBlue's extra headroom helps; for Mini-2-plus-buffer-bank workflows, the Anker wins on pack ergonomics.
Can the Anker 625 charge the Mini 2 directly without a buffer battery?
Technically yes, but Garmin strongly recommends against it. Every passing cloud causes the panel voltage to dip, which forces the Mini 2's charging IC to renegotiate, and over a thru-hike that wears out the cell chemistry faster. Use a buffer bank — your battery longevity will thank you 2,650 miles later.
Will the Anker 625 still work in rainy Washington sections of the PCT?
The panel is IPX4-rated, so it tolerates rain in transit but you won't get usable charge from overcast skies. In the Goat Rocks and Glacier Peak Wilderness sections, plan to enter with a near-full buffer bank from Stehekin or White Pass. The Anker 625 should ride packed inside your dry bag during sustained rain, not strapped externally.
What is the lightest realistic charging kit for the PCT with a Mini 2?
For ultralight hikers: Anker 625 (20.3 oz) plus a 10,000 mAh USB-C power bank (~6 oz) plus one 6-inch USB-C cable. Total kit weight under 27 oz. For longer Sierra carries, swap in a 25,000-30,000 mAh bank and skip the panel for that section if your resupply stops are tight. See our ultralight power bank guide for trail-tested picks.
Does the Anker 625 work with USB-C PD devices?
The Anker 625 has dual USB-A outputs only — no USB-C. That's actually fine for the Mini 2 (use a USB-A to USB-C cable) and for most power banks (which accept USB-A 5V input even when they prefer PD). If you also carry a USB-C-only phone like a Pixel 8, plan to charge it indirectly via the buffer bank, not the panel. Compare Anker 625 vs. BigBlue here.
Where should I send the Anker 625 on my PCT resupply boxes?
Most thru-hikers carry the panel start-to-finish, but if you're flip-flopping or want to ditch it through dense Oregon forest, send it ahead from Ashland to Cascade Locks. Many hikers also bounce it from Kennedy Meadows South to Mammoth and pick it back up if they cached an extra power bank for the Sierra. More resupply strategies here.
Final thoughts
The anker 625 garmin inreach mini 2 pct combination isn't glamorous, but it has earned thousands of completed thru-hikes. Pair the 21W panel with a USB-C buffer bank in the 30-50k mAh range, mount it flat on your pack lid, and never charge the Mini 2 directly from a fluctuating solar input. If you're walking northbound in 2026, that simple rig will keep your satellite messenger alive from Campo to Manning Park.
