A 26,800mAh / 99Wh hiking phone charger you fill at home, carry in the pack, and use for phones, GPS-style USB devices, and cameras on the trail — with IP66 weather protection and realistic solar top-off.
USB-C, dual USB-A, and 10W wireless — up to three devices at once
IP66-rated protection for rain, dust, and trail use
Built-in solar tops off in sun; a short high-current cable and lanyard are included
Is this a good power bank for hiking and backpacking?
Yes — if you want high capacity in the backpack, not the lightest possible 10,000mAh brick. The Portable Solar Power Bank stores 26,800mAh / 99Wh. Recharge it through USB-C in about 4 to 5 hours before you hit the trail. A short high-current charging cable and a lanyard are included. On trail, use USB-C, USB-A, or 10W wireless. The built-in panel is 5.93 × 2.81 in at 300mA/h — supplemental charging in direct sunlight, not a foldable solar generator. For more sun harvest, add KEUTEK’s 40W Portable Solar Panel.
Capacity versus portability
Enough stored energy for phones, GPS, and cameras
With a PD fast charging cable through USB-C, the pack can charge an iPhone 16 up to 5 times, an iPhone 15 up to 5 times, a Galaxy S24 up to 3 times, or an iPad Mini up to 3 times. Those are single-device estimates. Actual results vary based on device, battery condition, usage, temperature, and charging method. Hikers using maps, photos, and a USB camera or GPS unit will use stored energy faster than a single-phone count — this capacity is built for that mixed load, not for a fridge or AC gear.
Built for the Backpack, Ready for the Trail
With a 26,800mAh / 99Wh capacity, this power bank is built for hikers who prioritize dependable power over ultralight weight. Its 6.93 × 3.74 × 1.14 in design fits easily in a backpack and can also be secured with the included lanyard. It is especially well suited for overnight and multi-day trips where having more charging capacity for phones, navigation devices, and other essentials matters more than shaving off a few ounces.
Built for the trail
IP66-rated protection helps guard against rain, splashes, dust, and everyday outdoor conditions. Fire-resistant casing, dust-proof and shockproof construction, a four-light LED charge indicator, and a flashlight with flashlight, dim, SOS, and strobe modes (up to 50 hours of light). It is not designed for submersion.
Realistic Solar Support on the Trail
The integrated solar panel provides up to 300mA of supplemental charging in direct sunlight, making it useful for extending your available power while you’re outdoors. For the best results, fully charge the power bank via USB-C before your trip, then position the solar panel toward the sun when conditions allow. Need faster solar charging? Pair it with KEUTEK’s 40W Portable Solar Panel.
How hikers actually use it
Fill at home. Charge devices in camp. Top off in sun.
Start with a full USB-C charge (about 4 to 5 hours). On trail, keep the phone on a PD USB-C cable when you need navigation or photos, or use wireless through a compatible case. Charge a second device on USB-A at the same time — up to three devices total. Hang the bank on the pack with the included lanyard when you want solar top-off. Lithium-polymer chemistry, 99Wh, certifications CE/FCC/RoHS/MSDS/UN38.3.
How hiking charging works
Wall → pack → phone, GPS, camera → optional sun
1. Fill the pack at home. USB-C input: 12V/1.5A, 9V/2A, 5V/3A. USB-C recharging takes about 4 to 5 hours. Use the included short high-current charging cable. Micro-USB input: 9V/2A, 5V/2.4A. A 65W wall charger is sold separately.
2. Power trail devices. USB-C output uses the same voltage table and also charges a phone. Dual USB-A covers USB-A GPS units, cameras, and headlamps that use USB. Wireless is 10W / 7.5W / 5W for compatible iPhone, Galaxy, and Pixel phones.
3. Choose the trail cable. ProSeries Max is a magnetic-tip cable (USB-C 240W or USB-A 18W variants). Sovix is a 100W fixed-tip USB-C cable for phones, tablets, laptops, and power banks without magnets.
Day hike with navigation. Start full. One high-capacity bank covers heavy map and photo use with margin.
Overnight / weekend backpacking. Phones, a USB GPS or camera, and lights from USB-C and USB-A. Solar is supplemental in open sun.
Longer sections between outlets. Same bank plus the 40W panel if you want more sun harvest. For AC camp loads, choose the 300W Portable Power Station Max.
Travel to the trailhead. 99Wh lithium-polymer design for carry-on portable batteries — confirm airline rules before you fly.
