Best Bikepacking Electronics: Power Banks, Solar Panels, and Dynamos

The Power Problem

Modern bikepacking runs on electronics. Your GPS, phone, lights, camera, and headlamp all need power, and once you leave civilization there are no outlets. Managing your power supply is one of the most important logistical challenges of multi-day riding, and getting it wrong can leave you without navigation, communication, or safety lighting in remote terrain.

The good news is that the available solutions have improved dramatically. Between high-capacity power banks, efficient solar panels, and dynamo hubs that generate power from your pedaling, there is a solution for every trip length and riding style. The key is matching your power consumption to your power generation and storage.

Running a Power Audit

Before choosing a power solution, calculate your daily power consumption. Here are typical draws for common bikepacking electronics:

• Smartphone (GPS + maps): 2,000-3,000 mAh per day with airplane mode and battery saver on
• Dedicated GPS unit: 500-1,500 mAh per day depending on model
• Bike headlight (per charge): 2,000-4,000 mAh depending on brightness and runtime
• Headlamp: 500-1,000 mAh per charge
• Camera (action cam): 1,000-2,000 mAh per day of moderate use
• Satellite communicator: 500-1,000 mAh per day with tracking

A typical bikepacker running a phone for navigation, a headlamp, and occasional bike light use needs about 3,000-5,000 mAh per day. Over a five-day trip without resupply, that is 15,000-25,000 mAh of battery capacity needed.

Best Power Banks for Bikepacking

Anker PowerCore 10000

The Anker PowerCore 10000 is the bikepacking community's default power bank, and for good reason. At 180 grams, it packs 10,000 mAh of capacity into a pocketable package smaller than a deck of cards. That is enough for 2-3 full smartphone charges or about 3-4 days of moderate GPS use with power-saving practices.

The single USB-A output delivers 12W of power, which is fast enough for overnight charging of any device. The bank itself recharges in about 4 hours via Micro-USB or USB-C depending on the version. The build quality is excellent, and Anker's reputation for accurate capacity ratings means you get the full 10,000 mAh advertised.

For trips of 2-4 days with access to town charging, a single PowerCore 10000 is all most riders need. For longer trips, carry two.

Nitecore NB10000

For weight-obsessed bikepackers, the Nitecore NB10000 offers 10,000 mAh at just 150 grams, making it one of the lightest power banks per milliamp-hour available. The carbon fiber construction looks and feels premium, and the dual USB-C and USB-A outputs provide flexibility. The slim profile fits perfectly in a frame bag alongside other items.

Solar Panels: Pros and Cons

Goal Zero Nomad 10

The Goal Zero Nomad 10 is a 10-watt folding solar panel designed for mobile charging. It outputs enough power to slowly charge a phone in direct sunlight, and it folds to a relatively compact size for strapping to a handlebar bag or seat bag.

Here is the honest reality of solar charging for bikepacking: it is supplemental at best. A 10-watt panel in ideal direct sunlight might produce 5-7 watts of usable power. That means roughly 4-5 hours of direct sun to fully charge a phone. Factor in clouds, tree cover, suboptimal angles, and the fact that you are often riding through shade, and real-world output drops significantly.

Solar works best on long tours through open, sunny terrain. Riders crossing deserts, grasslands, or open mountain passes get real value from a panel. Riders in forested areas or rainy climates often find the weight and hassle not worth the trickle of power produced.

When Solar Makes Sense

• Multi-week tours with limited resupply
• Routes through open, sunny terrain
• Summer riding with long daylight hours
• As a supplement to a power bank, not a replacement

Dynamo Systems: Unlimited Power

Sinewave Cycles Reactor

The Sinewave Cycles Reactor is a dynamo-powered USB charger and headlight in one unit. Paired with a dynamo hub like a Son or Shutter Precision, it converts your pedaling into electrical power that charges devices and runs your lights simultaneously. Above about 10mph, it produces a steady 5 watts of USB power, enough to keep a phone or GPS topped up while riding.

The Reactor is built in the USA with exceptional attention to detail. The daytime mode diverts all power to USB charging when you do not need the light. The nighttime mode splits power between a bright headlight and USB output. The system is weatherproof, shockproof, and requires essentially zero maintenance.

The biggest advantage of dynamo power is freedom from battery anxiety on long tours. You never need to find an outlet, carry heavy power banks, or ration your GPS use. You just ride and your devices stay charged.

Exposure Lights Revo Dynamo

The Exposure Revo Dynamo is a premium dynamo headlight with a built-in cache battery that stores power for use at stops. The beam quality is exceptional, with a well-shaped cutoff that illuminates the road without blinding oncoming traffic. The standlight feature keeps the light glowing at intersections, which is a critical safety feature for road riding.

Paired with a separate USB charging unit, a dynamo hub can run both your lights and your charging needs indefinitely.

The Dynamo Tradeoff

Dynamo hubs add about 400-500 grams to your wheel and create a small amount of drag even when not generating power (about 1-3 watts on modern hubs). The upfront cost is significant: a quality hub, wheel build, and charging unit typically runs $400-700 total. But for long-distance touring and multi-week bikepacking, the investment pays for itself in eliminated power bank weight and charging hassle.

Phone Mounts and Protection

SP Connect Bike Bundle

If you use your phone for navigation, a quality mount is essential. The SP Connect system uses a twist-lock mechanism that is rock solid on rough terrain. The phone case is slim enough for daily use, and the mount attaches and detaches in one second. Various mount options work with stems, handlebars, and out-front adapters.

Important warning: prolonged vibration from rough trails can damage your phone's camera stabilization hardware. If your route includes significant rough riding, consider using a dedicated GPS unit instead of your phone, or mount your phone on a vibration-damping adapter.

Power-Saving Tips

The cheapest, lightest power is the power you do not use. These habits can double your battery life:

• Airplane mode: Your phone searching for cell signal is the biggest battery drain. Use airplane mode with GPS enabled for navigation.
• Screen brightness: Turn it down as far as you can read. Auto-brightness uses the sensor, which itself draws power.
• Offline maps: Download maps before the trip so your phone does not need data connections.
• Battery saver mode: Enable your phone's power-saving features from the start, not when the battery is already low.
• Charge at every opportunity: Hit a cafe with outlets? Plug in. Even 30 minutes of charging adds meaningful capacity.
• Turn off unused devices: Only power on cameras and satellite communicators when actively using them.
• Keep batteries warm: Cold temperatures reduce battery capacity. Sleep with your power bank and keep devices inside your jacket in cold weather.

Recommended Power Setups by Trip Length

Weekend Overnighter (1-2 days)

A single Anker PowerCore 10000 handles weekend trips easily. Start with all devices fully charged and you will likely not even drain the power bank.

Week-Long Trip (3-7 days)

Two 10,000 mAh power banks, aggressive power-saving habits, and charging at any resupply stop. If your route passes through towns, you can likely get by with a single bank and opportunistic charging.

Multi-Week Tour (7+ days)

This is where dynamo power shines. A Sinewave Cycles Reactor with a dynamo hub eliminates battery management entirely. Supplement with a single 10,000 mAh bank as a buffer for rest days when you are not riding.

Alternatively, a 20,000+ mAh power bank paired with a Goal Zero Nomad 10 solar panel works for tours through sunny terrain, though this combination is heavier than a dynamo setup and weather-dependent.
