There’s a specific kind of quiet panic that comes from watching your phone hit 4% as you’re trying to find a remote bay you’ve never been to, with the light going. No map, no offline notes, no photos, and if something goes wrong, no way to call anyone. Power isn’t a luxury on a camping trip — it’s the thing that quietly underpins navigation, safety and every photo you’ll actually keep.
The trouble is most “best power bank” lists are written for backpackers and ignore the one advantage a motorcycle gives you: a running engine that can charge things all day. So this guide is built around how riders actually stay powered — two layers, and a bit of maths so you buy the right size instead of guessing.
Anker 325 Power Bank 10000mAh
Compact, affordable and reliable — the no-brainer pick for most moto campers.

Think about power in two layers and the whole thing gets simple.
Layer one is the bike. Your engine is a generator. A hardwired USB charger wired to the battery (through a fuse) keeps your phone, GPS and intercom topped up the entire time you’re moving, which on a touring day is most of the day. You arrive at camp with full devices instead of empty ones.
Layer two is the power bank. When the engine’s off — at camp, in the tent, on a rest day — the power bank covers you. It’s your reserve, not your main supply.
Run both and you basically never think about charge again. Run only a power bank and you’ll spend evenings rationing it. The picks below cover both layers: four banks for layer two, and a proper bike-side charger for layer one.
The Battery Maths Worth Knowing
Two numbers stop you from buying the wrong thing.
Real capacity is about 60–70% of the printed number. A 10,000 mAh bank is rated at the cells’ 3.7 V, but your phone charges at 5 V, and the conversion loses energy as heat. So that 10,000 mAh delivers roughly 6,000–7,000 mAh to your phone — call it one and a half charges. A 20,000 mAh bank gives you about three. Size accordingly: 10,000 if you recharge daily, 20,000 if you can’t.
And if you ever fly to a rental: airlines measure in watt-hours, where Wh = (mAh ÷ 1000) × 3.7. So 10,000 mAh = 37 Wh and 20,000 mAh = 74 Wh — both under the 100 Wh carry-on limit, both fine. Anything over 100 Wh needs approval; over 160 Wh is banned. Carry-on only, never checked, and the Wh number has to be printed on the bank.

1. Anker 325 Power Bank — Best for Motorcycle Camping
The Anker 325 Power Bank is the one most riders should just buy and stop thinking about. It’s 10,000 mAh in a compact, pocketable body with both USB-A and USB-C outputs — enough to fully charge a modern phone once and top it up again before you’re back in the saddle. It’s genuinely slim, the price is low enough that you won’t be precious about throwing it in a tank bag, and it’s an Anker, which means it’ll still be working in five years.
It won’t win a spec sheet fight — the output is modest and it’s not weatherproof — but that’s fine. Its job is to refill a phone and a headlamp at camp, not charge a laptop. Paired with a hardwired bike-side charger for the riding day, this covers the overnight reserve layer for the cost of a decent dinner. For most riders doing a week or less with daily charging opportunities, this is simply enough.
Check Anker 325 Power Bank on Amazon →
- Compact and pocketable, easy to carry
- USB-A + USB-C, one charge per night
- Affordable Anker reliability
- Modest 12 W output — not for fast charging
- Not weatherproof — keep in a dry bag
2. Anker 737 PowerCore 24K — Most Capacity
When you carry a laptop, can’t recharge nightly, or just want to stop worrying entirely, the Anker 737 PowerCore 24K is the heavyweight. At 24,000 mAh it delivers roughly three and a half full phone charges in real use, and the 140 W max output will fast-charge a laptop and a phone simultaneously without slowing either down. A smart LED display shows you exactly what’s going in and out, and it refills itself in around 90 minutes at high wattage.
It’s heavier and pricier than the Anker 325, and it’s not weatherproof, so it lives in a dry bag or pannier rather than out on the tank. But for a long trip with serious electronics — GoPro, intercom, GPS, laptop — or for the rider who’d rather carry one substantial bank than nurse two small ones, this is the dependable choice. At 88.8 Wh it’s still under the 100 Wh carry-on limit, so it flies legally in your hand luggage.

- ~3.5 phone charges; fast-charges laptops too
- 140 W out, smart display, fast self-recharge
- Flight-legal at 88.8 Wh
- Heavier and pricier than a basic 10k
- Not weatherproof — keep it in a dry bag
3. ELECOM NESTOUT — Best Rugged / Waterproof
If you ride in genuinely wet, dusty, drop-it-on-rocks conditions, the ELECOM NESTOUT 10000mAh rugged power bank is built for the abuse. It carries an IP67 rating — properly submersible, dust-sealed — in a shockproof shell, with 20 W USB-C output and even a ¼-20 tripod thread on the base for clipping on the brand’s modular lantern and light accessories.
It’s a bit heavier and pricier than a bare 10,000 mAh bank, and that’s the trade for the sealing. But this is the one you can leave clipped to the outside of a bag in the rain, fish out of a muddy pannier, or set down on a wet rock at camp without a second thought. For hard off-road and bad weather, peace of mind is worth the few extra grams.
- IP67 — submersible and dust-sealed
- Shockproof, genuinely rugged
- Tripod mount + modular light accessories
- Heavier and dearer than a basic 10k
- 20 W output is modest
4. YONHAN SAE-to-USB-C — Best Bike-Side Charger
This is layer one — the part that charges while you ride. The YONHAN SAE-to-USB-C motorcycle charger wires to your battery (ideally off an SAE pigtail with an inline fuse) and gives you dual ports — USB-C Power Delivery and Quick Charge 3.0, 60 W total — plus a little LED voltmeter so you can actually see your system voltage. It’s waterproof, has an on/off switch, and the SAE quick-disconnect means you can unplug it for winter or a battery tender in seconds.
The voltmeter is the underrated bit: glance down at a red light and you’ll know if your accessories are pulling more than the bike is making before you flatten the battery. Wiring it is a ten-minute job — SAE lead to the battery, fuse inline, route the port somewhere weatherproof near the bars. For long-distance riders this is the single highest-value upgrade here, because it makes the power banks a backup rather than a lifeline.

- Charges everything while you ride
- USB-C PD + QC3.0, 60 W, built-in voltmeter
- Waterproof, SAE quick-disconnect
- Needs a (simple) wiring install
- Mind your stator's spare wattage on small bikes
5. INIU 45W — Best Budget
The INIU 45W 10000mAh power bank is the easy, cheap pick that doesn’t feel cheap. It’s genuinely slim, has a built-in USB-C cable so there’s one fewer thing to forget, pushes a respectable 45 W of PD fast-charging, and comes with a long warranty. For a rider who wants a reliable one-night reserve without overthinking it, this is plenty.
It’s not weatherproof and it’s not big, so keep it in a dry bag and treat it as a top-up bank rather than a multi-day supply. But as a first power bank, or a backup to your backup, it’s hard to spend your money better.

- Slim, with a built-in USB-C cable
- 45 W PD fast charging
- Cheap, long warranty
- Not weatherproof
- One-night capacity only
How to Choose: A Quick Buying Guide
- Run two layers. Hardwire a charger for while you ride; carry a power bank for camp. That combination is what makes power a non-issue.
- Size by the real number. A 10,000 mAh bank ≈ 1.5 phone charges; 20,000 mAh ≈ 3. Recharge daily → 10k; can’t → 20k.
- Match the bank to the weather. Dry and light → Anker 325 or INIU. Big loads → Anker 737. Wet and rough → NESTOUT.
- Watch your stator on a small bike. USB ~20 W, grips ~37 W, heated jacket ~55 W — add them up against your surplus, and see our heated gear guide before loading a small ADV bike.
- Keep it all reachable. A tank bag with a phone window plus a hardwired port is the cleanest cockpit, and don’t forget the gear checklist so the cables actually make it into the panniers.

Frequently Asked Questions
How many phone charges do you really get from a 10,000 mAh power bank?
Around one and a half full charges for a modern phone — not the two-and-a-bit the number suggests. The rated capacity is measured at the cells' 3.7 V, but your phone charges at 5 V (or higher), and converting between them wastes energy as heat. In practice a 10,000 mAh bank delivers roughly 6,000–7,000 mAh to your device. So a 10,000 mAh pack is a one-night-and-top-up size; if you can't recharge it daily, step up to 20,000 mAh, which gives you roughly three phone charges before it's empty.
Can I take a power bank on a plane?
Yes, if it's under 100 watt-hours and it's in your carry-on. Airlines measure power banks in watt-hours (Wh), not mAh: the formula is Wh = (mAh ÷ 1000) × 3.7. So a 10,000 mAh bank is 37 Wh and a 20,000 mAh bank is 74 Wh — both well under the 100 Wh limit and fine to carry on with no approval. Between 100 and 160 Wh you need airline approval (usually two units max); over 160 Wh is banned from passenger flights. Power banks are not allowed in checked luggage, and the Wh figure must be printed on the bank or you can be stopped at security. If you fly to a rental or tour, this matters.
Will adding a USB charger and heated grips drain my motorcycle's battery?
Only if you ask for more than the charging system can make. A typical bike's stator puts out around 238 watts (roughly 17 amps at 14 volts), and fuel-injected bikes sit around 240–285 watts — but the bike's own lights and electronics already use a chunk of that, so only the surplus is yours. As a rough guide: USB charging draws about 20 W, heated grips about 37 W, a heated jacket about 55 W. Run high beam, grips and all your charging at once and you can be near the limit on a small bike. Add a heated jacket on top and you'll be drawing more than you're making, slowly flattening the battery. Fit an inline voltmeter so you can see system voltage — if it sags below about 12 V at idle, you're over budget.
What's the difference between USB-C PD and Quick Charge?
PD (Power Delivery) is the universal USB-C fast-charging standard that works across phones, tablets and laptops, and the latest version pushes serious wattage. Quick Charge (QC) is Qualcomm's proprietary standard, mainly for phones with Snapdragon chips. PD has become the default — if you buy a charger with USB-C PD you're covered for almost everything, and most chargers worth buying do both anyway. Don't overpay for a 100 W charger to feed a phone that only draws 20–45 W; match the output to what you actually charge.
Do I need bike-side charging or is a power bank enough?
For a weekend with light electronics, a power bank you top up off the bike each day is plenty. The moment you're running a phone for navigation all day plus a GPS, an intercom and an action camera, you'll want bike-side charging — a hardwired USB feed that keeps everything topped up while you ride, with the power bank as your in-tent reserve for the evening. The two-layer setup (hardwired charging while moving, power bank when stopped) is what keeps long trips stress-free, and it's how most experienced overlanders run it.
