The Best Power Banks and Charging Kit for Bikepacking

The 5V/2.4A output is the honest limitation. That is standard-speed charging, not USB-C Power Delivery, so a modern phone will take considerably longer to fill than it would from a PD charger — an overnight-at-camp charge rather than a coffee-stop top-up. Recharging the bank itself is likewise slow. If your routine is to plug in at a cafe for 40 minutes and leave with a full phone, you want a PD unit instead. If you charge overnight while you sleep, the speed is irrelevant and the weight saving is not.

The wireless charging feature is genuinely useful at camp: you can drop your phone on top of the bank while eating dinner without fumbling for a cable in low light. Transfer speeds are predictably slower than wired, but for an overnight camp charge it makes no practical difference. The main limitation is that 10,000mAh won't cover a 5-7 day expedition without very aggressive power management. For those trips, a 20,000mAh bank or a dynamo hub charging setup is more appropriate. For a 3-4 day tour, this hits the right balance of capacity and packability.

The comparison to make is against a plain 10,000mAh bank, which costs roughly half this and weighs about the same. What the extra money buys is magnetic wireless charging, and it is worth being clear-eyed about that on a bike tour: wireless charging is materially less efficient than cable, so the same 10,000mAh delivers noticeably fewer full phone charges when used that way.

Where it does earn its place is the magnet itself — the pack sits stuck to the back of the phone in a frame bag with no cable to work loose over rough ground, which is the failure that leaves you at camp with an empty phone and a bank that never discharged. The USB-C and USB-A ports mean you can use it as a conventional bank when efficiency matters and the magnet when convenience does. At ~185g for 10,000mAh it is a reasonable three-to-four day supply for a phone and a head unit.

The 5,000mAh capacity provides roughly one full charge for a modern smartphone, which is perfect for a 24-48 hour trip where you only need to keep your GPS and phone alive. The build quality is standard Anker, solid, reliable, and equipped with ActiveShield safety tech to prevent overheating.

One major advantage is that it clips directly into your device, making it possible to charge while you're actually riding without cables flapping in the wind. It is the cleanest power setup available for short, fast-paced trips where bulk is the constraint.

There is an awkward comparison to make here. The Anker 10,000mAh on our beginners list holds twice the charge for $21.99 — four dollars less than this — and weighs 180g against 100g. Per gram the two are within ten percent of each other; per dollar the bigger one wins outright.

So the case for the Nano is not capacity or value, it is the fold-out USB-C connector. No cable, nothing to lose, nothing to fray at the port — and on a minimalist overnighter where the entire electronics kit is a phone and a headlamp, that is a real simplification. 5,000mAh is roughly one full phone charge plus a headlamp top-up, which is the right size for one night out and clearly not enough for three. Buy it for the form factor or don't buy it.
