Nitecore NB10000 vs Anker Power Bank: Grams per Watt Hour
Both hold roughly 10,000 mAh. The Nitecore weighs around 150 g and the Anker around 210 g, so the ultralight bank saves roughly 60 g for about 35 dollars more. That is a reasonable price per gram by ultralight standards, and it is the sort of saving worth taking once the obvious weight has already been cut elsewhere.

Choose the Nitecore NB10000 Gen 2 power bank if…
Choose the Nitecore if your base weight is already tight and you are working through the last easy savings. Sixty grams for a modest step up in price is a better rate than most ultralight upgrades offer, and unlike a shelter or an insulation change it costs you nothing in safety margin. The carbon composite case is also genuinely tough, which matters for something that lives loose in a pack.

Choose the Anker 10,000 mAh portable charger, USB-C if…
Choose the Anker if the budget is better spent elsewhere, which for most people it is. Sixty grams is roughly a tenth of what a lighter shelter might save, at a fraction of the cost. If your base weight is still in double digit pounds, the power bank is not where the win is. Buy the cheap one, cut weight where it is measured in hundreds of grams, and revisit this later.

Frequently asked questions
What capacity do you actually need?
Work it out rather than guessing. A modern phone battery is roughly 4,000 to 5,000 mAh, and charging losses mean a 10,000 mAh bank delivers closer to two full phone charges than three. Add a headlamp and a watch if you carry them. For most trips of up to five days with the phone in aeroplane mode, 10,000 mAh is comfortable.
Does cold affect a power bank?
Yes. Lithium cells deliver less in the cold and charge slowly or not at all below freezing. On a cold trip, keep the bank inside your jacket during the day and in your quilt at night, and charge devices in the evening when everything is still warm rather than first thing on a frozen morning.
Is a solar panel a sensible alternative?
Rarely for backpacking. Panels light enough to carry produce very little in real conditions, especially under tree cover or cloud, and they need to be aimed and kept still to work well. For most trips a larger battery is lighter and more reliable than a panel plus a smaller battery. Long remote traverses with reliable sun are the exception.
Can you take these on a plane?
Power banks must travel in the cabin, never in checked baggage, and airlines apply limits based on watt hours. A 10,000 mAh bank is comfortably inside the usual allowance, but the rules vary by carrier and by country and they change. Check the airline's current guidance before flying rather than relying on what was true last time.
How we choose: we compare published manufacturer specifications, listed weights, and verified owner reviews across retailers. We do not test gear in person, and every weight quoted here is the manufacturer's figure unless we say otherwise, so weigh your own kit before you trust a total. Going lighter also means carrying less margin, so treat insulation, navigation, water treatment and an emergency plan as fixed costs rather than places to save grams.
