Nitecore NB10000 Gen 3 — Two phone charges for the weight of a phone
Best overall

Two phone charges for the weight of a phone

Nitecore NB10000 Gen 3

10,000 mAh (~37 Wh), carbon fibre, ~150 g

The best capacity-per-gram you can buy and it clears every airline limit without a conversation — 10,000 mAh is about two phone charges, so on a fortnight above the solar line you will still be paying a lodge occasionally.

Half the weight of a comparable bank

Well under the 100 Wh cabin-baggage line

USB-C in and out, one cable for everything

Only two phone charges

Carbon shell scratches

Loses noticeable capacity below freezing — sleep with it

Not for you if: A camera-heavy trip or a group sharing one bank. Take the 20,000 mAh instead.

Energizer Ultimate Lithium AAA — The only AAA that still works at −15 °CBest in cold

The only AAA that still works at −15 °C

Energizer Ultimate Lithium AAA

Alkalines lose most of their usable capacity in real cold and a headlamp dies mid-descent; lithium does not, and it costs roughly three times as much per cell.

Universal travel adapter with USB-C (Type C/D) — Nepal runs Type C, D and M — your plug fits none of themEssential

Nepal runs Type C, D and M — your plug fits none of them

Universal travel adapter with USB-C (Type C/D)

A universal adapter with its own USB-C ports means one wall socket charges three things, which matters when a lodge has exactly one and six guests — the cheap ones have no fuse, so do not run a laptop through it.

BigBlue 28W Solar Charger — For expedition camps where there is no lodge at allBest panel

For expedition camps where there is no lodge at all

BigBlue 28W Solar Charger

Genuinely charges a power bank in a Himalayan day of clear sun, which is a real advantage on a camping trek — on a teahouse trek it is 670 g replacing a service that costs a few dollars.

Black Diamond Spot 400 — The 4 a.m. start and the walk to the toilet blockBest overall

The 4 a.m. start and the walk to the toilet block

Black Diamond Spot 400

Bright enough for a pre-dawn pass and simple enough to fix in the dark with cold hands — it runs on AAAs, which is heavier than a rechargeable and is exactly why we recommend it.

LuminAID Nova Inflatable Solar Lantern — Light for a whole table, not a single beamBest lantern

Light for a whole table, not a single beam

LuminAID Nova Inflatable Solar Lantern

Turns a dark dining room into somewhere you can play cards, and it charges itself hanging off the back of a pack — the panel is small, so treat solar as a top-up rather than a charger.

On your keys, for the night you cannot find your headlamp

Nitecore TINI 3 Keychain Light

Absurdly bright for something the size of a thumb, and it lives on the keyring you already carry — the runtime at full brightness is measured in minutes, not hours.

Anker Power Bank 20,000 mAh — A fortnight off-grid without paying for lodge chargingBest capacity

A fortnight off-grid without paying for lodge charging

Anker Power Bank 20,000 mAh

Four to five phone charges, which is genuinely a whole Everest Base Camp trek without ever paying a lodge — you carry 350 g up to 5,545 m to save perhaps twenty dollars.

Petzl Actik Core — For people already carrying a power bankBest rechargeable

For people already carrying a power bank

Petzl Actik Core

The hybrid design is the honest compromise: charge it off your bank most nights, drop in AAAs when the solar has failed for three days — you pay more than either single-format lamp costs.

The one that survives being crushed in a duffel

Anker PowerLine USB-C Cable

Take two — a failed cable at 4,500 m turns a working power bank into ballast, and this is the cheapest failure in the whole department to insure against.

Black Diamond Astro 300 — The spare that lives in the bottom of the duffelBest backup

The spare that lives in the bottom of the duffel

Black Diamond Astro 300

Cheap and light enough that carrying two lamps stops being an argument — the beam is flat and the strap is thin, so it is a backup and not a main lamp.
