Essentials & Checklists
Comprehensive packing guides for Nepal trekking — from complete route-specific checklists and power bank regulations to water purification methods and the rent-vs-buy decision. Everything you need to pack, and nothing you don't.
Packing Strategy for Nepal Trekking
Every item that goes in your pack will be carried by you or your porter for the entire duration of the trek. This simple fact should drive every packing decision. The goal isn't to pack everything you might need — it's to pack only what you will actually use, at the lightest weight possible, organized so that what you need during the day is in your daypack and what you need at night is accessible in your duffel.
A realistic target for porter-supported trekking is a daypack of 8–12kg (including 2L of water, rain jacket, layers, snacks, and electronics) and a duffel of 10–15kg for the porter. Many trekkers arrive with 20kg+ duffels — porters can carry this, but it strains their bodies and most agencies have a 15kg maximum weight limit for ethical reasons. A heavy duffel almost always means items you never used.
Water purification deserves special attention as a safety system, not just a convenience. Tap water from tea house sources in Nepal is not safe to drink untreated. Gastrointestinal illness is among the most common reasons trekkers fail to complete their planned routes — it's debilitating at altitude when your body is already stressed. Having two methods of water purification (for example, a squeeze filter and iodine tablets as backup) means you always have a working system even if one fails. Buying single-use plastic water bottles throughout a trek generates significant waste in communities that have no waste management infrastructure.
Power and electronics management has become increasingly important as trekkers rely on smartphones for navigation, photography, and communication. Altitude cold reduces battery life significantly — a phone that lasts a full day at sea level may die after 4 hours at -10C. Keeping your phone and power bank warm (in an inner jacket pocket rather than a pack outer pocket) extends their useful life dramatically. The 20,000mAh power bank recommendation is based on the fact that many tea houses above 4,000m charge $2–5 per device for charging from a shared solar or generator power supply — carrying your own power bank is both more reliable and less expensive.
First aid and health items are the category most trekkers under-pack. The minimum essential kit includes: blister care (moleskin, wound pads), pain relief (ibuprofen and paracetamol), anti-diarrhoeal medication, oral rehydration salts, altitude medication (Diamox — consult your doctor before use), and a SAM splint and bandage for ankle injuries. Items specific to Nepal: iodine tablets or water purification drops as backup, and a written list of your blood type, medications, and emergency contact details stored separately from your passport.
The rent-vs-buy decision should be made item by item rather than as a blanket policy. Footwear and base layers are always worth owning. Sleeping bags and down jackets become worth owning if you trek twice or more. Trekking poles, duffel bags, and sleeping pads are almost always worth renting for a single trip given the quality and low cost of Kathmandu rental options.

Frequently Asked Questions
Are power banks restricted on flights to Nepal?
Power banks are subject to airline carry-on restrictions based on their watt-hour (Wh) capacity. Most airlines follow IATA regulations: power banks up to 100Wh (approximately 27,000mAh at 3.7V) are permitted in carry-on baggage without restriction. Banks between 100–160Wh require airline approval but are generally permitted. Banks over 160Wh are prohibited. For Nepal trekking, a 20,000mAh power bank (approximately 74Wh) is well within the limit and the most practical size — it charges a smartphone 4–5 times and a camera battery 2–3 times without being excessively heavy. Power banks must always travel in carry-on luggage, never in checked baggage. Confirm with your specific airline before travel as policies occasionally vary.
What is the best water purification method for Nepal trekking?
Three methods work well for Nepal trekking, each with trade-offs. Iodine or chlorine tablets are the lightest option (20g) and reliably kill bacteria and viruses — the main downside is the chemical taste and the fact that they don't filter sediment. A squeeze filter (Sawyer, LifeStraw) removes bacteria and protozoa but not viruses, and adds negligible weight. A UV pen (SteriPen) kills all pathogens including viruses in 60 seconds of treatment — requires batteries or USB charging and doesn't work in turbid water. The most robust combination for Nepal (where water sources can include both sediment and biological contamination) is a squeeze filter to remove sediment and particles, followed by UV treatment or chemical tablets to neutralize viruses. Many tea houses sell bottled water but this generates significant plastic waste — carrying a reusable bottle with purification capability is strongly preferred.
Should I rent or buy gear for a one-time Nepal trek?
For a single Nepal trek, renting the expensive, bulky items in Kathmandu is almost always the better financial decision. A down jacket, sleeping bag, trekking poles, and duffel bag rented for 14 days costs approximately $30–40 total — versus $400–700 to purchase comparable quality new. Items worth buying even for a single trip include trekking boots (fit is too critical to risk with rental footwear), base layers and socks (hygiene), and rain jacket (which doubles as everyday travel wear). Items worth renting: down jacket, sleeping bag, duffel, and trekking poles. This approach also dramatically reduces luggage weight and baggage fees. If you plan to return to Nepal or use gear for other outdoor pursuits, the calculus shifts toward buying — quality trekking gear lasts 10+ years with care.
What electronics should I bring on a Nepal trek?
The most useful electronics for Nepal trekking are: a smartphone (navigation via Maps.me or Gaia GPS downloaded offline, camera, communication), a 20,000mAh power bank, a universal travel adapter (Nepal uses Type C, D, and M sockets), and a dedicated camera if photography is important to you (Himalayan light is extraordinary). Optional but useful: an e-reader loaded with books for rest days, a satellite communicator (Garmin inReach) for remote routes or solo trekking, and wireless earphones for long trail days. What to leave home: a laptop (heavy, impractical, and vulnerable in tea house conditions), a heavy camera tripod (some trekkers carry a small GorillaPod), and multiple charging cables — consolidate to USB-C where possible.
What do most trekkers forget to pack for Nepal?
The most commonly forgotten or underestimated items reported by returned Nepal trekkers are: moleskin or blister plasters (blisters on day 2 can derail an entire itinerary), lip balm with SPF (altitude sun and dry air destroys lips rapidly), a headlamp with fresh batteries (power cuts are common in tea houses and early starts require a headlamp), high-SPF sunscreen (UV intensity increases roughly 4% per 300m altitude gain), trekking poles (many trekkers decide they don't need them and regret it on the descents), and a small padlock for daypack zippers in tea houses. Also commonly underestimated: the number of snacks needed for the trail — tea house snacks are available but expensive at altitude, and having your own emergency food supply is important for long push days.
What is a realistic complete packing list for a Nepal trek?
A complete packing list for a standard 10–14 day Nepal tea house trek covers four categories. Clothing: 2 base layer shirts, 2 pairs base layer pants, 3 pairs hiking socks, 1 fleece mid-layer, 1 down jacket, 1 hardshell rain jacket, 1 pair trekking pants (zip-off), 1 pair camp shorts, 1 warm hat, gloves, balaclava, sun hat, buff/neck gaiter, camp shoes. Equipment: daypack (25–30L), duffel for porter (60–70L), sleeping bag (-10C to -15C), trekking poles, headlamp, sunglasses, water bottles (1L x2), water purification. Essentials: passport and permit copies, first aid kit (blister care, altitude medication, imodium, ibuprofen), power bank, universal adapter, phone with offline maps, sunscreen SPF50+, lip balm. Optional: camera, e-reader, portable bluetooth speaker, small padlock.
