Complete Buyer's Guide: How to Choose a Battery Pack for Backpacking
1. Capacity: How Much Power Do You Really Need?
Capacity is measured in milliamp hours (mAh), but what does that actually mean for your trip? For most backpackers, 10,000mAh is the sweet spot – it can charge a smartphone 2-3 times, which is perfect for weekend trips. If you’re going out for longer or need to power multiple devices, look for 20,000-25,000mAh. Anything above 30,000mAh starts getting heavy, so only consider these if you’re car camping or have specific high-power needs.
Remember that actual usable capacity is often less than advertised due to energy conversion losses. A good rule of thumb is to assume you’ll get about 60-70% of the stated capacity in real-world use. Also, keep in mind that larger capacities mean longer recharge times when you do find an outlet.
2. Weight and Size: The Backpacker's Dilemma
Every ounce counts when you’re carrying everything on your back. The lightest power banks weigh around 5-6 ounces (140-170 grams), while high-capacity models can push over a pound (450 grams). Think carefully about your trip duration and power needs – for a weekend trip, a lighter bank is usually sufficient, but for longer expeditions, the extra weight of a higher-capacity bank might be justified.
Consider the physical dimensions too. Slim, flat designs pack better than bulky units that waste valuable space in your backpack. Some of the best designs are barely thicker than a smartphone, making them easy to slip into various pockets rather than taking up main compartment space.
3. Durability and Weather Resistance
Your power bank will likely experience bumps, drops, and exposure to the elements. Look for models with shock-resistant construction and at least IPX4 water resistance (splash-proof). For more demanding conditions, IP67 or IP68 ratings provide dust and water immersion protection. Rubberized coatings can improve grip and provide some impact protection.
Military-grade drop test certifications (like MIL-STD-810G) indicate superior durability, though they often come with a weight and cost premium. For most backpackers, a well-built consumer-grade power bank with basic weather protection is sufficient, but if you’re heading into particularly rough terrain, investing in higher durability pays off.
4. Charging Speed and Technology
Fast charging can be a game-changer when you have limited time at rest stops or in camp. Look for Power Delivery (PD) or Quick Charge (QC) technology, which can charge devices significantly faster than standard charging. USB-C ports generally support faster charging than older USB-A ports.
Pay attention to both output (charging your devices) and input (recharging the power bank) speeds. Two-way fast charging means you can recharge the power bank quickly when you do find an outlet. Also, consider how many devices you need to charge simultaneously – multiple ports are great for group trips or if you carry multiple electronics.
5. Solar Charging: Useful Feature or Marketing Gimmick?
Solar panels on power banks sound ideal for backpacking, but the reality is more nuanced. Most integrated solar panels are relatively small and charge very slowly – we’re talking days to fully charge a power bank in ideal conditions. They’re best used as a trickle-charge supplement rather than a primary charging method.
That said, solar charging can be valuable for emergency situations or very long trips where you might not see an outlet for weeks. If you seriously need solar capability, consider separate foldable solar panels that have larger surface area and can charge your power bank much faster than integrated panels.
6. Additional Features Worth Considering
Some power banks include useful extras like built-in flashlights (often with SOS modes), wireless charging, or digital displays showing remaining capacity. While these features add weight and cost, they can be valuable in specific situations.
Built-in cables are incredibly convenient since you can’t forget them, but they’re also potential failure points. Digital displays are more accurate than simple LED indicators for knowing exactly how much power remains. Wireless charging is nice for reducing cable clutter, though it’s typically slower than wired charging and requires careful placement to work reliably.
7. Safety and Certification
Never compromise on safety with lithium batteries. Look for certifications like CE, RoHS, and FCC that indicate the product meets basic safety standards. More importantly, ensure the power bank has protection against overcharging, short circuits, and overheating.
Reputable brands typically have better safety features and quality control. Avoid no-name brands with prices that seem too good to be true – poor-quality lithium batteries can be dangerous, especially when subjected to the temperature extremes and physical stress of backpacking.
Frequently Asked Questions
1. How many times can a 10,000mAh power bank charge my phone?
It depends on your phone’s battery capacity, but generally, a 10,000mAh power bank can charge a typical smartphone 2-3 times completely. However, due to energy conversion losses, you’ll typically get about 60-70% of the advertised capacity in actual use. So for a phone with a 3,000mAh battery, you might get 2 full charges plus some extra, rather than the theoretical 3.3 charges.
2. Are solar power banks worth it for backpacking?
Solar power banks can be useful but often don’t live up to the marketing hype. The small solar panels on most power banks charge very slowly – it might take several days of ideal sunlight to fully charge the battery. They’re best as an emergency backup or for trickle charging rather than your primary power source. If you truly need solar capability, consider separate foldable solar panels with higher wattage that can charge your power bank much faster.
3. How should I pack my power bank while backpacking?
Keep your power bank in a protected, easily accessible part of your pack. Avoid storing it in outside pockets where it could fall out or be exposed to direct sunlight for extended periods. Extreme temperatures can damage lithium batteries, so don’t leave it in a hot car or freezing cold tent when not in use. Many backpackers keep theirs in a small dry bag or protective case to prevent scratches and minor impacts.
4. Can I bring a power bank on an airplane?
Yes, but with limitations. The FAA allows power banks in carry-on luggage only, not checked bags. There’s typically a limit of 100 watt-hours (about 27,000mAh at 3.7V) without special approval. Most standard power banks are well under this limit, but some high-capacity models like the 56,800mAh MaiVoz we reviewed cannot be carried on planes. Always check your airline’s specific regulations before flying.
5. How long do power banks typically last?
Most quality power banks will last for 300-500 charge cycles before their capacity significantly degrades. With typical use, that’s about 2-3 years of regular service. Proper care extends lifespan – avoid completely draining the battery, don’t expose it to extreme temperatures, and use the manufacturer’s recommended charging equipment. Higher-quality cells and better construction typically mean longer service life.
6. What's the difference between mAh and watt-hours?
mAh (milliamp hours) measures electrical charge, while watt-hours measures energy. Since power banks operate at different voltages, watt-hours gives a more accurate comparison of total energy capacity. To convert, multiply mAh by voltage (typically 3.7V for lithium batteries) and divide by 1000. For example, a 10,000mAh power bank at 3.7V has about 37 watt-hours. Airlines use watt-hours for their limits because it’s a more consistent measure across different battery types.
Final Verdict
After testing these power banks on actual trails and in various conditions, I’m convinced that the right battery pack can make or break your backpacking experience. While personal needs vary based on trip length, group size, and electronic dependencies, the Anker PowerCore 10K stands out as the best overall choice for most backpackers thanks to its perfect balance of reliability, weight, and performance. For those on a tighter budget, the VEEKTOMX offers impressive capability at an accessible price point, while the ELECOM NESTOUT provides bombproof durability for the most demanding environments.
Remember that the lightest power bank is the one you leave at home, but the most frustrating trip is the one where your devices die when you need them most. Choose based on your specific needs, and don’t forget that no power bank replaces proper trip planning and conserving your devices’ battery life through settings adjustments and mindful use. Happy trails and may your batteries never die!
