Buying Guide for the Best Power Bank For Backpacking
Picking the right power bank for backpacking is essential to ensure your devices stay charged while you're off the grid. The best choice will depend on how long you're away from electricity, the number of devices you need to charge, and how much weight you want to carry. It's important to balance capacity, portability, and features so you aren't weighed down but still have enough power for your journey.Battery Capacity (mAh)Battery capacity, measured in milliamp hours (mAh), tells you how much charge the power bank can store. Higher capacity means more charges for your devices but often results in a heavier and bulkier unit. Small (up to 10,000mAh) are lightweight and suitable for short trips or topping up a phone. Medium (10,000–20,000mAh) can charge a phone multiple times and strike a balance between size and utility for a weekend. Large (over 20,000mAh) are best for longer trips or charging more than one device, but add significantly to your pack's weight. Consider how many devices you'll bring and how often you'll need to charge them to choose a capacity that matches your needs without unnecessary extra weight.
Weight and SizeWeight and size determine how easy it is to pack and carry your power bank. Backpackers need to minimize weight, so even differences of a few ounces can matter. Smaller, lighter power banks are easier to pack but store less energy, while larger ones may become burdensome. If your main goal is to travel light and you have access to charging opportunities, choose a compact model; for extended periods without access to outlets, you may need to accept a bit more bulk for the extra power.
Output Ports (Number and Type)The number and type of output ports set how many devices you can charge at the same time and which devices are supported. Some power banks offer just one port, which is fine if you only need to charge a phone, while others have multiple or varied ports like USB-A, USB-C, or even AC outlets for charging multiple devices such as phones, tablets, cameras, or GPS units. Think about your gear—if you have only one essential device, a single port is enough; if you need to charge multiple gadgets regularly, look for models with more and the right type of ports.
Charging Speed (Output Power)Charging speed, typically measured in watts (W) or amps (A), indicates how quickly your devices will charge. Some devices, like modern phones or tablets, support fast charging and will benefit from higher output (e.g., 12W, 18W, or more), while others charge slowly by design. Lower speed (around 5W) is fine for overnight or less urgent charging, while higher output is useful for quick top-ups on the go. Match the output power to the requirements of your devices for the best experience during your trip.
Recharging Method and TimeRecharging method refers to how you replenish the power bank itself: most use USB, but some support solar panels or wall outlets. Recharging time can range from a few hours to overnight, depending on capacity and method. If you'll have chances to recharge during your trip, a model with a quick recharge might be ideal; if you're off-grid the entire time, consider options with solar compatibility, but bear in mind solar is much slower and weather-dependent.
Durability and Weather ResistanceBackpacking exposes gear to bumps, moisture, and dirt, so durability and water resistance are important. Some power banks are built with rugged, shockproof casings and rated for splash- or rain-resistance. If you're going on casual or indoor trips, basic models suffice; for wilderness or uncertain weather, look for higher durability and at least some water resistance to protect your investment.
