In this guide, we’ve rounded up the best power banks and portable chargers for travel in 2025. From airline-friendly picks to solar-powered options and powerful laptop-compatible solutions, we’ll help you choose the right one so you’ll never have to stress about running out of battery again.
Before we dive in, keep these key factors in mind:
Capacity (mAh): This is the battery size, often referred to as mAh in specs. 10000mAh is the sweet spot for 2–3 phone charges and is almost universally allowed on planes. Larger capacities are great for laptops but may exceed airline limits (check for 100Wh/27,000mAh max for carry-on, making the biggest power bank on plane you can take around 26,800mAh).
Portability: Size and weight matter when every ounce counts in your bag.
Output Speed: Look for Fast Charging, Power Delivery (PD), and Quick Charge (QC) support to juice up your devices quickly. Some offer a trickle charging mode for small devices.
Input Options: How you recharge the bank itself. USB-C is fastest. Some innovative models even have a built-in AC wall plug.
Built-in Cables: A huge travel convenience, eliminating the need to pack separate cords and a common solution if your iniu power bank not charging or other brand is having cable issues.

Trickle Charge Mode: Some banks, like certain Anker models, have a trickle mode for low-power devices (earbuds, smartwatches).
Preserve Charge: To prevent a power bank not charging, store it at ~50% charge and recharge fully every few months if unused.
Choosing the right portable charger for travel in 2025 depends on your personal needs and the devices you rely on:
No matter which option you pick, having a dependable power bank means less time stressing about your battery life and more time enjoying your trip.
