When traveling, whether it’s an international getaway, a cross-country road trip, or a cruise, staying connected is essential. From navigating with GPS to capturing memories on your phone or keeping in touch with loved ones, having a reliable power source is crucial. A portable power bank ensures your devices stay charged, no matter where your journey takes you. I always travel with a power bank that fits in my purse. Because I take SO many pictures on trips (and doing so drains the battery), I need to charge my phone on the go, so my trusty power bank allows me to keep snapping photos. And that makes me happy!
Why You Need a Power Bank
A power bank provides peace of mind. It allows you to:
- charge multiple devices, including tablets, e-readers, and even laptops.
- juice up your phone while using it to for GPS and/or taking pictures and videos.
- stay connected with family and friends.
- use apps without worrying about battery life.
- keep connected with travel providers such as hotels, car rental agencies, and airlines.
- keep your phone charged for emergencies.
Choosing the Right Power Bank
Not all power banks are created equal. Here’s what to consider:
Capacity (mAh)
Measured in milliampere-hours (mAh), this determines how much charge a power bank holds.
- 5,000–10,000 mAh: Ideal for charging a smartphone once or twice.
- 10,000–20,000 mAh: Great for multiple phone charges or charging a tablet.
- 20,000 mAh+: Can charge larger devices like laptops and multiple phones.
Power Output (W)
A power bank’s wattage (W) determines how fast it can charge your devices.
- 10W–15W: Standard charging speed for phones.
- 18W–30W: Fast charging for tablets and some laptops.
- 45W+: Required for most laptops and high-power devices.
Port Type & Number of Ports
Look for:
- USB-A (older but still common)
- USB-C (fast charging and used for modern devices)
- Multiple ports if you need to charge more than one device at a time.
Size & Weight
Consider portability. A 10,000 mAh power bank fits easily in a purse or pocket, while a 20,000 mAh+ model might be bulkier but is better for longer trips.
Best Practices for Using a Power Bank
- Charge it before you leave: Ensure your power bank is fully charged before traveling.
- Use the right cable: Match your device’s power needs with a compatible cable.
- Store in a safe place: Keep it in a carry-on bag for easy access.
- Avoid extreme temperatures: Heat and cold can affect battery life.
- Turn off unused devices: This conserves power while charging.
Charging Your Power Bank
- Overnight charging: Charge it while you sleep so it’s ready the next day.
- Use fast-charging options: If your power bank supports it, use a fast charger for quicker top-ups.
- Charge when you can: Plug it in whenever you have access to an outlet, like at hotels, cafés, or airports.
Accessories to Consider
- Multi-port USB charger: Allows you to charge your devices and power bank simultaneously.
- Short Charging Cables for Your Devices – A 1-ft cable is perfect for travel and avoids tangling.
- Universal Travel Adapter – If going abroad, make sure your wall charger works with international plugs.
- Protective Case: Helps prevent damage when carrying it in your bag.
- Portable Solar Charger – If you’ll be camping or off-grid, consider a solar-powered charger as a backup.
TSA Guidelines for Power Banks
When flying, you must carry your power bank in your carry-on luggage—they are not allowed in checked bags. The TSA restricts lithium-ion batteries based on capacity:
- Up to 100Wh (watt-hours): Allowed without airline approval (most power banks fall within this limit).
- 100Wh–160Wh: Requires airline approval.
- Above 160Wh: Not permitted on flights.
To calculate watt-hours, use this formula: (mAh × Voltage) / 1,000 = Wh (most power banks list this on the label).
