TogglePower banks are an absolute game changer when it comes to keeping your devices alive. It ensures that you never run out of juice. As a digital nomad, it’s a blessing to keep your devices powered up while traveling and working.
In this article, I’ve curated a list of the 6 best portable power banks for digital nomads. Whether you need something lightweight, with a power bank with outlet capabilities, or one with rapid charging, we’ve got you covered. Each power bank comes with specifications, pros and cons to help you decide.
But before jumping to the list, let’s check out the criteria we should keep in mind while choosing the best portable power bank.
How to Choose the Best Portable Power Bank for Travel?
These are some essential factors you should consider while choosing the best portable power bank:
1. Capacity (mAh): It indicates how much charge a power bank can hold. So, higher the capacity, the more times you can charge your devices. For short trips, a 10,000mAh power bank might suffice. But for longer trips or charging multiple devices, 20,000mAh to 25,000mAh power banks are recommended.
However, be aware of airline restrictions on power bank capacity. Often, airlines put limits on the capacity. Besides, it is instructed to be carried in carry-on luggage.
2. Charging Speed or Output Power (W): A portable charger with a higher wattage can charge larger devices like laptops or multiple devices at once. Technologies like Quick Charge (QC) and Power Delivery (PD) offer faster charging speeds.
3. Output Ports and Compatibility: Ensure that the portable power banks have sufficient number of ports. The more ports, the more you can charge your devices at once. Also, don’t forget to check out the types of ports, like USB-C and USB-A.
However, your devices and the ports might not be compatible sometimes. So, check out beforehand whether the power bank supports your devices (most of the times, it works!)
4. Size and Weight: Travelers often tend to travel lightly. You don’t want to overpack yourself with heavy, bulky power banks and carry unnecessary weight. So, go for a light and portable but powerful power bank portable charger.
5. Durability & Build Quality: A sturdy and well-built power bank can resist the stresses of travel. Consider power banks with durable casings.
6. Price: The best power banks often come at a higher price, but they offer better performance and durability. I would suggest you to invest in a good one, as it will be a must-use piece of gear for your travel life.
Now that you know what to look for, let’s dive into our Top 6 Picks for Portable Power Banks.
