In the era of remote jobs, digital nomadism, and streaming services becoming more and more widespread, it is no longer just the convenience to be able to always stay powered, but a necessity. If you want to travel, you can use a power bank or a charger, in case you want to visit a cafe, or just need to power through a power outage at home.
Ultra-slim wireless power banks, high-wattage GaN laptop chargers, and other portable power devices are smarter, faster, and more compact than ever before, and 2025 has seen the rollout of a new generation. This guide takes you through all you ought to know- what to purchase, how to select it, and what to avoid.
All power banks (or chargers) are not the same thing. The right one should be chosen based on how you charge, where it is charged, and what it is charged.
These portable, easy-to-carry units are usually the 5,000 to 10,000 mAh variety and make a perfect match to charge up your phone daily. They are exactly what is required to charge smartphones or a pair of earphones, or a smart watch, at least twice a day. USB-A and USB-C ports plus an LED screen make this type of model even more functional with no additional bulkiness. Most of them are TSA-friendly and pocket-sized, making them an essential travel item.
Specifically targeted at newer smartphones, chargers magnetically snap in the back of a phone compatible with them. Normally, they transmit 7.5W to 15W of wireless power, that is, without cable connections. Though they are slower and best suited to people who use it, these types of internet are easy to carry around and quite simple yet very appropriate to commuters and minimal travelers.

In order to be able to charge a MacBook or other USB-C driven laptop on the road, power banks with a capacity between 20,000 and 30,000 mAh and a power delivery of up to 140 W are necessary. These types of units usually have several ports and are powered by Power Delivery (PD) 3.0 or 3.1. They can charge a laptop to charge 50-60 percent within less than one hour, which is most suitable for a remote worker or students.
It is the new Gallium Nitride (GaN) charger that is changing the charging game. They are cooler, have higher power, and are physically smaller than traditional silicon components since they replace them. Numerous new chargers also have a 65W, 100W or even 140W output power-big enough to charge full-sized laptops. Multi-port GaN hubs can also contribute to less clutter on the desktop: those can go in one slender device that not only charges the phone, but also the tablet and the laptop.

Batteries with more than 100 watt hours (approximately 27,000 mAH) are typically not permitted in carry-on bags unless it has been approved by the airline. This is because you are not supposed to bring a battery whose size is not displayed on the label in watt-hours or mAh to cause problems at the airport.
Individual gadgets require different power demands. Fast charging on a smartphone typically takes only 18 W to 30 W, whereas a 13-inch laptop can take 67 W. Bigger laptops, such as the 16-inch MacBook Pro, require between 96W and 140W to perform to the best of their abilities. Significantly, selecting a charger that allows you to control its output, or one that smartly detects, will make sure that your gadgets are nourished and adequately charged without heating up or getting underpowered.
It is also recommended to have at least one USB-C PD port to ensure faster charging and increased support. Other USB-A ports are wonderful with old devices. There are also more advanced chargers with AC outlets or even HDMI, just to allow more performance.

Advanced battery technology enjoys partial charging. Do not use up to 0% regularly and never keep them at 100%. To maintain it under long-term conditions, charge it to approximately 50 percent and place it somewhere cool and dry.
In case you are using high-wattage chargers, use cables of the same rating as well; a 60W cable on a 140W charger will increase the charge cycle time or even stop it altogether. When you can, use cables that say PD 3.0 or 3.1 on them.
