Can a Power Bank Be Charged by a Laptop and Other Portable Charging Solutions

Are you interested in learning more about the intricacies of charging devices on the go? Specifically, can a power bank be charged by a laptop? This article will explore the feasibility of this scenario while also delving into other innovative solutions for portable charging.

Power Bank Charging by Laptop: Possibilities and Limitations

Can a Power Bank Be Charged by a Laptop?

Yes, many power banks are designed to be charged via a laptop, though certain conditions must be met. Power banks typically output USB power at 5V, while laptop chargers usually have a different output voltage and wattage. A modern laptop charger tends to be around 19V at 3A. However, the key factor is not the power bank's capacity but its output wattage.

For newer laptops with USB-C ports that support Power Delivery (PD), you can charge a power bank using a compatible USB-C power bank with the PD designation. Older laptops without USB-C ports might require an adapter to charge through a regular USB port. It's important to ensure that both the laptop and the power bank have the necessary components for a successful charge.

Risks and Considerations

Charging a power bank with a laptop charger is mostly safe, but it may not be the most efficient way. Some power banks are designed for higher wattage, which is necessary for charging most laptops. For instance, a 10 kWh power bank is typically not sufficient for charging a typical laptop, which typically requires around 25W input. Even low-power laptops, like a budget Chromebook, generally need at least 25W to recharge. While it won't damage the power bank or laptop, attempting to charge a laptop with a severely underpowered power bank may result in slow charging or no charging at all.

There are some high-capacity power banks, such as those with AC plugs or those that support Power Delivery, which can charge a typical consumer laptop. These usually have higher capacities and are more costly. Brands like Eloop Orsen E45 power banks, which can charge with 20V at 2.25A (45W), are excellent for this purpose.

3 Different Ways to Charge a Laptop Without a Charger

1. How to Charge a Laptop with USB-C

If your laptop has a built-in USB-C port, you can charge your laptop via a USB-C cable. You simply need a compatible cable that has the necessary adapter, which can plug into an outlet. Some laptops even use a USB-C cable as their primary charger.

Plug one end of the USB-C cord into an outlet. Plug the other end of the USB-C cord into your laptop.

This method is straightforward and easy, provided you have access to a USB-C cord. However, in most cases, finding a compatible USB-C cable might not be as easy as ordering a new laptop charger. To avoid such situations, consider choosing a laptop with at least one USB-C port if you frequently travel. With the increasing popularity of USB-C, it’s safe to assume that most laptops will come with USB-C ports in the future.

2. Charging Your Laptop in a Car

A car is a great place to charge your laptop, especially when you're on the road. You need two things: an AC adapter with a USB Type A connector on one end and a USB-C connector on the other, and a USB car charger. This adapter enables you to charge your laptop using the car's electricity.

Turn on your engine. Plug the car charger into your vehicle's charging port (or directly into a USB port if available). Plug the USB-C connector into your laptop.

This method is particularly useful when you're on a road trip or need to quickly charge your laptop during a long car journey.

Conclusion

Charging your devices seamlessly on the go has never been more important, especially when you’re traveling. Whether you’re using a power bank, charging your laptop with USB-C cables, or utilizing car charging solutions, having a plan in place can make a significant difference. By understanding the specific requirements and limitations, you can ensure a smooth charging experience, no matter where you are.
