Best Portable Laptop Chargers Windows Central 2021

Whether you have work to do, games to play, or want to stay connected on the go, it's essential to have an excellent portable laptop charger in your bag. With options for business trips, camping trips, or long train rides, we've identified the best batteries for every situation. The POWERADD USB-C PD Power Bank has proven to be the best all-around charger that balances price, portability, and support for multiple devices.

Best Overall: POWERADD USB-C PD Power Bank

If you're looking for a good charger at a reasonable price, then look no further than the POWERADD USB-C PD Power Bank. With a 26,800mAh battery, you'll get at least one full charge for your laptop, assuming the laptop isn't in use while charging. Alternatively, you can charge smaller devices like your smartphone up to eight times, or charge multiple smaller devices at once.

While you can charge the Poweradd USB-C PD Power Bank and your device at the same time (passthrough charging), this may be harmful to the charger's battery and is not advised.

It has overcharge protection, overload output protection, over-current, and over-voltage protection, and short-circuit protection to help keep you and your devices secure. If you do have an issue with your Poweradd USB-C PD Power Bank, the company is known to have responsive customer service.

Best Battery BEAST: ALLPOWERS Portable Solar Generator Power Station

This beast of a charger can not only keep your laptop going, but it can power just about any portable device you have on hand. This includes mobile devices, emergency equipment, and even small appliances! With 78,0000mAh, you'll practically never have to worry about running out of power. You can charge a standard laptop five times over, and a typical smartphone over 25 times.

The ALLPOWERS Portable Solar Generator Power Station can be recharged via an AC adapter or from compatible ALLPOWERS solar panels.

This charger is a fantastic choice if you plan to live off the grid for a little bit. However, if you just want a simple laptop charger, you might want to look elsewhere.
