Can You Charge A Kindle With A Phone Charger?

As technology continues to refine and innovate the way we read, Amazon’s Kindle has found its way to our screens and reading habits. However, this digital shift also comes with new considerations, such as maintaining your device’s battery life for unstoppable reading. “Can you charge a Kindle with a phone charger?” is a common question that springs up. In this comprehensive guide, I’ll walk you through the ins and outs of charging your Kindle using various methods, notably phone chargers.

What is a Kindle?

Before diving into the charging question let’s first clarify what a Kindle is for anyone who might be new to the concept. Kindle is Amazon’s e-reader brand, which allows users to browse, download, purchase, and read e-books, newspapers, magazines, and other digital media.

Kindles have distinguished themselves with features like e-ink screens that are easy on the eyes, and a battery life measured in weeks rather than hours. They also offer an impressive library of books available in the Kindle Store.

How to Charge a Kindle

Under normal circumstances, Kindle devices are charged using their Micro USB cable and the corresponding adapter, often connected to a power outlet. The charging process is similar to charging other mobile devices: you connect the Micro USB end of the cable to the Kindle and the other end, the USB side, to the power adapter, which is then plugged into a wall socket.

Can You Charge a Kindle with a Phone Charger?

The short answer is, it largely depends on the phone charger in question, but yes, you can often charge a Kindle with a phone charger.

Kindle devices typically come with a USB 2.0 (Type A) to Micro-B cable. This is a common type of USB cable found in many devices, including certain phone chargers. So, if your phone charger uses a cable with a Micro-B end, it can be used to charge a Kindle.

It’s also worth noting that Kindle devices have a charging voltage of 5V, which is standard for many phone chargers. Charging current varies per device, but Kindle Paperwhite, for instance, works within the 500mA to 1A range. Most phone chargers meet these specifications, making them compatible for charging Kindles.

However, it’s crucial to be aware of the potential risks involving charging one device with a charger designed for another. Using a charger with higher voltage or amperage than the Kindle can handle could potentially damage the battery or the device’s internal circuitry. Fortunately, most modern phone chargers are designed with universal charging standards, drastically reducing these risks.

USB Charging

If you don’t have your Kindle’s dedicated charger or a phone charger at hand, you can also use your computer’s USB port. Connect your Kindle device to your computer using the USB cable. This method is slower, given the lower energy output from standard computer USB ports, but it’s a handy solution if you’re on the go or in a pinch.

Power Banks

Power Banks utilize the same charging principles as phone chargers and can also be used to charge your Kindle device. Always ensure that the power bank’s output voltage and current specifications align with your Kindle’s requirements.

Final Word on Compatibility and Safety

While it’s generally safe to charge your Kindle with a phone charger, power bank, or computer USB port, it’s always crucial to check the compatible voltage and current requirements.

If you notice any unusual behavior from the device while charging (like overheating, for instance), it’s best to stop using the charger and try a different method.

It’s equally important to remember that while the flexibility to charge with a phone charger can be convenient, it’s always best to use the dedicated charger as the primary method, resorting to alternative options as a secondary choice when necessary.

Extending Your Kindle’s Battery Life

Once you’ve answered the charging question, it’s also beneficial to touch on extending your Kindle’s battery life:

  1. Switch off Wi-Fi/3G: Your Kindle uses more power to connect to the Internet. Unless necessary, turn it off.
  2. Reduced lighting: Particularly for backlit Kindle models, lowering the illumination extends battery life.
  3. Close unused reading activities: The Kindle often keeps processes running in the background. Regularly closing unused items can save battery life.
  4. Regular firmware updates: Kindle’s firmware upgrades usually include system optimizations that can improve battery efficiency.


The convenience of Amazon’s Kindle revolutionized the reading experience, fitting thousands of books into one lightweight device. When it comes to battery life and charging, flexibility and knowing your options is key. Charging your Kindle with a phone charger is generally okay, as long as the charger’s specs align with your Kindle’s. Understanding these charging methods and following best practices for battery preservation ensures your Kindle always has power when you need it – so you can continue to switch through the pages of your latest read without worry.
