Can You Charge A Kindle With A Phone Charger?

Kindles have become widely popular for their ability to store thousands of books in one compact device. These fantastic travel companions, however, are not immune to power depletion. As a Kindle user, you’ve likely wondered, “Can I use a phone charger to charge my Kindle?” This article aims to provide a comprehensive answer to that thought, along with some useful tips for charging your Kindle more effectively.

The Connection Between Kindle and Phone Chargers

So, can you charge a Kindle with a phone charger? The simple answer is yes—you can. However, understanding why this is possible requires a brief foray into the technicalities of charging devices and the relationship between chargers and the devices they power.

Understanding USB Charging

USB, short for Universal Serial Bus, is a standardized technology designed to enable data transfer and power supply between devices. The USB technology incorporated into Kindle devices and phone chargers allows them to interchangeably provide a power source for each other.

Chargers typically consist of two main components: the adapter (the plug that goes into the power outlet) and the cable, usually featuring a USB Type-A connector on one end and a micro-USB or USB-C connector on the other, depending on the device being charged.

Kindle devices, for the most part, come with a micro-USB charging port. Therefore, any phone charger with the same micro-USB connector (or USB-C for the newer models) can be used to charge a Kindle.

Safety and Efficiency: Things to Consider

While you can charge a Kindle with a phone charger, there are a few considerations to ensure safety and maximize charging efficiency.

1. Power Output

Every charger’s power output, measured in watts (W), determines how fast it can charge a device. A higher wattage charger will generally charge a device faster. However, it’s essential to remember that the device (in this case, the Kindle) also plays a role in determining the charging speed.

Ensure your phone charger’s power output will not overload the Kindle’s battery. Most Kindle devices are designed to handle chargers with a power output of up to 5W. Using a charger with a significantly higher output could potentially heat up and damage the Kindle.

2. Quality of Charger

When using alternative chargers, always prioritize quality. Low-quality chargers pose a risk of providing unstable energy supply, leading to potential damage to your Kindle’s battery.

3. Plug-and-Cable Compatibility

Ensure the cable is securely and fully plugged into both the adapter and the device. Poor connections might cause erratic charging and potential device damage.

Charging Your Kindle Effectively

Beyond using a phone charger, here are more tips on charging your Kindle more effectively:

  1. Turn off Wi-Fi: Keeping your Kindle’s Wi-Fi off when not in use conserve battery life and allow for more efficient charging.
  2. Switch off the device: If you aren’t in a hurry to use your Kindle, switch it off while charging. This method allows the device to charge faster as it uses no power during the process.
  3. Regular charging: Frequent, routine charging can help to maintain the battery’s longevity. It’s generally beneficial to start recharging a device when the power falls to around 20%.


While you can charge your Kindle with a phone charger, it’s crucial to ensure that the amp output is suitable and that you’re using high-quality, reputable chargers. Applying the additional tips to your charging practices can further safeguard and extend the life of your Kindle device. Happy reading, and may your battery always be full when you need it most!
