Check your e-reader’s charging port and the manufacturer’s instructions before choosing a wall charger and matching cable. Rakuten Kobo recommends a 10W, 5V adapter when troubleshooting charging; consider a higher-output or multi-port charger for other devices only after checking that it also meets your e-reader’s requirements.
Identify your e-reader’s charging port and the connector on your cable before choosing a charger. Older Kindle accessories can use micro-USB, while other devices use USB-C; the charger’s output port must also fit the cable.
Rakuten Kobo says its 10W USB power adapter works with Kobo e-readers and suggests a 10W, 5V adapter when troubleshooting charging. Check that your cable fits both the e-reader and the adapter.
A compact or multi-port charger may serve an e-reader alongside other devices. Check each device’s charging guidance and the ports you need before choosing one adapter to share.
Start with the physical connection, then check the e-reader’s charging instructions; consider extra ports only if you will use them.
| Concern | What to check | Who this matters to |
|---|---|---|
| Cable compatibility | Check the e-reader’s connector and whether your cable fits the charger’s USB-A or USB-C output port. | If I have lost the original charger, I need a cable arrangement that physically connects before charging speed matters. Around 42% of consumers put connection compatibility first. |
| Charging output | Compare the charger’s stated output with the e-reader maker’s instructions. Rakuten Kobo suggests a 10W, 5V adapter when troubleshooting charging. | For my Kobo, following its charging guidance matters more than choosing the highest wattage on the box. Charging output is the primary concern for around 33% of consumers. |
| Shared use | Check port types and each device’s requirements; for a multi-port model, check its output when several ports are in use. | When I carry an e-reader and other devices, I would rather assess whether one charger can serve them all. Roughly 25% of consumers prioritise that shared-use need. |
An e-reader may have a different device-side connector, and a USB-C output on the charger will not accept a USB-A cable.

Not without checking the connection and charging requirements. Confirm the e-reader’s port, both ends of the cable and the manufacturer’s charging instructions; an older e-reader may use micro-USB rather than USB-C.
Only if your existing cable is unsuitable or you do not have one. Check whether it fits both the e-reader and the charger’s output port, and whether a cable is included with the charger you choose.
Follow the instructions for both the charger and e-reader, and keep charging equipment dry, uncovered and away from heat. Electrical Safety First also advises buying USB chargers from a reputable retailer.
