Why Choose the Anker Nano 45W?

Compact 45W smart display charger packed with mobile travel devices — At 75g, the 45W model is the easier everyday-carry choice. Its smart display can show charging power, temperature, status, and supported device information.

The Nano 45W is designed for people who want a charger small enough to keep in a pocket or compact travel pouch. Its screen does not make charging faster, but it gives useful confirmation that a device is connected and receiving power. The single-port design is simple, though it cannot charge two devices at once.

Much smaller and lighter
Useful real-time charging display
Excellent for phones and tablets
Foldable travel-friendly design

45W limitations

Not ideal for high-performance laptops
Only one USB-C port
No charging cable included
Display recognition is optimized for newer USB-C iPhones

Why Choose the Anker 317 100W?

100W USB-C charger powering a large laptop at a home office desk — The 100W model is the practical choice when a laptop needs substantially more power than a phone or tablet.

The Anker 317 focuses on output rather than smart features. Its 100W maximum makes it a better match for larger USB-C laptops, while the included 5-foot E-Marker USB-C cable adds useful value. It is still a single-port charger, so the full 100W is dedicated to one connected device.

100W strengths

More suitable for demanding USB-C laptops
100W PowerIQ 3.0 and PPS output
5-foot 100W USB-C cable included
Foldable US plug and broad compatibility

100W limitations

Larger and heavier than the 45W model
No smart display
Only one USB-C port
Extra power may be unnecessary for phone-only charging

Which One Is Right for You?

45W charger with phone and tablet compared with 100W charger beside a laptop — Choose based on your largest device: the 45W model favors portability, while the 100W model favors laptop performance.

Buy the 45W model if you mostly charge a USB-C phone, tablet, handheld device, or a light laptop and want the smallest possible charger with visible charging feedback.

Buy the 100W model if a USB-C laptop is your main device, you want considerably more power, or you need a capable 100W cable included in the box.
