Lenovo Charger Types Explained: Round Pin vs Rectangle vs USB-C
Share
Lenovo has used three main charger tips over the years. If you have a ThinkPad, IdeaPad or Yoga and need a new charger, the first job is to find out which tip your laptop uses. It takes 10 seconds.
The 3 Lenovo charger tips
| Tip | How it looks | Common laptops |
|---|---|---|
| Round pin (older) | Round barrel with a pin inside | Older ThinkPads like T420, T430, X230; many older IdeaPads |
| Rectangle (slim tip) | Flat yellow rectangle | ThinkPad T440 to T470, X240 to X270, E-series, many IdeaPads and Yogas |
| USB-C | Small oval port | Newer ThinkPads (T480 and later many), Yoga, Lenovo Chromebooks |
Some Lenovo laptops also use a small 4.0mm round pin (IdeaPad 320/330, Yoga 510/710). Check your old charger label for 20V and the tip size.
65W or 90W?
- Most ThinkPads and IdeaPads came with 45W or 65W.
- Laptops with a dedicated graphics card or bigger screens often came with 90W.
- A 90W charger with the same tip and 20V is safe on a 65W laptop. It may even charge a bit faster.
A typical case
Say you have a ThinkPad X250 and your office kept the charger when you left the job. Your laptop has the yellow rectangle port, so a 20V rectangle-tip charger fits. 65W is enough, 90W is fine too.

FAQ
My ThinkPad has both rectangle and USB-C ports. Which charger?
Either works. Use the one that suits you.
Can I use a Lenovo charger on a Dell or HP?
