LC-Power LC-NB-PRO-90-C — 90W USB-C Notebook Power Supply
90W USB-C PD5–20V up to 4.5A1.2m USB-C cableUniversal 110–240V
The LC-Power LC-NB-PRO-90-C is a 90W universal notebook power supply with a fixed USB-C cable, built for laptops, tablets and phones that charge over USB Power Delivery and need more headroom than a basic 65W charger.
It negotiates the standard PD voltages from 5V to 20V and delivers up to 4.5A at 20V, so a 90W-class USB-C laptop gets close to its full rated charging power while smaller devices simply draw what they need. It is a practical spare for the office, a second charger for home, or a replacement when the original adapter is lost.
Before you order: Your laptop must charge through USB-C Power Delivery. Laptops with a round barrel or proprietary tip (older Dell, HP, Lenovo slim-tip, etc.) cannot use this adapter. If your laptop ships with a charger above 90W (e.g. 100W, 130W or 140W), it will still charge from this unit, but more slowly and possibly not at all under heavy load.
What's in the Box
- 1x LC-NB-PRO-90-C power supply unit with fixed USB-C cable (approx. 120 cm)
- 1x mains power cable (approx. 150 cm)
What It Means in Practice
- One adapter can charge a USB-C laptop, a USB-C tablet and a USB-C phone — whatever device is plugged in, the adapter supplies the voltage it requests.
- The USB-C cable is permanently attached, so there is no separate cable to forget, but it cannot be swapped for a longer one.
- At 20V/4.5A it covers most 13–15" business ultrabooks and many 90W-class workstations designed for USB-C charging.
- The brick sits on the floor or desk with a detachable mains lead, which gives about 2.7 m total reach from wall to laptop.
What Will Not Work
- Laptops with barrel-type or proprietary charging connectors — there are no adapter tips in the box.
- 28V/140W Extended Power Range charging (e.g. 16" MacBook Pro fast charging) — this unit tops out at 20V/90W.
- Charging two devices at once — there is a single USB-C output.
- USB-A devices without a USB-C cable — the output is USB-C only.

Frequently Asked Questions
Will it charge my laptop that came with a 65W USB-C charger?
Yes. The laptop requests the power it needs and this adapter can supply up to 90W, so a 65W laptop simply draws 65W or less.
My laptop came with a 100W adapter. Can I use this?
Usually yes, but charging is slower and under heavy load (gaming, rendering) the battery may still drain. Tell us your laptop model and we will confirm.
Can I charge my phone with it?
Yes, if the phone charges via USB-C. The adapter falls back to the 5V or 9V profile the phone requests.
Does it work with a USB-C docking station?
Only if the dock accepts USB-C PD input up to 90W; many docks need their own dedicated barrel or higher-power supply.
Singular Expert Insight · Buyer's Guide
The LC-NB-PRO-90-C is the sensible middle ground between compact 65W travel chargers and bulky 130W+ workstation bricks: enough power for nearly every USB-C business laptop, with a full protection set. Before ordering, check that your laptop charges through USB-C and what wattage its original adapter is rated at. Browse our
laptop power supplies if you need a barrel-tip or higher-wattage model.
✓ Buy it if your laptop charges over USB-C and its original adapter is 90W or less, and you want a spare for office or home.
✕ Skip it if your laptop uses a barrel or slim-tip connector, or needs 100W+ / 140W EPR charging.
→ Also consider LC-Power LC-NB-PRO-140-C if you need 140W with 28V EPR, or LC-NB-GAN-45-C for a compact 45W unit.
