BiXPower LC90B 7.4mm Right Angle Power Connector Adapter
for Dell & HP/Compaq Laptops
The BiXPower LC90B is a compact 90-degree
right-angle power connector adapter designed for compatible
Dell and HP/Compaq laptop power adapters using
the older large 7.4mm center-pin DC connector.
It converts a conventional straight laptop power connector into
a convenient right-angle connection. This can
reduce the amount of space required beside the laptop and allows
the power cable to route more naturally along the side of the
computer.

Turn a Straight Laptop Power Plug Into a Right-Angle Connection
Many laptop AC adapters use a straight DC connector that extends
outward from the side or rear of the computer. In locations with
limited clearance, the straight connector and cable can occupy
unnecessary space.
The LC90B changes the direction of the connection by approximately
90 degrees, allowing the cable to run closer to
the laptop instead of extending straight outward.
Compare without and with he Right-Angle Adapter
The right-angle configuration is particularly convenient when
using a laptop close to a wall, on a small desk, in a vehicle,
or anywhere you want to reduce the amount of space occupied by
the power connection.
Designed for the Large 7.4mm Dell / HP Connector
Important Compatibility Notice:
This adapter is designed for the older
large 7.4mm Dell and HP/Compaq power connector with
a center pin.
It is NOT compatible with the newer smaller 4.5mm
Dell/HP connector.
Please check your existing power connector before ordering.
Connector Configuration
The LC90B has a female connector on one side and a male connector
on the other, allowing it to fit between a compatible laptop power
adapter and the laptop.
Female Side — Connects to Your Existing Power Adapter
The female side accepts the compatible
large 7.4mm Dell or HP/Compaq male power plug
from your existing AC adapter or other compatible power source.
Male Side — Connects to the Laptop
The male side uses the large Dell/HP-style connector with an
approximately 7.4mm outside diameter and 5.08mm inside
diameter with center pin.

Before Ordering:
Compare your existing connector with the photos on this page.
The outside diameter should be approximately
7.4mm and the connector must be the
large center-pin style.
Model compatibility alone should not replace checking the
physical connector because manufacturers may use different
connector types within a product family.

Simple, Compact Solution for Better Cable Routing
If your compatible Dell or HP/Compaq laptop uses the older
large 7.4mm center-pin power connector, the
BiXPower LC90B provides a simple way to change a straight power
connection into a compact 90-degree connection.
Its small size makes it easy to keep with your laptop charger,
while the right-angle design can improve cable routing and reduce
the space occupied by a straight plug beside the computer.
