Portable Power Adapter
The eForChina adapter converts a 5.5 x 2.1mm female barrel connector to a USB-C male plug for notebook charging. Its compact form factor measures 53x15x13mm and weighs roughly 9g, making it easy to carry in a laptop bag. The housing uses PC plastic combined with metal contacts for a durable connection. This suits users who need to power older barrel-jack devices from modern USB-C sources.
Stable Connection Under Load
The metal contacts maintain consistent conductivity during extended charging sessions without overheating. The PC body resists deformation when the adapter remains plugged in for long periods. No active cooling is present, so the unit relies on passive heat dissipation through the housing. Continuous high-current draw is limited by the barrel connector specification rather than the adapter itself.
Simple Plug-and-Play Installation
Insert the barrel plug into the female socket and connect the USB-C end to the power source; no drivers or configuration are required. The snug fit prevents accidental disconnection during normal use. The only common issue is polarity mismatch if the source device uses a non-standard barrel wiring scheme. Verify the centre-positive requirement before connecting to avoid damage.

Questions about this item
How much heat or power loss does the 5.5 x 2.1 mm adapter introduce when running all day?
It is a passive connector with no active electronics, so it adds no measurable heat or power draw beyond the cable's own resistance.
What must I already own for the 5.5 x 2.1 mm female to USB-C male adapter to work?
You need a power source with a 5.5 x 2.1 mm barrel plug and a device that charges via USB-C and accepts the voltage that source provides.
Will the 53 x 15 x 13 mm adapter block adjacent ports on an older laptop when plugged in?
Its compact 53 x 15 x 13 mm body and light 9 g weight keep the profile low, reducing the chance of blocking neighbouring sockets on legacy machines.
