Introduction

We would like to thank Huntkey for supplying the review sample.

Huntkey Enterprise Group was founded in 1995 and they are specialized in the development, design and manufacturing mainly of power supplies. Their power supply products cover all market segments from home use to business environments where custom tailored designs are needed. Among others they also build computer cases, chargers, power supply converters and universal notebook adapters. In today's review we are going to fully evaluate their latest universal notebook adapter which uses a Marvel superhero-inspired name, X-MAN.

Huntkey used a special production process for the X-MAN, allowing its dimensions to shrink so its volume is reduced by 45% compared to normal power adapters and at the same time power output remains at high levels. Thanks to the special design the adapter's lifespan is increased as well. With only 1.7cm height and 268g weight the X-MAN is able to provide up to 90W power to almost every notebook of the market, thanks to the ten exchangeable power-tips it it is equipped with. Besides the main 19V rail the X-MAN also comes with a 5V USB power port which can deliver up to 2A, so it can easily charge a wide range of tablet PCs besides other common devices (mobile phones, digital cameras etc). To provide safe power even in unstable power grids the X-MAN is equipped with three protections commonly used in desktop PSUs: Over-Voltage Protection (OVP), Over-Current Protection (OCP) and Short-Circuit Protection (SCP). The supported notebooks according to Huntkey include (but are not restricted to): HP/Compaq, Acer/Gateway, Lenovo/Thinkpad, Toshiba, ASUS, SAMSUNG, Sony, Fujitsu and Dell.

All the above sound nice and we are pretty sure that most of you would fancy a smaller power brick for your notebook with enough power to handle even demanding mobile GPUs. Using our tests we will find out if Huntkey managed to provide good performance to X-MAN, besides good looks and compact footprint. After all, this adapter uses a superhero's name so it has to perform equally strong.

Specifications

Max power output is 90W and this is impressive considering the restricted dimensions of this adapter. Huntkey promises higher than 89% efficiency and on the following pages you will find out if this stands true. The max operating temperature is only 40°C, however most likely the adapter will be exposed to room temperatures.
The available protections are restricted to the basics only and in most of the cases they will suffice and effectively protect your notebook. Thanks to the ten exchangeable power-tips the X-MAN is compatible with all popular notebooks available on the market and finally its price looks decent for what it promises to offer.

The main rail can deliver up to 4.6A so it will be able to feed even energy demanding notebooks. The 5V rail that feeds the USB charging port delivers up to 2A, a sufficient power level that will be enough to charge even tablet PCs.

Packaging

The X-MAN comes in a plain plastic, transparent, box which doesn't offer much protection. On the front the adapter along with its power-tips are visible and a small badge informs that a tip for Dell notebooks is included. Also the small height (of 1.7cm) along with the USB charging port are highlighted.


On the one of two sides we are informed that the X-MAN was made in mainland China and more specific at Huntkey's Shenzhen factory. The other side includes a small table showing the suitable power-tips for every popular notebook brand.


The rear side offers some basic information about the input voltage range, the output Watts and the max power each of the two rails can output.
