What's Hot: Can charge three devices simultaneously, small and easy to carry, comes with tips for almost all PC notebooks.

What's Not: No built-in battery.

Kensington makes many power solutions for mobile phones, tablets and notebook, and they have released a charger that can charge all three simultaneously. The Kensington AbsolutePower charger provides 100 watts of power to charge your laptop, tablet and phone all at once. It comes with a laptop charging port and cord, a full USB charging port and a microUSB charging port for phones. That's not all, the Kensington AbsolutePower charger comes with 10 smart tips to charge laptops from major brands and a USB/microUSB cable for charging the iPhone 4S.


The Kensington AbsolutePower Laptop, Phone and Tablet Charger comes in a relatively small package. At 4.3 x 2.75 x 0.73 inches, the Kensington AbsolutePower charger is wider than most notebook chargers but thinner than many. The charger weighs 10.6 ounces with charging cables included. The charger has a textured surface so it's not too slippery to handle, and the input charging cable is detachable. The charger is designed for you to easily carry it in your backpack or computer bag.

The Kensington AbsolutePower charger has a power input port on one side and three output ports on the other. The laptop output port is built into the charger with a non-detachable cable. The charge comes with a bag of notebook charging tips that should fit notebooks by all major brands sold in the US including HP, Dell, Toshiba, Lenovo, Sony, Asus, Samsung and more. Kensington provides a cheat sheet for you to find the right tips for your notebook. Next to the notebook output cable, you will find a microUSB port to charge any phone with that port, or via USB (like an iPhone) using the included USB/microUSB adapter. Finally there is a full USB charging port for your tablet to charge via the charger. There is also a small switch that you can flip with a pen or paper clip to switch between 16V and 19V power depending on your notebook's requirement.


The Kensington AbsolutePower charger outputs plenty of power in watts and amps for small and large devices. The charger guarantees 90W (100 watts peak) output power while charging three devices. The charger is also a world charger (may require prongs adapter) with 100V-240V input. We tested the AbsolutePower charger with the HP Envy 17" laptop, the Asus ZenBook UX31, a couple of Lenovo laptops as well as the iPad 2, a couple of Android tablets, and the iPhone 4S and several Android phones. The charger powered everything nicely. We were able to find the right tips for all notebooks we tested from the included tip bag.

Here are the detailed input and output numbers for the Kensington AbsolutePower charger so you can match your devices' power specs:

Input: 100-240VAC, 50-60Hz, 1.5A max
Output Voltage: 14-17VDC at 5.0A max; 17-21VDC at 4.72A max
Output Power: 90W continuous, 100W peak (minimum 5 minutes), 5V 2.0Apms total USB output.

The Kensington AbsolutePower charger for laptop, tablet and phone has built-in smart power technology that automatically sense the correct amount of power to charge your devices. It has over current protection, over voltage protection as well as protection against short circuit and over heating.


If you take several devices on the road with you and often find limited power outlets, especially at airports, the Kensington AbsolutePower charger is a great choice to take with you and charge your notebook, tablet and phone all together using one AC outlet. The charger has more than adequate power output for most laptops and certainly tablets and phones to charge simultaneously. The included laptop charging tips are very handy if you change your laptops often, and the charger is small and light to carry. The only thing we found ourselves wishing to have in addition is a built-in battery that can save you in a pinch even if it might add a couple of inches of thickness and a bit more weight.
