Home Peripherals Mac or Windows notebook/USB charger (review)

This multi-faceted, multi-tipped notebook/USB charger is just the answer to replace a lost or broken charger – with the added flexibility that it can run off 110/240V as well as a 12V car “lighter” port.

Replacement notebook chargers are expensive – a genuine Apple Mac 85W MagSafe 2 will set you back around A$129 and a genuine HP a similar amount. But Laser has one for all – a 90W notebook charger PW-90MACDC with 1.5A USB charging port and 12 interchangeable, voltage sensing tips, plus 240V or 12V DC connection for A$79.95.

I needed a spare charger to suit a range of test bed devices, and this is it! The tips support Toshiba, NEC, IBM, Lenovo, Sony, Fujitsu, Samsung, HP, Acer, ASUS, Dell, Apple and many more and will deliver the manufacturers rated voltage and current – from 15 to 20V.

An LCD screen shows the charging voltage, and Watts and it is current, voltage, temperature and short circuit overload protected so it cannot harm your notebook or device.

Apple aficionados will delight at the 16.5 and 18.5V Magnetic “MagSafe” tips, and it even has an obscure 20V, 3-hole tip used in the past by Dell.

I tested it across a wide range of older notebooks it precisely delivered the power needed.

The USB Port will deliver 1.5A – a little below the 2A for high drain devices but it managed to keep up with everything from the latest smartphone to tablets.

Note you can check if a 90W charger will handle your device using Ohm's law – Volts x Amps = Watts. For example, if you have a 19V device and it requires 3A then it is 19 x 3 = 57W. Most devices require under 90W.

At the price and the obvious quality, it’s a great investment as a replacement or spare charger.
