Average Reviews:
(More customer reviews)I purchased this product with the intention of using it for charging my laptop while on the road. According to the product's spec sheet, it is rated to supply 140-watts of continuous power (and 150-watts peak) and it is marketed as being a suitable power supply for laptops. Unfortunately, when I plugged my laptop (which uses a 90-watt charger) in to the unit it would overload and trip the surge protection after a few seconds. I was thoroughly unamused.
Additionally, I found this nugget from a review on Newegg:
"The problem with this unit is that neither the hot or the neutral plug on the unit are referenced to ground. In other words, the neutral actually has a potential of 60v above ground. This can lead to some shocking situations. The ground leg of the inverter is just a dummy hole -- there is no actual ground.
In layman's terms, the electrical design of this unit is very poor and would never achieve household electrical standards. I can't figure out how they are allowed to manufacture and sell this unit especially when they advertise it for use with laptops."
And upon further inspection, I can confirm that this is accurate, which could possibly be the reason why my laptop charger overloads the unit despite the fact that the unit is supposed to be able to supply 140-watts continuously.
This unit does seem to work well for small electronic devices, but I cannot recommend this unit for any electrical device that draws much power or uses a 3-prong connector.
