75W Car 12V DC to 220V AC Power Inverter with USB Power Port

Pros: I bought this charger to charge my laptop in the car. I waited a long time to get it to be sent.
Looking at the external quality of it, I consider a very good product. The packaging is also of good quality and is reliable.

Cons: When I tried to use, before connecting any equipment on it, I checked the output voltage with a multimeter and had a high voltage. (Output voltage 252 V). All my machines works let that 240 V, then if I would link some equipment it could burn.

Other: I think I've had bad luck. The equipment looks good, but I did not come good.

Pros: Sturdy design.
Has a high current protection.

Cons: Cannot provide 75W. Actually, it cannot provide 65W, either. This is what my notebook needs. When the battery is full, I can use it. But if the battery is drained, I have to wait for the battery to be charged fully before powering it up. Otherwise, the power led starts blinking and the electricity comes and goes. This is good as it's a proof that this inverter has high current protection!
The USB port stopped working after some time, I cannot figure out the reason why... I cannot charge my BB device any longer. But hey, I have a solution: plugging in the wall charger to the inverter!
