Review on BESTEK Inverter Converter Adapter Thinner by Jairo Cunha

I liked it at first. I liked the size, color and good length of the cord. I will say my testing wasn't very thorough HOWEVER I had problems using it with my laptop. It charged the computer perfectly when it was off, but when the computer was open the computer went from charging to not charging about every 20-30 seconds. Aside from the annoying changes in my computer (a little "ringing" and a change in brightness) I wasn't sure if it was harmful to the computer. I ended up sending it back and got the 300w version from the same brand. 150w is about half the size of 300w and other differences are that 150w has no AC switch and one outlet while 300w has 2. I prefer the size of this item but have opted for larger assuming it will last long enough if I have kids who need to charge multiple devices.
