I do worry that this device may be imitation. However it does exactly what I require it to, charges my laptop. I try to not leave it in for excessive periods. But on the occasions that it has been the device has not felt like it is overheating.
This is great. I can now charge up the laptop :-) The cable is a little short so I would suggest that if this needs to stretch from the plug socket maybe look for a longer cabled one. For me though this is perfect!
My cat chewed through my original laptop charger and was desperate to replace it, i ordered on amazon and received next day, my kids were so happy they could now use the laptop, good buy for the price😄
