I have mixed feelings on this item. Does it work? Yes. No doubt about that. It just feels cheap and makes me question if the readouts are accurate or not. You ever just buy something and think “well it works, but does it really do what all it's supposed to do? Eh..” That's how I feel about it. I haven't even used all the charger plugs / outlets. I only needed it to charge 2 cigarette lighter outlet items and this was cheaper than a 2 plug in outlet. I would more thoroughly test this item and try to max it out, but I strongly feel like I would fry it. Just my opinion. It could work great, but I need the plug now so don't want to chance breaking it and dealing with headache of returning it.
