Hello all,
I would like to suggest that the original review (Post #1) make some mention of the VC4's common inability to provide 1A to two cells at a time regardless of the power supply used.
HKJ does an excellent job with his reviews; I appreciate, trust and use them any time I'm thinking about a charger or battery purchase.
I purchased a VC4 after reading the initial review, with the bottom line that this is a good charger. I have only ever used the cable it came with. It didn't take long for me to discover that an Apple iPad wall wart wasn't enough to provide full charging ability to the charger, so I bought an even higher-powered wall wart. It, too, is frequently unable to allow 2 18650s in Channels 1 & 4 to charge at 1A, despite having plenty of power on paper.
So I did what I should have done in the first place and read deeper into this thread, where I see that I am not alone in this. I fully admit that had I read further than the initial post -the proper review- that I would have seen the problems, but I didn't and perhaps other potential purchasers won't either; the reason that I read only HKJ's post was that I trust him totally and thought that any problems would be explained in the review.
Please understand that I'm not faulting HKJ or his review in any way, but rather trying to help it in its purpose of informing potential buyers about the product before they make a purchase.
As always, thank you HKJ, for all the work you do for the community!
