FYI, I ordered two of these from BIC and got obvious fakes. I don’t own the genuine ENB version, so can only compare to HKJ’s review. Here is a copy of my product review that probably won’t get posted on the site…
Buyer Beware! I received fakes!
Pros:
From HKJ’s review, the original should perform quite well. That’s why I decided to order two of these, so I could give them as (safe and reliable) gifts. Unfortunately, I received two fakes. Take a look at the most recent customer pictures posted. That’s what I got. Unfortunately, I had already placed my order before those pictures were posted.
Fake vs ENB
+ 2 inputs vs 1 input
= indicator lights on opposite side from cells vs indicator lights on same side as cells
= It has independent channels like the ENB.
= Build quality seems decent
Cons:
I received fake, generic power banks with no logo on the case. Physically and functionally they are different from the ENB.
Fake vs ENB
- charges at 0.65A vs 1.0A
- very stiff clip springs over coil springs vs normal springs
I charged some Panasonic cells, then checked their voltages after the lights indicated that charging was complete. One cell was at 4.19v while the other was still only at 3.98v. I had to replug it in to resume charging.
- Not good because you can never be quite sure that you’re fully charged and ready to go.
On 1A discharge, the batteries don’t discharge together. Instead it draws separately like the original ENB does at 0.5A. I checked the cells after a partial discharge at 1A to find one cell about 3.2V while the other was still around 3.9V.
- Not ideal because one cell is subjected to unnecessary higher draw (=heat) plus the one discharged cell might stay in this low charge state for a prolonged time if you don’t regularly recharge after every use.
Disclaimer: I don’t actually own this version of the original ENB power bank. I’m just basing my info off of HKJ’s review. I do own the 3 cell ENB though.
Summary: The fakes are clearly inferior to the original ENB. Buy at your own risk. These were supposed to be for average users (my sisters), but now I don’t feel confident giving them away.
If you are okay with these shortcomings or can be bothered to constantly check the status of your cells by ripping them out of the stiff springs every time, then go ahead and buy this. Otherwise look elsewhere for the real deal. I’m so disappointed. 
I hope this saves someone the frustration of trying to save a few bucks and ending up with fake crap. I should have learned by now…
