What can I say about the Zanflare C4 Smart Charger/Analyzer? I had mediocre hopes for the C4, assuming it wouldn't live up to the hype it was hyped about. But I am happy to say that so far it has exceeded all my expectations. I have many NiMh and LiIon batteries. MANY, over 300. I also have 5 different smart chargers and many more. So my perspective comes from comparing things I already have and things I use. My favorite smart charger/analyzer so far has been the Opus BT-C3400. So most of my views relate to that. Ease of use and customization of individual slot configurations is even better than the C3400. Also, like the C3400, you can set/reset the configuration of each individual slot on the fly with instant response. The only feature the C4 doesn't have, while the C3400 has an automatic REFRESH mode. Instead you either manually use a quick test (discharge/charge [measure mAh in one charge cycle]) or a normal test (charge/discharge/charge [measure mAh in one discharge cycle]) and just do it manually 3 times to get the same process. Opus works with the Discharge Refresh program. Sometimes this can be tedious, sometimes it's useful to check the value between each loop to see what results you're getting at each point. I've found that if I need to upgrade some old batteries or ones that haven't been used for a while if they've lost some of their capacity, I can use the C3400 upgrade and then 'set and forget'. until it's done. On the other hand, when I buy new batteries I find that if I use the C4 quick test manually I may not have to do a full 3 cycle test to break them in. When the capacity is within 10% of the battery capacity. , then I do the normal test, which shows the capacity in the form of "discharge" (in my opinion, more accurately), write down the information and move on to the next set of batteries. The C4's display uses white on a blue background, so it's a little less attractive than the C3400's LCD, but it's by no means difficult to read. The C4 actually has a "virtual" battery that is always visible for each slot, giving a nice and simple visual status without having to try to "read" anything and without having to cycle through "modes". . Although just like the C3400, you can switch modes to view voltage, charge rate in mA, mAh capacity, internal resistance, etc. But that visual battery that shows visual status is always there too, so you "visually" know how close he is. must be carried out in the discharged or charged state. Effect: I can look at him from across the room and just "know". The C4 appears to be well ventilated, as does the C3400. It's a few inches longer than the C3400 but doesn't really take up much more desk space as you'll still need some ventilation space anyway. I've used the device with major battery types (AAA, AA, 14500, 18650, 26650) and various current settings (even up to 1A*4 slots) and the device itself doesn't overheat or heat up. than any other charger I own. So the "physical" properties are very similar. The exception is probably in the slots themselves. Instead of a stepped slot design like the C3400, they opted to simply make the slot's diameter a "semi-circle" required for the greatest battery support. This causes smaller batteries (AA, AAA) to "wiggle" a bit when trying to insert them. In other words, it requires more effort. Not much more, but enough to understand that this is the case. The C3400's dual tier system favors AA batteries for the bottom tier as they *almost* fit snugly into that bottom tier. The wider batteries fit quite well in the 2nd (top) row. So in that respect the C4 isn't as good as the C3400. Also, the metal tabs are a little "bent" (read faintly) so you may need to bend them straight up from time to time to make proper contact with the battery's negative terminal. Not a big problem but something they should fix in the future. Rather than writing a novel, I'll just summarize here and maybe add comments in the future if needed: The Zanflare C4, which is very similar to the Opus BT-C3400, looks like a solid smart charger/analyzer and works well. Can there be improvements? May be. But nothing serious is required here. For now I'm perfectly happy with the Zanflare C4 and the fact that it's cheaper than my C3400 is just the icing on the cake.
