Seems to be a critique without saying so.
Sorry, I am an electronic engineer so I get curious and just more interested in knowing more details than your average consumer. We sometimes act like little kids on Christmas. As if we get a box that has electronics in it, we can't wait to take it apart and figure out how it works.
Never heard of the discharge after charging.
Well I first heard about this from mjlorton (on youtube) with his 8 bay version. So every 24 hours it loses about 24mah of charge. Not normally a problem, but something that should be mentioned about you shouldn't use the bays for long term storage. Probably shouldn't do that anyway, but you know some will anyway.
If I ever find a need to charge C or D size batteries, I’ll let you know.
Oh well I still use AAAA, AAA, AA, C, and D NiMH cells for mice, digital pens, keyboards, flashlights, radios, recorders, and radio control devices. I do have two Sony 14500 for two mice, but all of my 18650 and 26650 are used for vaping. Say if the GyrFalcon has a connection problem with a C size battery, it might also have a problem with a 26650 too.
when I charge batteries, I don’t stand there watching the display.
Well I don't either (unless I have my test equipment connected up to it and testing it). But I do tend to keep them close by while I do something else and glace that way every once in awhile. As if something goes wrong, you can do something about it.
For vapers, best darn charger by a long shot.
Well if you say so. I wouldn't have a problem reading those tiny screens, but some vapers would. And better chargers like my Triton charger, you can dial in any current from 100ma to 5A in 100ma steps. And these better and more expensive chargers does something that even the GyrFalcon lacks. As it is believed that starting off charging lithium cells by slamming it with high current isn't such a good idea.
Like take my Triton for example. Samsung says their 25r cells can be safely charged at 4A. So I can dial in 4A. But I'll dial in 1A just like your GyrFalcon for example. Yours starts off slamming 1A into the cell right away. But mine starts out at 100ma and slowly works its way up to 1A. This is less harsh on the cells and they are suppose to last longer charged this way.
Another practice that is said to double the life of the cell is to only charge it up to 90% instead of 100% capacity. Sure you lose 10% of the capacity, but you gain twice the life. You can do that too with the Triton. Interesting enough, Evolv's build in charger (at least on their DNA200 boards) has a toggle to enable this too.
Now would I recommend a Triton charger? Naw... my two are over 15+ years old and the newer versions of it haven't changed much since then. And if you were going to spend that much money on a charger (about $125 plus you need like a 10A 12v supply), there are many nowadays in that price range that does everything that the Triton does, plus even lots more.
