I have several chargers, ranging from first few ones that I got when I joined this hobby: iCharger 106B hobby charger, the Pila IBC and the Powerex Maha C9000.
Then came the Nitecores, the Xtars and my first analyzing charger with 4 bays, the Opus BT-C3100 V2.0/2.1, 2.2.
Then the new kids on the block that can cater to long cells and high amperage/auto current charging like my Miboxer C4-12 and their other models, all the way to the C8.
I also have the SkyRC MC3000, which I regretted to this day due to its complexity to use relative to simplicity of my other analyzing charger/analyzers.
This Eizfan S4 is a breeze to use, has very clear color LCD screen that you just tap to choose what you want, whether you want to charge, choose current, discharge on the next cradle while doing other sorts of modes in a combination of different cell chemistry (lilo, lipo4, nimh), all simultaneously, just like the Opus but without the Large color LCD Touch Screen that the Opus lacks.
No more memorizing of procedures, etc. or making a list or cheat sheets like the SkyRC.
Of course its price is quite a bit on the high side at $119 (with code)…but I tell you, once you actually get to use this thing hands-on, you’ll wonder why they only came up with this design now.
It’s just like using your smart phone by tapping on the screen, but without connecting it via cumbersome Bluetooth, data cable, etc.
