This is my “review” of the Charger ENOVA Gyrfalcon All-88.
Melody, from Gyrfalcon ENOVA kindly sent me one of their All-88 chargers for the review.
The usual disclaimer applies: I’m no expert on chargers or electronics, but I’ll try to give you guys my opinion as a user.
The charger comes in a cardboard and plastic box, with the power supply, the charger and the english user manual 
The all-88 is a nimh and li-ion charger (3.6V LiFePO4, 4.2V Li-ion, 4.3V Li-ion, 4.35V Li-ion).
Its most distinctive feature is the 8 independent slots, each one with a separate display. For each slot there is a switch that operates the slot, plus 2 others in the middle (FN and C-V). Each switch has a red-blue LED inside. Blue when it is charging, flashing blue when requires intervention and red solid when it is charged.
The 8 slots are very broad and can host 26650 and C cells. 
Size comparison between Nitecore D2 and Xtar VP6.
The springs are strong and there is no need of lubing the rods. The length for the cells is enough for all the 18650 cells that I own, here you can see some of the protected one. Here is a panasonic NCR18650B with PCB and a Xtar 2600mAh… both considered among the longest 18650 cells. The max space is around 72 mm, so you can see there is still a bit of extra space. 
When the negative contact are resting, the distance between them and the positive contact point is 30 mm.
Rails and the positive poles have holes with threads that allows to mount the 4 spacers (that comes with the charger), allowing the charging of smaller cells. 
You can mount the spacer sas you wish 
The positive contact point has a small raised bump, so flat top cells (like unprotected Panasonic, LG, Samsung… fit). If the battery is smaller than the contact point, there is still contact if the battery is button top (like these AAA). 
The display with the digits and simbols is orange-amber, and easy to read. It has a backlight. In the picture it shows terribly (because I’m a terrible photographer and it is glossy), but it’s very clear and easy to read even during the day and at a wide angle of view. 
The backlight turns automatically off with a timer after a few minutes, while the coloured led under the switch will stay on.
The display is split into 8 equal portions. Each says:
- Voltage of the charging cells (this is not the actual voltage reading, it says what cells are you recharging: nimh=1.5V, li ion 3.7 volt=4.2, li ion 3.8 volt=4.3)
- Charging Amps
- Battery level
- Actual reading of cell’s voltage
- Charging time
The slot are indipendent, for each of them you can set the 2 charging parameters: Voltage (again, it says the chemistry of the cell) and Amps (0.1A, 0.25A, 0.5A, 1.0A). It is possible to charge al the slot with 1A current at the same time.
The settings for each slot are not memorized. When you turn the charger on the default setting for all the slot is 1.5 V (nimh), 1A.
Now, if you want to charge more cells with the same settings, there are some shortcuts that can copy-paste the settings, or that can quick-set a default combination.
UI Single slot operation
Insert the cell and click the slot switch. In this moment we have set the voltage menu (you’ll see the >> pointing at volt). Each press of the slot switch will move 1 position further the indicator (1.5 -> 3.6 -> 4.2…). To set the A, click the C-V switch, and the arrow (>>) will point at the amps of the selected slot. Click again the slot switch to move the Amps settings.
To start the charge, click again the C-V switch (if you were in the A setting) and keep the slot menu pressed.
Each slot can be individually set.
Quindi, se dovete impostare 7 slot con gli stessi parametri di carica e 1 con parametri diversi, conviene inserire e far partire prima lo slot con la batteria “unica”, e poi con la funzione sopra descritte di modo che si programmino tutti gli altri slot, che non sono attivi.
Copy and Paste
It is possible to copy and paste the settings of a single slot to n adjacent slots, for example from 1 to 2, or from 1 to 8, or from 4 to 1…). To to so, set the slot to copy, then keep pressed the switch of the slot and press the switch of the slot you want to paste the settings. The charge will start automatically. If you have an adjacent slot already working, it won’t be affected.
8 slot shortcut
Keep pressed FN switch and click C-V switch. Now all the slots have been set to 4.2 volt, 1Amps.
Keep pressed FN switch and click C-V switch twice. Now all the slots have been set to 4.2 volt, 1 Amps.
Each press of the FN switch followed by C-V press, will advance the voltage settings for all the slots.
The charge will start automatically. If you have a slot already working, it won’t be affected.
If you think 8 slots are too many… you only need a couple of big lights (TM16GT and ETSX25L3) and a spare smaller light. And there is no free slot. To me this is a realistic flashlight kit that I bring with me during the night walks in the wood: a floody light, a throwy light and an headlamp.
My thoughts
Once you get used to the unique interface, you have a charger that can work 8 slots at the same time, 1 amp each. The charging current can be set in a wide range of settings, 4, that works from very small cells (where 0.5C is a bit high) to the bigger ones. I wasn’t able to put the 10180 cells in other chargers but the one especially made for them, or I had to work with cables and magnets because the cells were too small, or the charging currents too high. Here with the spacers supplied, 2 18180 will fit, and the 0.1 A charge is acceptable.
I’d like to see a small compartment to keep the spacers when not in use. Spacers are a bit tricky to screw in place: the holes are very small and the space for twisting them is limited.
Being able to charge different types of li-ion other than the widely owned “4.2” is a nice thing to have. Owning only nimh and 3.7 volts cells, I’d like too see a shortcut to hyde the other type of cells during the setting of voltage for single slot operation.
Given the broad diameter of the slots, that can handle C and 26650, the smaller cells needs to be inserted carefully in order to touch the positive pole. I’d like to see a bigger positive pole button.
In this aspect the all 88 is very good: can charge many cells quickly at the same time, AND can do the same for small cells at correct currents.
In the first prototypes the led colour were red (charging, need user intervention) and red (charging finished). I find this choice closer to my habits and the one of other chargers.
I’m happy to own this charger because it can handle many cells, is ideal for charging a lot of cells before a sudden night walk in the woods, or for charging multiple set of cells that I use in my review. With the 1A setting I can do things a lot quicker when I’m in a hurry (pretty much all the time)
According to ENOVA, the 4 slot version will be released during this summer. For someone who doesn’t need all this slot, it should be a more suitable version, since the volume of the charger should be half of the all-88.
Thanks to: AntoLed for lending me the camera.
Feedback is always welcome.
