"Review": Gyrfalcon ALL-40 charger

As for all my charger reviews, the usual disclaimer applies: I’m not an expert in electronics or chargers, but I’ve been using flashlights, batteries and chargers for almost a decade as a consumer. So I’ll give you my honest opinion on this product as a user.

I received the Gyrfalcon ALL40 for the review from Gyrfalcon.com

The Gyrfalcon ALL40 is a multi-chemistry 4 slot charger, powered either by a micro USB port or a 12v cigar plug with the provided adapter.

This is the box the ALL40 comes in

The ALL40 comes with a micro USB cable, a 12 V charging port, manual and warranty card.

The ALL40 can be powered through any micro USB port or via the provided 12V power adapter

The ALL40, in action.

As you can see the slots have a lot of room and length. The slides are stiff but run with smoothness.

There is only one switch on the charger, and it can be used to turn the screen backlight on and off, and for changing the charging current (250, 500, or 1000mA).

Every slot has its own display portion, showing the voltage of the cell, the estimated charge point and the charging current.

The charger works automatically: you put the batteries in, and the charger automatically detects if the cell is either a li-ion, nimh or nicd and starts the charge.
When using the micro USB port, the max overall current is 2A (250mAx4 or 500mAx4 or 1000mAx2); while when using the car charger 12V all channels could run at 1A (beside 250mAx4, 500mAx4).
If the USB power supply gives less than 2A and the charging current set is higher, the current will be reduced.

A couple of things:
- Every time you disconnect and re-connect the charger, the charging current will be set at the default 1A current, a current fine for bigger or IMR cells, but if you are using smaller cells, you need to lower it (either 250mA or 500mA),
- The charging current can not be set for each channel, only for all the slots at the same time. It means that if you are charging big and small cells, in order to safely charge the small ones, even the bigger cells will be charged at a lower speed.

A micro USB powered charger allows you to use it in the car even if you left home the dedicated 12V port, even if not at full speed (a charger with lower speed charges always faster than a charger without its cable).

Thanks to AntoLed for the camera help.
