Been using mine all week - works REALLY well.
The batteries do drain quite a bit faster when using eject (12v) however I don't have to use eject that much so its no biggy. Most flashing operations these days use 5v.
I also use a cigarette lighter pass thru dc adapter and works great in the car flashing (no need to take the batteries out either like it suggests on the packaging)
Always worth keeping a spare set of batteries to hand. Only negative is that there is no recharge circuit but you can always have your own recharger to hand they are cheap enough (even tho the amps will be less with a rechargeable battery).
I use Procell batteries and bought them from xconsoles - very cheap and are made by Duracell so last quite well.
The switches are perhaps labeled a little ambiguously but once you know what they do its easy enough.
Operation with 2 x 9V batteries loaded:
- Power ON: SWITCH to BAT.
- Power OFF: SWITCH to AUX
- Battery power detected: (Green: good, Orange: middle power, Red: Low power)
(1) Battery icon switch to ON: Power level detect enabled and 2 LED beside battery will be shown on.
(2) Battery icon switch to OFF: Power level detect function off (saves battery life)
Operation with AUX power (Car power adapter)
- Power ON: switch SWITCH to AUX
- Power OFF: switch SWITCH to BAT.
The LED on molex port is telling ppl the power of the port is ON or OFF at that time. Green LED is Battery - Blue LED is AUX pass-thru power.
Total Power OFF would be AUX Switch to ON and Battery Level switch to OFF (Should be no LED's at all)
PROS:
+ Works exactly as advertised.
+ High quality design and build
+ Battery level indicators very accurate
+ Includes molded Molex to Molex cable
+ Works really well with CK3
+ AC/DC pass thru is great if you are low on batteries and have no other molex PSU.
+ Comes with a bonus USB charging cable (charges my Galaxy S2 great!) - nice surprise as this wasn't advertised in the original specs
CONS:
- No recharge circuit
- Batteries drain faster when using eject (however - as expected)
- USB Charging cable doesn't work with ipods / iphones - however we are told that a specific designed cable for Apple products is being released shortly.
Overall its very well made and very professional.
I give this a solid 4.5/5
