Here's a few beam shots showing the USB Charger Flashlight in action. The comparison flashlights were the new Citycat Big Head K8 offered by CNQualitygoods and a Yezl M6X, also offered by CNQ. It's not possible for me to get a tail-cap reading on the USB light due to the battery carrier configuration. But it's rated at 800 lumens.
The Big Head K8, is rated at 900 lumens and driven from a LD-29 driver. Tail readings were 1.20a HIGH mode with 2x18650 and 2.40a HIGH mode with 1x18650. No difference in brightness between battery configurations. Tint is NW /XM-L T6-3C.
The Yezl M6X is rated at 800 lumens and rated at 2500mA. Actual tail readings were 1.88a. Tint is CW XM-L T6.
Nice addition!! I really like the parallel 18650 configuration, and the built in USB charger is a very nice/unique feature. Looks like a must have for anyone who travels with a laptop.
I know with the Iphone the wall charger is faster than the computer USB ports..500ma vs 1000ma..the Iphone senses the source and charges appropriately..maybe the Apple charging port is capable of the "fast charge" mode and has the correct variables to make the Iphone charge at the faster rate..the other USB port will probably charge it just at the slower rate..
just guessing from my experience with my Iphone though..
The flashlight has a regulator that can sense charge requirements from 300mA-2500mA. The home charger for my IPAD1 and IPAD2 has an output of 2.1a, but my Ipod touch requires 1a charge current. I don't have an iPhone, but I'd imagine it may require similar charge current as the Ipod Touch, perhaps a bit more. I'd have to assume the "Apple" side has additional circuitry for varying Apple device charging requirements.
The resistors (and therefore voltage at the data pins) vary between the generations of devices and is used to communicate the current that the device is capable of providing to the idevice.
It's very wobbly with the 2 main USB dust plugs I used, but without them it's totally rock solid. I may look into trimming down the dust plugs I used so it tail stands correctly with them in.
How about direct links to the two companies I purchased them from some months ago. As I recall, both were received about 2 or 3 days after placing the order.
Hi Dthrckt, they are perfectly secure no matter how much handling you do thanks to the soft rubber each type is made from. You won't have any problems with them falling out.
