Tekkeon Battery + 900 LED Test

• • 16 Comments

This test is in reference to my eariler post (found here). So I charged up the Tekkeon overnight and setup this Timelapse test. The reason I used a Timelapse method was to determine if the light output would change during the duration of battery use. I locked the exposure on the camera to 1/25th F/4 and ISO 100 to see if the light output would dim towards the end. The big 900 LED light was set to full power.

It was interesting to see that the Tekkeon remained at a full 14 Volts during the entire test, and when the indicator was down to the last bar, the battery just shut off instantly. If there was a voltage drop during the test, the 900 LED light would start to dim (it didn't dim). Total run time in this test was about 1 hour 6 minutes (1:06). Keep in mind this is a larger 900 LED light on full. If performed at lower output, or for smaller lights like the 600 LED, or 312 LED at only 12 Volts, it would probably run for several hours.

    @Thinley - I would not suggest it for those types of lighting. It will cause CFL to flicker, and Tungsten will probably just overheat the inverter.

    Thanks Emm for your help but does it work for continious lighting tungsten or flourosent 600w to 1000 w thanks again for your helpful suggestion!

    @Thinley - The inverter can work to power 110V items, but on some lights or high powered items it will cause flicker. The power coming through is not always clean.

    @Kyler - Interesting, not sure about those. I have indeed verified that the Tekkeon battery works like a charm when I switch the voltage to 5V on the dim switches. The Tekkeon is a big battery though. httpss://cheesycam.com/tekkeon-mypower-battery-pack-5v-19v/

    I was also looking at these Trent Packs:

    Hi Emm,

    I'm still trying to figure out the Asus Wicast wireless setup so that it can run on battery power alone. The 5v/12v $20 batteries don't supply quite enough power to make the units function, although the lights do blink. Do you have any other cheaper solutions for this? Is there not enough amperage coming from the batteries?

    Would this battery solution work better, since it specifically says it outputs 2amp?

    Or if not, maybe the Duracell Powerhouse batteries?

    Thanks for the help!

    @Nicholas - Thanks for the calculation. One of the questions I had was dimming during the duration to see the battery's performance. I'm very happy with the way the Tekkeon works. We had to use it out on the field to also charge up our GoPro's and the Sony HX9V (uses a USB charger) at one point.

    It's quite easy to calculate, the Tekkeon battery is rated at 58 Wh (watt/hour), the 600LED is rated at 36Wh so you will get 58/36 = 1.6 that should be about +/- 1 hour 35 minutes. I haven't been able to find any Wh data on the 900LED but given the test it probably has a draw of 54Wh.

    @HD-Tography - The power brick that comes with it says 6A output, but I don't know if it really draws that. I'm sure that's just what the brick is capable of handling. No other info on the LED.

    Yeah cool, that's not too bad 😀 Thanks Emm, good review... I guess I meant what kind of wattage/power does it draw? Should say on the back of the light, if ya happen to remember to check one day...

    @HD-Tography - Yeah damn MAC screensaver! I didn't notice it until later, but luckily caught it before the test ended. Wattage? Not sure, but we compared it next to 1K quartz, and it was very comparable. They are pretty bright and when you can move them close to a subject, we've used them outdoors for fill lighting in mid day.
