Help ! Fan for helmet question

[RLH2515[TK]]

Ok so can anyone please tell me why these fans will run maybe 30 sec then shut off. I use this pack for other fans and it works great. Now all of a sudden 30 sec and it shuckss off.

I had the same issue. Bought an anker power pack and after 6 hours the two 5v fans still run.

Some power supplies have a build in load requirement. Not enough load the battery shuts off to save battery life. The Anker Pro had a 50mAh draw requirement. Your battery pack may have the same issue. You'll need to contact the mfg to confirm.

This.  I use an Anker Astro 6700, and it works flawlessly with both fans running for hours.

Yeah I used this with no issues until recent. That's why I'm asking the pros thanks guys.

So after some research last night I discovered my original fans are 5v .235 amps and 1.18 watts. My new ones are 5v .10 amps and .5 watts. I was able to successfully run my new ones on a small 2000mAh for 4 hours on a less then full charge. Needles to say I'm happy now.
