I hear ya. Product description states: “Integrated 3-in-1 safety chip: Extra charge, discharge and short circuit protection, no over-charge, damage to lithium core or extreme temperature,” but how that works in practice is anyone’s guess.
If the ad is to be believed, its 6000mah. Its likely a pouch pack. if we are lucky its 2x18650. Given the thickness, I’m inclined to think its a pouch.
You have to use the vipon code at amazon and put it in the promotional code box at checkout to get the discount.
Unfortunately the code want be available again for about 13 hours.
Of course I opened it. It had screws. Isnt that what you are supposed to do with something you just purchase? Open it up and see whats inside/how it works? Thats how I grew up at least.
BTW, mine was completely dead when it arrived. The light wouldn’t turn on. Charging it now. It was initially only pulling about 0.1A from my USB wall plug, but after a while it went up to 1A.
FYI, when pulling 0.5A current from the USB port, I got 13,650 mWh out of it. This translates to 3,689 mAh capacity @ 3.7V. Alas, even though the port would no longer supply current at this point, the light would still turn on.
I wanted to initially measure capacity using 1A current, but the USB can’t deliver it reliably. If you try to go higher than about 0.9A, voltage starts dropping notably. Anyway, not a big deal. I didn’t really buy it for the power bank function.
As a portable work light, it works fine, other than the blue/red strobe/disco mode. Wonder if Police would take an issue with it if they saw you running it on the side of the road at night.
