Lumintop 14500 question

I just receive my Tool AA. The 14500 doesn’t charge with my USB C phone cable. It does charge with the USB C with the USB A on the other end.

Is this normal?

Most probably yes.

So far ( I don’t have many) all of my USB rechargeable cells would not charge USB C to USB C. But A to C works. So your situation is what I would call normal.

Highly likely that your power block can’t charge that battery with type c, you need to try another. Was same problem with some phones.

I guess it’s normal. I did a Google image search. All USB C rechargeable batteries comes with USB A to USB C. I didn’t see any USB C to USB C.

I wonder if the battery can handle a faster charge by using a USB C to USB C cable.

If my cable can charge my phone with the larger battery, I don’t think the wall charger/power block is the issue. It could of been design this way for a reason. Probably a slower charge.

Venom, i have charger with type a and type c in. It can charge one samsung phone with type-c to type-c cable and can’t charge another newer one. But on another charger same cable same phone work well. At least topic starter can try, maybe it will work with another charger.

I just tried another USB, C wall charger with the same cable. Doesn’t work.

The fact that Lumintop 14500s won’t charge with C-to-C is not correct, but it is normal. I’ve found this is the case with Acebeam 920mAh batteries as well.

It's common for "cheap" flashlight, to not support the PD standard, and not have the two resistors on the USB C connectors, telling the other USB C device, that they want power.

So they Just don't work with USB C to USB C.
Almost all My USB C flashlight, only work with USB A - USB C cables.

Any suggestions on a good USB, C to C cable? I been wanting a spare cable.

Thanks for the replies, everyone!

I don’t have any suggestions based on experience. The ones I have are all USB 2.0, and therefore have only 5 conductors in them (through there may be more than one VBUS or GND conductor in there; I’ve never cut them open). I only have one that is rated for 100W and I hate it; it holds every bend that was in it when it came out of the package, and its outer sheath is kind of sticky.

If you are just looking for power rather than high speed data, the Anker Powerline cables look nice, especially the Powerline III, but they are USB 2.0.

I’ve been meaning to get at least one USB 3.1 C-to-C cable just for experiments, but I expect they will be thick and stiff because they have at least 9 conductors. I’m wondering if I should jump straight to USB 3.2, but that will be even thicker with 20+ conductors.

USB sure is getting complicated!

Isn’t there USB C cable advertise as kink free or no tangle?

For Anker I been looking at this one. Supposed to be tangle free. I think this is the same one you mention.

I was actually looking at these:


However, I like those bendy silicone ones you found.

Yeah, USB ain’t always as U as purported.

I didn’t even seem the ones you link to on Amazon.

I found this in the Q&A on Amazon about the Lumintop 14500. Copy & paste

“It will light up red when charging and green when it is fully charged. And I would also like to note when I plug into certain USB C fast charging cords it will not work with the battery. It seems to only work slower/ cheaper USB C charging cords to charge properly.”

It look like someone else has the same issue


I received the Anker USB C to USB C cable, the bendy silicone one.

Still doesn’t charge. I’m guessing the 14500 doesn’t like fast charging.

It's like I said earlier, the battery doesn't have PD support, and it doesn't have the two resistors to tell other devices, that it wants power.

Buying a PD USB C to C cable, won't change that...
It will not work.

Just buy normal USB A to USB C cable, and that's it.

Ps. And the recommended max charging current of 14500 is usually rather small. usually 0.25-0.5 A (and the 0.5A is usually for the high current ones)

Yeah… regular charging of an 18650 would be fast-charging a 14500. I wouldn’t try to charge a 14500 any faster, unless you want a warp-core breach.
