Fenix charger PSU

[terra3]

Hi there

Picked up a Fenix ARE-D2 charger recently. Like many, it comes with a charging cable but relies upon user to provide the AC power adapter.

I have a handful of reasonable quality adapters (more Anker than any) but none match the 5V/2.0A input spec that the charger documentation and Fenix have explicitly stated to me is needed for the charger. The only true 5V/2A ones I see are knock-off offshore brands and not the brands I typically hold to. I'm not good with using those.

Not to be a Doubting Thomas in this, but how strict is this spec for the adapter in practice? I have an Anker 5V/2.4A adapter. Any safety or product reliability issue in using this slightly off-spec adapter with this charger?

Thanks

I'm no electrician or specialist, but as I understand it, the charger spec for amps is the max capacity it can provide. The device to be charged will pull only what it needs: at or below 2.0 amps. Using a charger rated at 2.4 amps likely won't damage the device. The charger rating does not mean will "force feed" a constant maximum amperage to the device.

Essentially correct, and also actually a positive, not a negative in this case. Having a bit of 'headroom' or 'margin' in such situations is essentially a good thing. If for some reason the ratings are marginal &/ or the device (charger) momentarily draws slightly above its input current rating, that 'margin' will help keep the power supply output voltage provided to the charger stable and within spec.

Thanks folks.

And I should add as it is a welcomed follow-up from them, received another response from Fenix as well just a few minutes ago indicating yes . . . good for this. Specifying anything within the range of 2A - 3A good, but avoid higher currents. And interestingly enough, they indicate any brand's adapter other than Apple good for this.
