5V PT wall adapter?

[VapeBoss]

Ahhh! Didn't think it was this hard to find the right wall adapter...lol

I use madvapes (tank) 100% of the day, Dual Coil Cartomizers, 3.0 ohms -LINK

Thttp://www.madvapes.com/Tank-Replacement-Dual-Coil-Cartomizers-30-ohms_p_3372.htmlhey have a2amp 5v wall adapter- LINK

Will it push 5v using DC's?

I'm still looking around for other adapters...

thanks ​

I actually ordered a couple of those yesterday for a mod I'm working on with a 1A charging rate. Yes, it's hard to find USB wall warts that have a 2A rating on them. The last ones I tried were rated for 1A, but they failed miserably sagging down to 3.5V with an actual 1A load on them.

The iPad/iPhone USB adapters are rated for 2.1A and they're cheap on eBay, but I haven't tried one yet. I'm not sure on those since they're not generic adapters. May be a problem, may not be.

I'll do a load test up to 2A on the MadVapes adapters when I get them and see how they do. If I remember, I'll post some bench test data for you. They should work well since you're only pulling 1.67A and the adapters are rated for 2A.

Right on! I just made my order(need parts anyways)

Haha...same story I did try 1a failed BAD!

Make sure you keep me(us) updated on the mod you are working on

The madvapes wall wort works but the overload or heat protection trips after a few minutes. I was using a 3 ohm carto. If you vape and give it time to rest it does fine.

FWIW....

Have you tried more than one? Maybe you got a faulty one.

Okay, got three MadVapes 2A USB wall warts today. I load tested them and here are the results.

Open circuit voltage was 5.2V plus or minus 20mV on all of them.

With a 2A load, voltage at the load was 4.7V plus or minus 20mV on all of them.

The reading under load includes the drop due to 4 feet of 22ga wiring, typically what you would find with a USB cable. With a 2A load, it's normal to see as much as a half volt drop over 4' of 22ga wiring.

I ran them for an extended period at 2A and found no drop-outs or other issues. They warm up a little, but run fairly cool, even at max load.

I removed the cover on one and found acceptable quality on the components and overall design of the power supply.

So, these units are well within voltage tolerance and perform well under load. I'm quite happy with them.
