808 USB passthru not working

[Grantah]

Hi all,
I just bought a kr808 kit from vapor station. After getting started with everything.
I thought I would try out the USB passthru I put on the carto (the same one I was using on the battery)
And nothing connected it to several different sources, still didn't work.
The kit also came with a drip tip I havnt tried that on the USB device yet.
I'll try that when I get home today.
Am I doing something wrong or is it just not working?

Just to be clear I'm refering to the USB cord that has what looks like a battery on the end
Not the USB connector that plugs into the wall charger.

Contact the vendor. If it's not working they should be able to take care of the problem.

Though I have never seen an 808 one with a REAL inline battery (the battery-shaped part would have the weight of a battery and would actually BE a battery) - those have to charge some before they are usable. That kind can use a normal battery charger (or PC USB though I would not use a PC USB) and they charge a battery while you vape it.


The other kind does not have a real battery and just has a battery shaped handle. These usually put out 5v instead of 3.7v and draw too much power for a PC USB or a battery charger. These would have a battery SHAPED part for the handle but it should be lighter weight than a battery. This kind should use a 2-3 amp output (i.e. 2000-3000mA) USB to AC adapter, and these may need higher ohm cartos (like 3 ohms is LR relative to 5v)

I am not familiar with the specifics of the 808, but I do agree with Mud Stuffin (love that name). Contact you vendor asap.
Welcome to the ECF and best of luck.

If, as dormouse said, you have a powerful enough usb power source ... the usb adapter that came with your kit won't cut it ... then you should be able to confirm voltage to the connector using a meter. The center contact may need to be lifted slightly to make contact as well.

 

[dormouse]

True - if you ever have a problem with the center post of a carto not making electrical contact, you can take a skinny paperclip leg and very gently pry up around the post of the cartomizer - just a little bit on each side until all sides are lifted a bit. It does not have to be even - screwing the carto onto the battery or PT will even it.

Thanks for the quick responses. The one thing I didn't try yesterday, my iPhone USB charger. Connected it up to that, works great. Not enough power on the others I guess.

Make sure your charger can handle at least 2 amps. Most of them can't and you'll mess them up. You can find AC/USB adapters that are rated that high online. The one I have has 4 USB outlets, so I can vape off it at 5V and charge stuff at the same time. Most regular USB chargers are only rated for 500ma. The other thing you can do is get a self-powered USB hub that has an output of 2A or more. Then you won't be burning up your motherboard.

I'm using the AC/DC wall charger part. It has an output of 5v 1amp. I have serval of them, we'll see how long it last I guess.

I discovered my 808 pass-thru takes about 1.5 amp (1500 ma) when I tried to run it off my 1A auto USB adapter. I have since ensured that I buy only 2A rated devices (AC converter/Auto adapter). Both the chargers and passthru's work fine with them ( keep the old 1A converters/adapters dedicated to just the chargers).

I have some 5 volt automatic ones from Bloog (they have 5v and 3.7v versions) and some 5v manual ones from litecig and they all work great using some cheap Dynex 4 port hubs from best buy. I have one at the computer, one in the living room, and one on the night stand so I dont have to wear out my batteries when at home. They all occasionally have an issue where they stop working but tapping them a couple times on the desk/table makes them start working again. Dont know why.

It seems to be working well with the 1 amp, but I will defiantly keep my eye on the amp output in the future

I just did a quick comparison between the USB PT and my XL Batery. I can tell a noticeable difference between them, the XL Bat. Gives a better hit. I'll have to find something with a 2 amp output.

One of those self powered USB hubs sounds like the way to go, that way I can charge my devices off it as well.
Thanks for all the good info/help.
