This one
Manual Switch Passthrough for JOYE510 In 3 Colors [JOYE 510] - $9.00 : Healthcabin Electronic Cigarettes - Wholesale and Retail--

or this one?
510 Manual USB Passthrough in 4 colors(With no Battery) [510] - $9.00 : Healthcabin Electronic Cigarettes - Wholesale and Retail--

Does anyone know what voltage the one with the battery is rated at, i think its 3.7v?

Can anyone recommend cartos to go with them? (from health cabbin?) Thanks. I'm guessing the dual coils? Does the voltage matter in terms of flavor? Like 3.7v or 5v?? So many factors.

If the passthru has a battery, it will put out the typical 3.7V...the advantage is that every hit will be as strong as a battery fresh off the charger.

If it does not have a battery, it will put out whatever power is supplied to it....which means you can get 5V IF your power supply can provide enough amps--this works well if you have a USB power supply rated 2A or better, but many of them cap out at 1A or lower....so you are probably better off getting the one with a battery, or, better yet get one of these: 1000mAh Joye eGo USB Battery(Passthrough) in 4 Colors [Joye eGo] - $20.00 : Healthcabin Electronic Cigarettes - Wholesale and Retail-- It has a mini-USB port on the bottom which allows you to use it like a 3.7V passthru and vape while the battery is charging, but its also a 1000mAH battery so it is ready to unplug and go all day.

In got the 510 manual 5v PT and added on a 2amp wall connection as advised to avoid frying my computers USB ports. The unit was worthless. I would suggest a PT with a inline battery. Paid $25 with shipping for the Ego PT with inline battery mentioned in this thread (with shipping) then found it for less from several ECF suppliers. I've gotten scads of free knowledge here and hope they stay around for others. Supporting ECFs advertisers can help insure that.
