Cheapest pass through i can get my hands on?

Many eGo batteries, including the original Joye eGo, use a regulated voltage chip. Regulated eGo batteries put out 3.2 volts all the time, whether fresh off the charger or close to needing a recharge. Other eGo-type or eGo-clone batteries are unregulated, so they put out whatever voltage the battery provides. This type will provide more volts (typically 4.2 volts) with a freshly-charged battery, but gradually less as the battery drains.

My first PV eight months ago was a 750mAh Riva kit from Liberty-Flights, which had unregulated batteries. So I've never actually vaped an eGo that runs at 3.2. I don't vape at 3.7 volts much anymore, preferring the higher and adjustable voltage of my VV boxes, but those two Riva batteries are still good and going strong. I keep them in my car as emergency backups for a 5-volt passthrough that runs off a 2-amp usb auto adapter.

I'm not completely clear about what you're confused about (your confusion is confusing me <grin>). Maybe I can clear it up.

eGo batteries are indeed a 3.7v battery, but they can't put out 3.7 volts. They have a regulator that brings them down to 3.2v. That does two things - It provides a really consistant vaping experience due to the voltage not slowly dropping off as you use it - and it can help the batteries last a little longer between charges.

The eGo passthrough is just an eGo battery with a USB charger built in. When plugged in to a USB power source, they don't reset the circuit and disable the button, so you can use them while they are plugged in USB. - The voltage provided by the USB power source enters the battery. It doesn't bypass the battery and circuitry. So, when you vape while it is plugged in, you're still vaping with electricity provided by the battery.

Since the Rivas were mentioned, I'll explain them a little bit, though as far as I know, there isn't a Riva passthrough like an eGo passthrough. - Rivas are an eGo clone, but most of them are not regulated. There are some 650 mah Rivas that are 3.2v regulated, but I've never had one. The bigger Rivas - 750 mah to 1300 mah - are (as far as i can tell, anyway) all unregulated. So, they come off the charger fresh at 4.2v and drain down as you use them to something around 3.5 or 3.6v when they die.

I hope that helps.

lol don't worry you didn't confuse me john was confusing me because of how he worded his questions!! lol no offence oh and my riva is 650 mah 3.2 regulated ordered it about a month to soon....
