Evic easy head issue!

[Kylum]

Hi, I got a easy head yesterday. I have found two issues with it so far. The first: the unit will only charge my Panasonic to 4.17v which is fine but not fully charged. The red light also goes dim not green. Is it not suppose to turn green? As I have read on a sellers websites that it does go dim red on charge complete. But that website is the only one that says that. (Can't find link now) since that web site said that I went and checked at the joyetech web site to make sure it's not a clone and its not.


The second : When in regulated mode when testing with a multimeter it is showing full batter voltage and not 3.3v. Has anyone else had this issue at all? Whats going on here? Is this simple head smart enough to adjust to different heads? Possible reason I'm getting full battery voltage in 3.3 mode. I doubt this based on the joyetech website stating "constant 3.3". Plus a 1.8 ohm in my kanger pro taste a little burnt while in this setting.


any thought would be much appreciated. I am taking it back to where I bought it. The 18650 I have in there is a Panasonic 2600mah unprotected. I went with the unprotected be cause joyetech states that the head itself is protected for short circuit, over discharge, and over charge.

First concern, would not call .03v an issue as much as a slight variance. Are you measuring battery only or through head?

Second may simply be a Load/No Load variable.

LED color - no idea

The USB charging port located on the side has a LED that will illuminate red when charging, and go out when the battery in the eVic is completely charged.

Perhaps you are disconnecting while it is in reduced top off operation.

Yeah im not to worried about the .03v could just me my multimeter ect. I tested the battery out of the device.

Second may simply be a Load/No Load variable.

I was thinking the same thing but even the same setup on another device at 3.5 taste just fine. Plus joyetech says constant 3.3v so im unsure, and not sure how to test with a load. I guess if the store says its still good i will test it with a 3v fan i have at the house.

Straight from joyetech site says "eVic easy head retains the design of side USB port, providing a convenient charging way. The LED light is red when it is charging and will turn green when it finishes charging."

You might be correct about the reduced top off operation. I will test that later today.

thanks for the fast reply

Also, Don't put to much trust in OEM website accuracy. Sadly this is one area where the Chinese are horrible at proofing. Often new items are placed in old product slots and old Data is not fully updated/removed. Very very common

Well I went to the shop that I got it from. They tested it with a multimeter and came to the same conclusion I did. It was getting high voltage at the low voltage setting. They manager put his tank on it on low setting and stated that it should not perform this well with the higher resistance head he had in it. He was unable to notice any difference from low to high setting. He tested several new ones and they all did the same exact thing. His conclusion is that they do not perform as advertised. He wouldnt even try a lower resistance head on it because it would definatley burn it. He was happy that I brought this to his attention. He didn't say that he was gonna pull all of them from all of their stores. But that's what I took from his conclusion. He is gonna do further testing.

My conclusion is this thing is a dud

 

[crxess]

Well, you took a solid course of action, many do not. Hopefully he will contact Joyetech and they can investigate the issue. Very likely a Defective batch of chips that got out.
Joyetech is good about correcting Known issues.

i dont know how accurate this is as i got it second hand myself, but the LED in the begining DID used to turn green ( the first one i got that blew up an hour after i received it new had the red/green LED), but due to problems with the original board they changed it and the layout of some of the components. also, the voltage needs to be checked under load.

i own several evics, but i have a friend who just purchased a Smok SID awhile back. you can buy them for about 35-40 bucks depending on where you go, but from what i can tell its pretty much just an EVIC with a different digital screen and control setup. VW/VV unit, uses the same battery tubes and top rings as the evic,ect. might be worth looking into.

I have one. LED does not go green. It just dims.
I returned mine once because the ego threads were bad. I have a replacement now. It works fine. I don't use it anymore. It's just for a backup in case something happens with my regular evic head.

 

[CaliGrower]

i had a couple of evic heads freak freely on me and burn out in the past jack, both times o found that it was due to the rubber piece under the center post in the head busting and shorting against the case. in both cases i pulled the center posy up, unsoldered it, put a heavier duty insulating rubber under it ( out of the bottom of a couple of protank burners by the way, they fit perfect) and resoldered the center pin in. gave one to my bro, and the other one i repaired is still going strong. dropped it off of my harley twice now at 70 miles an hour . broke the tanks both times and dented the heck out of my battery tube, but the head itself is still going without issues, works great.

the evic easyhead on the other hand is questionable. the first one i had literally burned up within a hour of buying it. i just a couple days ago finally got my replacement in the mail, and it doesnt seem to me to be putting out the correct voltages either. i have not checked it with a meter yet, but in regulated mode, i havent been able to get a decent hit off any tank/burner. in unregulated mode, it will work fair with a 1.5-1.8 burner, but even on a low ohm burner in regulated mode, barely any vapor at all. ive even tried several different batteries of different milliamps and it is still the same. ill probably give it to my son in law and let him ..... with it a little.

I am also having issues with easy head. It is working, but on high voltage on both modes. That means it is unusable for genesis with 1.7 ohm at 3.3V or other coils under 2.6 ohm.... I bought it for backup and for taking it out/on the go, cause with the 18350 tube this thing is really small (82mm) and pocket friendly. I hope the joyetech will resolve the issue quickly.

Meanwhile i contacted joyetech and they will send me replacement head to test it out and compare to the one i have. They have great customer service and quick response time!!!

That's because it isn't 3.3V but 3.7V regulated like the eGo-T, both the eVic easy and the iSmoka iGo head (same thing but for smaller diameter 16650 batteries). The unregulated setting is whatever voltage your battery happens to put out.

I thought is was 3.3 V Regulated. Like all joytech ego batts

 

[Liquidrino]

So did I.

I took some measurements over the day inline with a 2 ohms carto, and it turned out that the voltage is always unregulated, regardless of what you're setting it to.

Another lemon I guess, but the voltage on my eVic easy was 3.6xV on the regulated setting.

I have a new Easy Head here - it blinks 3 blue lights and doesn't fire. If I click it five times to turn it off or on, all I get are 3 blinking lights. I've changed batteries, attys, etc. it still just blinks.

 

[MsComptrtchr]

I have to agree on the great customer service from Joyetech. I contacted them about my DOA Easy Head and they responded within hours. By the next day, they got me in touch with Cignot in the US and they are replacing my head. I am very pleased. Do keep in mind that since July, they have a new warranty policy - 3 months: replacement within the first month, repair within two months. Having said that however, they are still replacing this head even though I bought it in August (was saving it as a backup and never tried it until the other day.)

I'm really happy with Joyetech and it reaffirms why I have 3 eVics, lol.

You have to remember that this is a PWM device and standard meters can't get a correct read on it in PWM mode. Voltage readings with a standard meter will start at 4.17 because it's the first thing they see, while the PWM voltage is actually bouncing all over the place to produce an averaged voltage.

Hell, I have a meter designed to read PWM devices and it can't even figure out what Joyetech has going on here. It knows it's a PWM device and goes into the correct mode to read it, but it can't determine what frequency this thing is running PWM at. I'm actually going to contact the designer of the meter to see if he is aware of this and ask if there will be a firmware update for the meter to correctly read these heads.

eVic's chipset uses a 104.9KHz frequency, PBusardo did a lot of number crunching on it. Scroll through the slide show and you'll see all the numbers the eVic has to offer.

--EDIT--

Not sure about the easy head, I'll do some digging and get back but there really shouldn't be that much of a difference in the chipsets.

Funny someone else said something about it blinking three times. Bought it as an emergency backup week and a half ago 2 weeks ago tops and it was working fine up until the other day. Now I charge it and it continues charging forever. Throw my battery on a Trustfire charger and said it was done charging. The damn thing doesn't do anything except for blinking three times. When I put on the charger blinks 3 times when i go to take it off the charger it blinks three times when I put on or take off a tank on it blinks 3 times but it won't fire anymore for anything

How low do you run your batteries before charging? Also, is the evic a device that maintains the same vape till the battery dies?
