The Arizer Air

Both batteries I charged read 4.20 on the charger and 4.19 on my harbor freight multimeter. So the actual number could be neither of those lol.

Interesting, sounds safe enough on the face of it. However, several of us have measured 4.25 or so. A small amount for sure, but IIRC Li-ions 'hit a wall' at the top end and typically past that each .1 Volt cuts the lifetime by more than half?

I'm able to determine the end of charge since I'm monitoring the actual input current (which normally tapers from about 800mA down to about 100 before dropping like the proverbial rock. I never paid much attention to the light. I suspect the others reporting 4.25 or so are using the light?

I'm surprised if yours is that much different. How much do you trust your meter? Assuming you're using a 20 Volt range, the typical specification for 'good quality' DMMs is about 1%, plus or minus a count or two. FWIW many times the displayed values on chargers are more symbolic than accurate. And, of course, as a practical matter you can't specify a 4.200 Volt charger and expect low cost. Since the voltage is fixed in the IC manufacturing process what you get is a 'window' of acceptable values, typically 4.15 +/-.05 Volts. I would not be at all surprised to find out the above charger was terminating at say 4.12 Volts (in range) but telling you it was 4.20. As a practical matter, in most cases, anything from 4.10 to 4.20 is a shippable product....but the customers would rather see 4.20 than 4.16?

Fun stuff, if it's the sort of stuff that interests you. Otherwise........



Interesting.....you're sure the length is right? Play station supplies were used (with some few problems) on Solo for PAs, the connector fits fine there and the voltage was right for Solo. However, many of those connectors are not long enough to work on Air, and those I have that do are doing so marginally. IIRC it's like .7mm. Not much. The 'factory' connector is a fair bit longer:

At the top is the stock charger plug, in the center a typical USB to 4mm cable. At the bottom is my hatchet job on the connector to get it to work. Be advised twice now I've been unable to trim the shoulder back due to construction of the plug. Some types can't be cut back.

Bottom line is Air is atypically long for EIAJ-02 connectors......be advised?

Regards and best wishes.

So the one ive ordered was from Amazon, I asked someone to confirm the length of exposed metal including tip and they said 12mm.

I am away from home for a few days and don't have my AA. What is the length of the exposed metal including tip on the stock charger?

Thanks

OF said:

I make this one at 12.5mm. You're probably close enough?

I just had my AA delivered right now (ordered it from PIU a week ago) it seems I have the model with the battery level indicator as well.

I'm very happy that my package slipped through customs, so not having to pay import tax or anything else, I saved a 100$ compared to buying from a EU store

I'm dry today but tomorrow I will take the 100$ I saved with me to Christiania!

Where did you getting it deliverd to, the US?


Do you guys normally have to pay import charges from Canada to US?

Does anyone have an a PSP charger either wall or USB that they could test the fit? Probably best not to turn on if using wall version as output could be differnt.

Thanks

I have a bunch of 18650 batteries mostly Sony and efest and the d4 charger. Been using for my ecigs for a while and they work just fine in the air.

Just leaving this in here. Let's just say I am very pleased with my first vape from Arizer. Also, I know many members are starting to get the picture, but those round screens from eBay that @Sinclue posted made me love my Air. At first I thought the vape was just "good" because herb particles would fly in my mouth and when that wasn't happening, the airflow was clogged/restricted. The screens solved both of those problems.

yes they may work but you will be giving up your warrenty. Not something i would do, since they offer 2 yrs on the unit and a lifetime on the heating element. 17 dollars for extra batteries isnt much to have a piece of mind. use at your own risk

Its an oldie but goodie fluke 12 multimeter so I believe its pretty trustworthy. I will make sure im using the right range when I get back. @SlightlyStonedSD happen to have a multimeter to double check the values?



I second your experience. Screens make it way smoother IMO. Nice water tool, where did you get it?

I see where you're coming from, I'm not too worried. The battery that comes with it is 5A and my current are 35A.

OF said:

Cool. The point I was (no doubt poorly) making is on a 20 Volt range (2 is short for the job) you only display hundredths of a Volt on a typical 3.5 digit DMM. So we're interested in just a few counts here. At 4.0 Volts, give or take, one percent is four counts plus say two for zero tracking errors (a typical spec) and we can be 60mV off (six counts, up or down) and still be in spec for the meter.......if it's still on spec.

At some point it gets to the level of the student that measures a voltage to one percent across a five percent resistor, grabs his trusty calculator and tells you the current (via Ohms Law) to 6 places.....

Fun stuff.



That spec is useless in Air (where 4A is maximum ever needed), but comes at the expense of other stuff (like capacity or service life) we might rather have? It's all compromises, the rules are known.

It's something like driving a supercar in rush hour. Potential performance you can't take advantage of.

I know that already. I use the 35A ones in my ecig devices before I picked up an air. However I know I can't use the air battery with any of my other devices.
