So after I damaged 5 batteries , I bought an expensive Voltage stabilizer 1KW from Radio shack ($105). And I bought a Digital voltmeter to measure volts ,230 no problem.

I ordered a battery,USB charger and USB passthrough from Janity USA. I connected the Laptop to the Stabilizer ,charged the new battery with USB charger ,DC voltage! After 10 minutes the new manual battery blinked 8 times and died!! What the heck!! Why!!!!

I am glad that the USB passthrough is still working. But why all my 510 batteries get damaged like that!! The atomizers is good and doesn't get hot.

God doesnt want me to vape! I am really afraid to order a silver bullet or Provari , then after I pay tons of cash ,the batteries die again!!

I am reallyyyyyy glad I bought the passthrough! I heard bad reviews of it ,it is good so far. There is a 510 battery XL on the way from forever vapor ,but I am 100% that it will last only 10 minutes

WHat is the wall current you're dealing with in Egypt?

Best,

How long are you charging? What is the milliampere per hour rating of the battery and charger? What is the brand name of both? What vendor supplied these parts?

I would assume anything you bought from a USA vendor ( Janity USA ? ) would be calibrated for
110 AC only. You stated your wall current was 230? What is you laptop designed for, 230?

The USB charger is probably an AC/DC adapter made for 110. You have probably fried the
charger. If the batts are not getting warm on the charger, they are probably still good.

Sounds like you need a voltage converter to step down to 110, not a voltage stabilizer.

Voltage converter

And, I would use a USB adapter like this instead of plugging into your laptop.
It is a lot cheaper than burning out the MB on your laptop, which is possible if
the USB charger tries to draw too much amperage.

I bought the 230/110 converter too,I'll use it for the new XL battery. But I thought USB voltage is universal ?? Is DC voltage output from American laptop is different from Chinese one ??

Is the charger one that has a USB connector on one side, and the 510 connector on the other? In that case it should work fine plugged into your PC USB port.

I kind of expect you have a bad charger, else that your charger is built for an eGo or Riva 510 large mAh battery, and it is being used to charge a small mAh battery.

An eGo/Riva USB charger (USB on one side, 510 connector on the other) will say output 4.2V, 500 mA or so. You should only use this on a high capacity battery.

A normal 510 battery charger will say output 4.2V, 100 mA or so, a much smaller "mA" output. This charger is safe to use on either big or small batteries (though it will take a long time to charge a big battery).

A USB charger can be bad, things do break. If you're lucky the batteries may still be okay, just that they need a good charger. If you're unlucky the bad charger could have broken the batteries.

My Janity USB charger is Input: 5V 500 ma ,output 4.2 150 ma. Batteries is 3.7 from Janity ,probably less from 200 ma.

 

[Youmadbrah]

And ALL my chargers work from 110-240 AC/DC !! Its written on them!

 

[markfm]

Charger spec is fine, so likely it is just a bad charger.

 

[Youmadbrah]

Then this will make them 4 bad chargers!! Trust me I am cursed haha. I'll charge the 510 XL battery with the 230/110 converter and report back. Thx for ur help.

I bought the 230/110 converter too,I'll use it for the new XL battery. But I thought USB voltage is universal ?? Is DC voltage output from American laptop is different from Chinese one ??

That's a good question. I guess it would be safe to assume that USB accessories are universal.
But you are using it to charge something and you have to consider not only the voltage, but the
cycle rates are different. I don't know for sure how this would effect your charger.

The safe bet would be to use the converter with the USB ac adapter.
Even better, would be to get an adapter rated 2 amps or more, and use the
pass thru on that instead of your laptop. Like I said before, an adapter is a
lot cheaper to replace than your laptop.

Problems have been known to happen. If the PT draws too many amps, at best it will
burn out the USB port only, at worst it will burn out the whole motherboard.

Yes, if your passthrough is a "dumb" simple one, no inline battery, you'll be much better off running it from a dedicated 2Amp USB power supply, electric connector on one side, USB female on the other. The one I use is called an IQ Dual USB 2A, but others are out there (the box it comes in says 1.5A, but the actual USB power supply properly shows 2A, and I used it for many months with a passthrough).

USB is indeed universal, it is a nominal 5V DC. As long as a USB wall wart power supply indicates it can accept up to 240VAC and 50Hz it should be okay on your local power, but maybe you had a bad surge that somehow passed through the power supply and then fried the USB/510 charger. I have traveled a lot, seen 260VAC coming out of a supposed 230 VAC outlet on multiple occasions -- many devices do okay, but others fail.

Going forward, using your radio shack stabilizer would be good, or else it is okay to plug your USB/510 charger into a PC USB port (don't do this with the suspected bad charger, but with a new one that is okay to do).
