Battery Pack Question With USB Passthru

[wv2win]

I was about to order the battery pack that Sun recommends when I ran across this Macally JBoxMini in Frys on sale for $25. Has anyone tried it or if not do you think it would work just as well since it is about $20 less expensive. One note, the specs in the manual with the product state that the "Battery capacity is 1700 mAh" whereas their web site states Output Current 1000 mA. I don't understand why the difference or if "battery capacity" and "output current" are two different animals. Your advice is appreciated.

As long as it is 1000ma it should work just fine...

What kind of USB passthru do you have? If its like the one from PS, that does not have a battery built in, then this battery pack will most likely NOT work. If you have one with the battery built in then it will work.

OK FACTS: (2) Different Battery mAh What this Means:

1) "Battery capacity is 1700 mAh" Is That is The Actual Battery Size In mAh & Rating Capacity (this is how all batts are, but include the Voltage output as well)

2) "Output Current 1000 mA" That is The Output In mAh That It Delivers U Should Have a Voltage Rating with it ie 5 volts.

If It Puts Out The 1000 mAh with 5 Volts It Will Work, Unless the Rating was Not Correct or Over Rated (frequent issue).


From What You Describe It Will Work, The 1700 mAh (and 5 Volt Output) should be Good for At Least a Few Hours to a Whole Day (can not give you an exact time, everyone vapes different.)

A larger Capacity ie 3400 mAh with 5 Volt / 1000 mAh Output will work for more then a day, again it depends how much you vape, so no one can give you an exact time, everyone vapes different.


Hope This Helps!

Keep Vapin!

Houdini, I am wondering what makes you think this?

Sorry, this is a serious question. It is incorrect and am wondering if others think this as well. There seems to be a lot of confusion about usb passthroughs and power supplies these days.

I have the Duracell battery pack and it does not work on my passthru from PS and has been tested with others from PS and did not work. But it does work with the passthru with the battery in it. I can't remember who sells that one. You saw that huge thread about it, didn't you? Yeah, you were in there, I remember. Or is this a different kind of battery pack?

[CandyGirl]

it's true. i purchased 2 of the duracell batt packs before it was discovered it wouldn't work. no joy here.

Yes, this is a different one. It was found the Duracells weren't powerful enough to power the passthroughs but the one in the OP says 1000ma output, so it should work.

Ok here's my question (here we go again). If a USB port on a computer puts out 5v. and 500mA and my e-cig passthru (with no battery) works just fine, why does it not work with a battery pack putting out 5v. 1000 mA? I'm not saying your wrong, I'm just thinking there is circuitry in these things that looks for a battery in the device its powering and if it does not see one then it shuts down.

I really don't know. I have no idea what my laptop usb current is, but I do know the passthrough works on it....but not on other 500ma devices I (and others) have tried.

My question would be the same....if people are saying the usb port is 500ma, then why does it work? Beats me...lol

We'd probably have to ask trog or something. I know absolutely nothing about batteries but have learned along the way (through trial and error) what works and what doesn't.
