About UK USB adapters

[Karma]

I've used something like this for ages with no problems at all

Thanks cHooBeyDoo, have you used these 2 sites before?

Not yet, but I definately would use them, the first one is in the list of vendors on this thread here

OneZeroNyne What people get confused about is that the bit that plugs into the wall is NOT generally the charger it is the POWER SUPPLY.

The charger for a Ego battery is this part :



This has circuitry in it to give the correct voltage and the correct charging current. It should have a little label on it that says something like 4.2v (this voltage is important) output at 500mA.

The problems have occurred when people have used the WRONG CHARGER LEAD as some will give out 5 volts.

An Apple, Samsung etc etc etc Power Supply is OK (I use a 2A rated Power Supply) PROVIDED YOU USE THE CORRECT CHARGER

Watch this video at 32 minutes and you'll see what I mean :



If it has a USB socket on the device then the charging circuitry is in the device and you can stick any USB power supply in there. The USB is the small port on the bottom left of this picture of my MVP's & iStick's are the same. See here:



To be ABSOLUTELY sure use the charger that the manufacturer recommends or ask the vendor.

Excellent post DiscoDes , I should be ok then as the charger comes in the box with the Emow mega kit .

I'm charging my MVP2 and I've got two USB chargers, a 1A and a 2A. It doesn't matter which one I plug it into it draws the same current, 0.9A.
Chargers less than 0.9A will also work with the MVP2 but will take longer to charge.

Don't worry about the size of the charger, just make sure you buy good quality equipment.

You can get one of these to monitor the current (and voltage) and see for yourself

Also useful for mobile phones, tablets etc.

Now THAT is a handy bit of kit.

There are a few similar devices on ebay but that one got a good review.

It's about having backup plan to keep safe, Ronaldo has taught me that if the charger lead fails to regulate the charge properly, it's best to have an adaptor plug that also limits input. This shouldn't be needed but on a public forum it's the most sensible advice given all the other variables we cant control.

All my wall plugs and usb leads have a joyetech logo on them, I know I am as safe as can be with proper use.

1000ma joyetech branded .... Double the 500ma

That's strange , I am sat here looking at 2 of mine and they are definitely 500mA.

They are these, - www.joyetech.co.uk/accessories/ego-cc/mains-usb-uk-adapter#.VE47T41ybIU

Not only double the 500 mA, but even more worrying is the 5.0 V part  , surely it should be regulated to 4.2 volts   ???

Thats what people are getting wrong.

A proper Ego charger will have a rated input of 5v at 500ma and a regulated output of 4.2v around 420ma or 470ma.

The wall adapter is just supplying the 5v.

Providing you have a decent Ego charger that is ce marked it will have all the circuitry inside to properly charge a battery and stop when it's charged.

The problem arises when you get some dodgy bit of kit that just uses a couple of resistors to drop the voltage a bit and does not cut off when the battery is charged.

PLEASE just look for the ce mark.

Since there is no picture of the offending device the only thing to go on is the wording, which in this case states its a usb mains charger, not a power supply.
Now, it probably is a power supply, but since it says charger, that's what I was basing my comment on.

fiddles - do you have a link to the offending item or can you say whether it is a charger or a power supply please.

Ok I am sorry if I have upset anybody, I dont mean to I just want people to be clear on how to be safe.

I take it this is the page that fiddles was quoting


Quite apart from showing the wrong picture, it is clearly a USB adapter.

As I keep saying as long as your charger and USB outlet have a ce mark you will be safe

rughead121 - there has been no offence taken and i'm definitely not upset in any way by your comments.
I hope you haven't taken offence at anything I have said either.
It's always good to have different viewpoints on a subject.
As I said, my comments were made purely on the fact that the screen shot kept using the word charger rather than power supply.
I reckon you have correctly found the offending item and it is indeed a power supply so 5 volts would be correct for the output. 


The point about the ce mark is fair enough, though that assumes it is the correct ce compliance mark and not the look-a-like ce "china export" mark that some unscrupulous people might stick on their goods to look legitimate.

At the end of the day it's up to the individual to use what they feel safe with.

Absolutely.

The dodgy ce mark is a worry however Trading standards have been quite aggressive with anybody selling these.

The one I saw really was shocking. Just a couple of wires and a couple of resistors. No protection whatsoever.

May as well pack it with gunpowder. Actually that would probably be safer

Still I do advise check for the ce mark. there are very few 'china export' deathtraps around any more.

The only other thing I will say is think about what you pay for it. If you buy a charger from a market stall for 50p or a pound do you really think you have a safe charger?
