I've always thought of them as thorough, and I wonder if someone has been a bit naughty with this fuse position. My reason for saying that is that some versions of the charger don't have a fuse there, but a live bare thin metal strip in the centre of a nylon plug a little further back. Like you I have three, and one is this version without that fuse position. That gives rise to the suspicion that perhaps that was the version submitted for testing.

This company supply many variants in the same case, so it's possible that could have happened, even accidentally maybe, the certification being taken as read for all versions. We do know other instances of somewhat cavalier Chinese approaches to standards in other areas of course, e.g. colour codes. :rolleyes:

Apologies to all, including Mandy, as I promised not to post again.

BUT I have been distance reading this thread as a visitor.

This like the Mad Hatters Tea Party.

David I agree, if anyone wants to mess with the mains electricity TWO
screws gives you complete access.

Jimmy, does your bike go any faster with the Gorganzola charger?
I am sure the guys in China would have supplied it with holes if it needed them. I feel sure that your battery has more chance (MINISCULE) of exploding/catching fire, than your originally supplied charger overheating. My own obswervations would suggest that the charger doesn't get excessively hot as supplied in a heated kitchen.

To Flecc do half of these sniping posts have any relevance/reference to Electric Bikes?

I look forward to reading about the Jimmyengland Gorgonzola lightened bike with two speedos including the Aldi variant, what a waste of £2.99 (or was it 99p?)

Congrats to the guy who passed his motorcycle test - There is still life outside of electric bicycles

Get a life guys - Its only an ELECTRICALLY POWERED BICYCLE.

SEVEN pages of SHITE about a perfectly safe charger - Without extra holes,

Finally, another apology to Mandy, as she is going to be more pissed off than you guys.

Have a nice day.

While I'm sure it's not the case here we all all know that in it's simplest form the certification process involves no more than printing a label with the appropriate logos.

Thanks for this Flecc, I have sent your comments to the factory for consideration, I will post their reply.

And regarding playing it safe, yes, better safe than sorry! ;) I am sure Jimmy is very competent and it looks OK but I have to think of my insurance and would hate to be responsible for killing off any of my wonderful customers :eek:

Best regards David
LOL! Why don't we take a look at all of the electric bike chargers out there and will probably find that each and every one of them is not perfect?
Neither are the chargers we take for granted that are within our homes and we all use on a daily basis without harm in most cases if used in accordance with there instructions?
I have absolutely no problem with my charger supplied by Wisper, I do not find it runs very hot at all and I do not use a cake rack and was merely a suggestion for circulating air around the whole of the charger box if anyone had concerns.
My laptop charger which I have used on a daily basis for three years runs far far hotter. Whilst I understand the issues with L Ion batteries having caught fire, then I would suggest that you switch the charger off at the wall before you go to bed regardless of whether it is a Wisper charger or not.
"If it ain't broke don't fix it" and I do feel some of the guys on here are being somewhat negative towards Wisper and there chargers so please gather up a few other makers chargers and do a comparison just to be fair.
Whilst I understand that we are all wanting to improve on the technical aspects of our bikes I feel we have exausted the Wisper Battery charger old and new.
Kindest Regards from a happy Wisper bike and charger owner. :D

Not so Mandy. There is no Wisper charger as such since they don't make them. Chargers are designed and made by specialist companies and used by many makes of e-bike, so we are automatically including others. For example, Wisper's new charger has been used by eZeebike on it's range for a long time.

This is an appropriate forum for this sort of technical discussion, and if you don't like the thread, just don't read it, but please don't advise others when to stop the discussion. It's for them to decide when.

I have to admit to being puzzled about the certification in relation to that fuse, I have three of those chargers and they all have the fuse in that position. I can only assume that the holes are considered small enough not to be a problem, it isn't how I would design it though..
I think it goes to show that EU certification on virtually anything is not foolproof and, in fact, it is often a compromise between many EU countries' standards which means that countries which had a higher standard sometimes have to lower theirs in order to conform to the new standard. For example, years ago, there was talk of making the UK domestic wiring conform to the rest of Europe. So our shuttered 3 pin, earthed plug sockets and plugs with insulated prongs and so on would have had to conform with the ones in France (where I was living at the time). These French plugs were 2 pin, no earth, incredibly flimsy and fragile and I regularly received shocks from several plugs in different aprtments and houses. Thank heavens, we kicked that one into touch, although all our wiring, instead of RED meaning live and black neutral, is now brown for live and blue for neutral... just to conform to the EU standard... in my opinion, a terrible move. RED means danger in most signage, does it not?

Anyone here irritated by the enormously powerful 'fireworks' sold in the UK now? Small explosives would be a better description. I've seen several postboxes blown apart by them and seen a cast-iron front of one blown across a main road. But... years ago, we didn't have fireworks like that, did we? No, just Little Demon bangers and Vocanoes etc. We were made to conform with the EU standard on fireworks several years ago, despite intense opposition from people here in the UK. We were made to accept these fireworks in order to conform to the EU standard. We've all seen thh results, I dare say.

So... no.... EU certification does not, in my opinion, mean safe, or better or more secure or indeed any value judgement whatsoever. It simply means that something conforms to an agreed standard, good or bad. Like the chargers which Flecc has pointed out.

"I would say all electrical appliances that are plugged directly into the mains should be treated with respect and anyone with any common sense will realise you do not immerse in water or get a child to place there finger into any accessable holes so that should go without saying"

If you read the post properly, it's clear that I haven't suggested that anyone get a child to put a finger in there or deliberately immerse in water. And no, it doesn't go without saying (read any electrical device instructions). What I posted is perfectly valid.... ie with a charger modified in the way that I have suggested, take extra care that it doesn't come into contact with water or is accessible by a child. Most definitely it does need saying.

By the way, this is the last time I'll be responding in any way whatsoever to any of your posts (although somehow I don't think this will be reciprocated). They add nothing to my technical knowledge or riding experience, you see. No doubt, I'll be posting more on the site, including more technical suggestions but having to re-state the obvious, be deliberately (or is it maybe not deliberate???) misunderstood about very simple things or indulging in a verbal Wimbledon over totally pointless things isn't where it's at for me. So no further responses from now on, although please do have the last word on this.
Hi James

You have obviously not read my post properly? I never said you suggested a child should put there fingers in any holes or immerse the appliance in water.
You were stating the obvious that everyone is aware of and simply reiterated it as it is obvious.

I was certainly not entertaining a "Wimbledon" thing as you state, but was just simply putting my views across as I am sure I am permitted to do together with suggestions?

I apologise if I have offended you James and I further apologise for my review of the rewiring problem on my SE in my situation. My opinion was obviously not up to scratch in your opinion after asking me of my findings? Well you certainly didn't like it but I simply tell it how it is. I fluffed it up on the forum to please you but repeatedly stated in posts and told you that I did not use the pedelc mode so made no difference to me due to my back problem.

written by James: "They add nothing to my technical knowledge or riding experience" Sorry James, but you are a little up your own bottom but probably a thoroughly nice guy underneath it all :D

Happy biking and Happy tinkering :D

Spellings???

Go back to your motor bike forum :mad: :mad:

Hi Flecc
Okay then, the chargers supplied by Wisper :( Nobody has mentioned other manufacturers using these chargers as far as I can see and this does all seem to be about the Wisper chargers and that was simply my point.

As we know, most subjects have a natural life-span anyway until something new pops up, so individual members calling 'time' on a thread is not required, desirable or acceptable. On some threads, if I've read enough and think that that's enough, I just stop reading them. I wouldn't dream of telling others to stop talking about it just because I've had enough of it.

Product forums (or is it 'fora'??) are used by hundreds of manufacturers for product and service improvements. They welcome criticism as a form of free product development advice. Thrashing out product issues ad nauseam is very productive and it is often at the last gasp of such discussions that innovations are made. Let's keep it up!

This kind of behaviour is unacceptable. The site was established to provide a friendly forum for electric bike owners to congregate, please respect the forum rules.

You surprise me! It's been mentioned many times including in this thread, first by John here,

then by me very explicitly here.
