Making battery chargers safer

[womble]

As well as my ecig one, I also have another couple of chargers that I use all the time.

I was thinking of getting a multiway extension lead, individually switched, so I can just switch the one I want on, instead of them all being on and I wondered if it's worth getting a surge and spike protected one? I'm not sure if it will do anything.

Or maybe an RCD one, but I can't find an individually switched RCD one.

Is this a waste of time?

An RCD protected one is not required. The Battery chargers should be double insulated so the RCD is pointless as you are unlikey to ever get a short to ground or you touch a live part.
A surge protection extension lead may help give additional protection but again the charger should be designed to cope with surges under the LV directives for mains powered equipment but then we are talking mostly chinese imported products here so throw any directives and safety approvals out the window. So yes surge protection does no harm.
The main thing is to buy the well known chargers which are reputed to be good and not any old chinese generic rubbish which is not a well known brand. e.g. buy Nitecore, Xtar etc.
Even the so called good ones if you open them up have safety concerns sometimes but are not as bad as the cheapies. Similarly only use quality batteries and dispose of them when the performance starts to reduce noticeably or any other abnormal signs.

Thanks, all my chargers are very good ones, I was just thinking before I bought.

In a previous post mentioned that my cheap nasty Chinese charger has given up the ghost ... Well after a bit o fiddling out of desperation to get my Vamo going its started working ... Sort of ...
Now only one bay works but it charges and keeps charging ... The red light stays on and the battery gets very hot ... I'm sure if left un-attended it would burst into flames or explode .... I tested it under constant supervision and turned it off when it got very hot ... The little 18350 battery was reading 4.2v on the Vamo.. They really shouldn't be allowed to sell this kind of crap...
