The question is... Which failed first.

I too got "stinky fish" from the title.

2019-06-22 03:15:42 +0000 UTCExcellent, more reviews and tear-downs of exploderized electronics please!
2019-06-21 03:05:50 +0000 UTCJust buy a branded unit from a prominent high street name. That could include IKEA, ASDA and many others that need to protect their brand's reputation.

2019-06-20 19:22:27 +0000 UTCMy current preference is an IKEA charger, but any unit bought directly from a prominent brand will have to be compliant to protect that brand's reputation. Even ASDA or Walmart are options since they need to protect their name.

2019-06-20 19:16:07 +0000 UTCSo what is a decent power supply? I use the Apple 1 amp cube and Apple 2.4 amp units and the IKEA Koppola 3 port 3400 mA chargers. They all seem to run cool.
2019-06-20 18:44:56 +0000 UTCA Little different from your usual fare, but would you consider doing a design and build of your own USB (or generic/multi voltage) power supply and/or "dream" lithium Power pack? I'd like to see what a pro would come up with designing something useful from scratch.

2019-06-20 15:02:53 +0000 UTCSome of those cheap USB supplies terrify me. Probably why I hang on to every Apple phone charger I've ever owned, because Apple would never risk your life, they want you alive to buy More Stuff

2019-06-20 13:26:44 +0000 UTCI grew up thinking that Trading Standards et al (in the UK) were going to protect me from such products. How naive. Obviously my posty doesn't call in to their offices before delivering my Far Eastern purchases! That phone case going live is new to me and very disturbing. I do have one of those plastic covers - how good am I - but I can tell you that the floor below Ely Cathedral's (amazing) lantern hasn't got the message. Surprisingly I was able to continue snapping away despite the broken screen. So, BigClive - how can we tell that a particular charging device is safe? (Other than looking for melting plastic). Thanks for another eye-opener BTW.
