Due to Australia's use of 240 volt 50 cycle power standard most items sourced overseas are a hassle as either UK or USA plugs are provided. With the advert of the internet a lot of suppliers from China and Hong Kong are shipping items with adaptors rather than dedicated power plugs even if you clearly state they must be compatible with Australian power points and voltage.
No issue with a high quality adapter but AW with the Ultrafire chargers are shipping an adaptor that is potentially dangerous. It can not hold the weight of the cord and plug without becoming lose and exposing part of the pins. This means with the 240 volt standard any skin contact is potentially lethal. Also in Australia due to deaths adaptors and extension cords must have enough over lap in installation that by the time the pins are exposed the circuit is broken. This is a common-sense design that is now generally accepted as an excellent idea and adds virtually nothing to the cost of the adaptor / extension lead. As mentioned the 240 volt standard means a lot more danger than the USA 110 volt standard.
The adaptor shipped is a remarkably poor piece of design and appears to be designed to handle European/UK and USA plugs. This means the grip on the very thin USA plugs is inadequate and by the the Grace of a Protector you go. Adaptors sold in Australia have a deep well that means even if a plug becomes lose you will not be exposed to the bare pins.
Electrical safety is a big issue and it is disappointing that countries and suppliers are shipping items that are potentially lethal when much safer design exist at a minor or non existent extra cost.
And this adaptor is not restricted to AW as it has cropped up a few times in ebay complaints with suppliers selling Maha chargers out of Hong Kong and most electrical items.
