This solves a long term problem I have had with international gadgets coming with 2 prong plugs and a cheap AU adapter. I often have to use adapter plugs to power up gadgets from overseas. I love that this product has 3 x USB charging ports and 3 x standard AU power plug ports (with earth) that double as 3 x International plug ports. I can now plug my aftermarket satellite tuner which has the 2 prong International power plug directly into the power board (without an adapter) and it is stable and not wobbly (unlike the cheap AU adapters that come with some gadgets). I've also been able to clean up and consolidate other wireless charging devices all in one place using the direct USB inputs to charge up quickly. I really like the dual AU/International plug ports - a good innovation.
