ASMO Charger only draws power when a phone is connected

Your money saving charger

If you leave your phone charger plugged in when you're not juicing up your phone, you're wasting a lot of electricity. Not only does this cost you cash, it's also bad for the environment. Thankfully, ASMO Charger is here to help.

It's the world's first charger to only draw power when a phone is connected. You can leave it plugged in all day without worrying about harming the environment or you bank balance.

Even better, it switches off when your handset is fully charged.

In other words, it's economical, environmentally friendly and fire safe. What's not to like?

According to the manufacturers, it charges "at up to twice the speed of standard chargers" too.

It has a long cable, so you won't have to kneel on the floor to make calls while you're charging.

If your phone is too old to have the USB On-The-Go feature found in most mobiles since the iPhone 4, you'll have to press a button to start it charging. But it'll switch off automatically when charged regardless.

It comes in versions for the UK, US and EU. If you want one, pledge $35 (£23) and it'll be yours when it starts shipping in October. Company founder Asmo Saloranta was inspired after a personal tragedy – his fiancee's family home burned down because of a fire caused by a mobile charger. Hopefully this gadget can help avoid any such future occurrences.

You say it will save me a lot of electricity. How much electricity does a charger use when the phone is not connected to it? It only feels warm when the phone is connected, so it uses less electricity when the phone is not connected (when it feels cool).

a number of websites have performed such tests and shown that "vampire power draw" is between £10 and £15 per device per year...

Great, so I can plug my device in at, say, 11pm so it charges by 1am. It then stops charging and starts discharging so that by the time I wake up and unplug it at 8am, it has been draining for 7 hours...

For my phone that would usually mean it's at 80% at the time that I want it to be 100%.

...sold?

I can totally see what these kinds of gadgets are trying to do, and I'm all for stopping the cumulative "plugged in but disconnected" wastage, but NONE of them seem to realise that the entire point of charging overnight is so the device is at 100% AT THE POINT OF DISCONNECTION in the morning!!!

Congratulations on coming back I pledged for your previous campaign
just new you had to succeed with this. Please can I ask a few questions
:-

Is there a way to add the covers to the double / triple pack?

Do the covers effect the heat the unit generates whilst charging

Will the wall plug side be interchangeable so it can be used for traveling?

At least there is a business trying to do something about it and if you leave your mobile on continuous charge through the night you are ruining your battery so much more regardless.
That said most phones with built in batteries do not help because they force the phone to switch on as soon as they receive a trickle amount of juice. Although blackberry phones with built in batteries do not do this which is decent.

Not necessarily; lithium-based batteries actually last longer if they are topped up regularly and/or kept topped up. Full charge/discharge cycles cause the battery to expand and contract which causes stress damage over time. The less the battery discharges, the less stress. Li-based batteries have no significant "charge memory" so there is no problem there (source: batteryuniversity)

The only consideration is in terms of heat, but trickle-charge top-up when at 100% is negligible heat...
