Every time we want to get one of these type of offers, our local Tesco tell us that they're not on the system so can't sell us them.

thats cos its asda

thats cos its asda



LOL!

On a more serious note has anyone used one of these (or similar) before. I am heading away camping and this seems like a good investment to charge my Asus Netbook and other stuff I don't have in car chargers for.

The netbook should be well within the wattage range of this but how much do they drain the battery and can you use them with the car in motion? (I presume you can).

They can be used whilst in motion. This one is pretty low powered but a good price. When looking at these they often quote an inflated wattage (peak) as it sounds more impressive than the important continuous figure. I have a 300w cont (600 peak) and it runs all sorts in the van or truck.

Ah ok thanks for the reply.

I might take a look at it as the Asus only has a 40w adapter anyway. I'm more concerned at draining the car battery whilst we are away even if I mainly use it when we are actually driving.

A decent inverter should have a low voltage sensor that shuts it off when the battery reaches a critical level...not sure about this one though.

As I put on the MSE one with 120w, I'd be very surprised if you can run the Asus on 80w..... it may well say 40w, but that's the output. Generally, when you step down the voltage, there's quite a lot of inefficiency. My Lenovo one makes my 300w (peak) one scream when I first turn it on and yet it's only marked at 90w on the PSU.

Have some heat, and rep if admin haven't changed all that!!!

i have used one of these before and works fine with most things but not laptops/netbooks as they switch from on and off which can ruin your battery. i found it better to buy a in car adapter for mine. hope this helps

Still £15 in Slough ASDA.

Ooops, guess I didn't read it properly

I picked-up this one last week for then same reason.

I haven't used it yet, and dont know a great deal about them, but the extra replies to the post, may point you in the right direction.

$5 is by far the cheapest I've seen, after looking around last week, so heat added

Good deal, heat added.

i ordered one of these just this morning from dealextreme...reckon i'll still see if i can get one in my local asda...heat and rep.

Just bught one from ASDA in Milton Keynes. Its the box they are in that has the £5 price. The item comes up as £15. They had to sell it to me for £5 because it is their error

Thanks, just what I needed

This may have died, a friend went to get one and now is £15 (the box with £5 on had gone too)

still £15 in Asda Wakefield. They weren't in the box with a £5 label

Just been to Owlcotes Pudsey Asda they are £15 not in the reduced box. Must be store specific where did you get this one from?

But by the time it's reached a critical level, it won't start your car.

You were lucky - they could have refused to sell it to you at all. What they couldn't have done is forced you to buy it for £15.

The ones with the low voltage sensor should shut it off if your battery reaches 50% (which is actually quite critical - you shouldn't let your car battery go below 50% at any time)

There is not that much inefficiency - 10W at absolute max. That inefficiency is turned into heat, and 10W from a power brick would make it extremely hot.

By the time it hits LVD, it's too late. All you'll get from your car is click click click

The tesco 120W one I posted http://www.hotukdeals.com/deals/ring-compact-120w-power-inverter-su/708481?page=4

is a better item and i confirm it works with my MSI wind netbook. Its 120W peak power not sure why, as it can only put out 120W for 5 minutes but 100W is the standard current which it can put out for 4 hours. Works fine in my experience, just use your head and youll be fine with regards to flattening your bat. But if anyone is abit worried about just having 120w then get the 150w ring power inverter which can be found on ebay/internet for £25-£30. It probably has a peak of 150w and normal rate of 130w.



Yes you can get those 300W, 400w, 500w etc but dont most of them if not all have to be connected direct to the battery?, i think they do. And they are a different item really with a different use. These small ones are designed for incar charging of small appliances such as netbooks and mobile phones. The ring one is even shaped like a can so that it fits in your cup holder. Those big square high watt ones are designed for powering tools, lights etc and not really comparable.

Just picked one up at the York store. £5 and they had about a dozen left.

Still £15 in my local store...

HA HA HA HA HA HA HA HA HA HA

They were still £15 at Asda in Basingstoke, no ticket saying £5 on shelf and got them to scan it to make sure, thanks for the post tho, I will keep an eye and see if they reduce them

so will it run a lappy and a netbook or not?

still a dif in price lol

has anyone tried leeds stores?

You think they would've done a spellcheck before making the boxes...what is adjustble?!

Still labelled £15 at Wakefield

Went in again today to the Basingstoke store and they were officially reduced to £5 on the shelf ticket from £15 so may be worth everyone checking again now!

Asda derby was £20 now £5, loads left last night in a basket near the dvd counter
