Battery life on the Acer Iconia Tab A510 is great, thanks to the 9,800mAh that it's packing.

This may not match the 12,000mAh power pack of the latest iPad, but it blows the 7,000mAh of the Asus Transformer Prime out of the water and, in our stress test, also outshone the Asus Transformer Pad 300's battery too.

Acer is stating a video playback life-span of around 12 hours and we're not going to argue with that.

We got a solid 10 hours of general usage out of the A510, including streaming, gaming and browsing – with the brightness turned right up.

In our test, which involves streaming HD video with all the settings cranked up to the max, it managed an impressive 444 minutes, almost 7.5 hours of solid action.

However, there is a downside to all this battery power.

The Iconia Tab A510 takes an age to fully charge – we're talking 10-12 hours.

And don't expect to have any fun with it during the initial hour or so when charging from dead – it won't respond until it's at least 20 per cent full.

When it came to gathering benchmarking scores the Acer Iconia Tab A510 really showed its clout.

It outshone its similarly priced Tegra 3 rival – the Asus Transformer Pad 300 – and came pretty close to matching Asus' top dog in the market right now, the Transformer Prime.
