My new favourite tech gadget: a battery

It’s a battery:

Not much to look at you might think. But this spare Huawei HB4F1 battery remedies the one drawback of my previous favourite tech gadget – the superb 3 MiFi hotspot.

The combination of Three’s network reach and reliability (at least in areas I frequent), the HSDPA speed (faster than GPRS) and its ability to network more than one device at once, meaning you need pay for only the one contract, would have made the 3 Huawei MiFi a favourite even if it hadn’t also been small and light. Its one flaw is a short-ish battery life, measured in hours but meaning that a full day out and about sees the battery die before the day ends.

But now that I’m armed with a spare battery for it, things are even better.

The more alcohol-minded might be more interested in this corkscrew.
