More of a mouse than a monkey – this kit has a compact design. But it’s very well made and when full is claimed to give 96 hours’ phone standby or 40 hours’ iPod use. It’s versatile, with adaptors for most phone brands, as well as digital cameras, iPods and even Sony PSP games consoles, plus a USB socket. Yet there was no adaptor for our mobile! Not cheap, but its large-capacity battery would make it well worth a look.
