1. Veho 360
There are no unsightly wires with these well-pitched four-hour battery speakers from Veho. The 360 uses Bluetooth to connect to your mobile, iPad or iPod from up to 15m.
The wireless Jambox may be on the heavy side, weighing in at 327g, but it certainly packs some punch, giving 85 decibels sound with more than eight hours of battery life.
3. Altec Lansing
The advantage here is size? it's small enough to fit into your pocket or purse. And as it has the same driver as Altec's standard speakers, it has a surprisingly oomphy bass.
4. Horn Stand
Escape the tyranny of flat-speaker batteries with the Horn Stand, which amplifies your tunes by 13 decibels, magnifying your iPhone speaker physically, rather than electronically.
5. Rubik's Cube
This USB number may only have 3.5-watt speakers, but what it lacks in power it more than makes up for in 1980s retro chic. Play your Duran Duran albums in style.
Unusually for a portable iPod or iPhone speaker, the battery-powered iHome actually charges your device as it plays. Plus its outer casing is water-resistant.
7. XMI X-Mini Max
It's no good having a great-looking speakers if they can't survive being bumped about on a long-haul flight. These battery-powered speakers screw together as a sturdy capsule.
8. Dual Cylinder
Avoid the tinny, 'bee-in-a-jam-jar' quality you often find with speakers at the lower end of the market with this pair of bassy, three-hour battery speakers.
It may only be five inches long but the Soundtraveller offers a deep bass and 6 watts of power. And as the Bluetooth device runs on AA batteries, it has a 12-hour play life.
10. Sony SRS-M50
Sony's 5-watt offering has a fairly rich bass and impressive vocal listening, as well as a built-in magnetic shield to prevent interference from other electrical equipment.
