Brunton Metal 4400 Electronics Charger  £49.99

8/10

Useful & reliable backup battery for charging your cycling gadgets on multiday trips

Here's an interesting widget for touring cyclists. The Brunton Metal 4400 Electronics Charger is ideal for touring or multiday events where you might not guarantee a source of electricity, but want to charge your mobile phone, GPS computer or lights.

It's very compact and not all that heavy at 208g, with a natty carbon fibre-look back plate. It's not something you're going to carry in a jersey pocket, but it'll go in your pannier or saddle bag.

Inside the tough case is a 4400mAh lithium-polymer battery, which I found was plenty to charge my smartphone a couple of times and top up my Garmin Edge 500. An iPhone 5 has a 1,440mAh battery so that gives you some idea of the charge the Brunton stores. They claim it'll charge four smartphones, and my testing showed this to be the case.

A small LCD screen serves as a power level indicator so you know when you're running low. To charge the Brunton from empty takes about four hours from a USB port. Bruton claim the battery can be charged 1000 times.

There are two leads, a micro USB - fine for my Samsung phone - and USB 2.0 lead that can be plugged into any compatible device and also used to charge the Brunton. In the top of the unit is an integrated USB port for plugging any compatible device in, your tablet, phone, MP3 player, lights or GPS. The only change I would make would be to add a mini-USB lead so I could charge my Garmin without needing the correct USB lead with me. It would be perfect then.

The Brunton is a smart and well designed reserve battery that works well, and provides plenty of juice for keeping your gadgets topped up. That's ideal if you're planning to ride over the course of a few days and don't want to let your phone or other device run flat. I've also found it handy for travelling, and given how small it is, I've taken to always stashing it in my bag when travelling, just case I need it.

Verdict

Useful & reliable backup battery for charging your cycling gadgets on multiday trips

I'd say get an Anker Astro E4 13000mAh instead - a bit heavier but 3 times more capacity and almost half the price.

I've got the older E3 (which is 10000mAh) and it's a fantastic piece of kit. Kept my lights, Garmin and phone charged on 2 24hr events last year and had

Has two regular USB slots rather than built in leads meaning means you can plug in whichever USB based leads you like - making it more versatile

Fifty quid?

How about 5600mah for £8.99?

You can buy 4, run your phone for a week with the GPS on all the time and still be in pocket.

20,000mah for £13

3 of them at £39 and you're off on a 2 week cycling holiday camping all the way and never seeing a charging point.

Anker are better built than the cheap eBay ones I posted I know a few people who swear by them. I haven't managed to kill my 5000mah eBay special that cost me a fiver at the time in over 3 years.

These are very good for the price and much better on the power.. I have just about finished with a 6000mAh after 15 montsh and bought this 9000 maH now.. Thinking about camping over the TdF weekend at Rapha Tempest and my mobile phone...

I took a Veho Pebble on a long tour last year. It could recharge my phone & iPod multiple times before needing to be recharged itself. The 5000mAH model is about £23.

Even more convenient, and much cheaper, are the ones that take 3 x normal AA batteries. Minimal weight and when the batteries are, just buy some more AA cells!
Perhaps not so environmentally friendly, but if there is no source of power, the only way.
They even come in a type that you can use to recharge rechargeable AAs!

Thought I'd stumbled onto WhatGadget? for a mo there Wink

Question has to be - why this review, here?

There's no cycling-specificness I can see - it's not waterproof, shockproof or ultralight, doesn't double as a blinky light, doesn't include any sort of mount like the Topeak does - not even a Garmin Quarterturn indent, which would be fab to see on a battery pack.

Now if someone built all of the above into a £50 battery, I'd be in like a shot.

I was told there would be Cake. Luckily there's http://TestValleyCC.org.uk

£50, ouch.

The Anker equivalent is 25% lighter, 60% cheaper, 33% more power, better-known brand, sold via amazon.
