You'll have previously seen my [Only Registered and Activated Users Can See Links. Click Here To Register...], an accessory which seems to have pleased everyone - it's even won awards! In short, it was the complete mobile power solution, with enough juice to recharge a power hungry Nokia N95 at least twice. (Please read this review first, it will give you a good idea of all the typical ways to use this genre of product.)

Well.... this is its kid brother, the Mobile Survival Kit Micro. This time round, I wasn't sent the full International power and car adaptor kits as well, but these can be bought separately from the Proporta web site if needed. In the box is the MSK Micro itself, a discreet and slimline iPod-sized unit finished in matt black rubberised plastic. The case seemed a little more fragile than the larger white original, possibly due to the slightly concave top and bottom surfaces.
The main functional differences between the two chargers are that the MSK Micro has half the capacity, at 1700mAh (compared to 3400mAh), the obvious trade off for size and weight, and that there's now a Knight Rider-style animated LED curve that lights up when charging and when giving charge. In the latter case, the number of LEDs lit (out of 5) show how much charge is left in the device.
So to testing. As with its bigger sibling, you simply plug the MSK Micro into any USB port on a desktop or laptop and it charges over the course of 3 or 4 hours. It's not a fast charge, but then the idea is that you're not doing this on a daily basis. It's meant for getting you out of scrapes and it makes sense to charge it and leave it in your briefcase or pocket. The charge is held fairly well, but in the MSK Micro's case there does seem to be some leakage and I'd recommend a weekly top-up.

Then, when a phone needs charging, you just plug in one of the supplied USB leads and tips, depending on your model of phone. The MSK Micro comes with new style Nokia and Sony Ericsson charging tips, but you can also get any one other of your choice from the Proporta web site when you order - a good and sensible system. As with the original kit, I'd recommend paying a little extra for the mains and/or 12V USB adapters, to give you even more ways of recharging the MSK Micro itself.
A press on the charge button and current starts flowing into your smartphone, with charge times not too dissimilar to those from a mains charger. As mentioned earlier, the LEDs indicate the amount of charge left, although the guage seems a bit quirky and doesn't decrease perfectly smoothly.

The 1700mAh capacity, as with the original model's 3400mAh, doesn't all translate into useable charge. The laws of physics come into play and there are some losses in the electronics which manifest themselves as heat in the MSK Micro and phone battery, but I'd estimate that you can easily fully charge a 1200mAh N95 8GB battery with a little to spare. Or, putting it into further perspective, you could almost fully charge an E90 from scratch or charge a heavily used N73 roughly twice.
Given the two accessories, I'd always go for the larger, white 3400mAh model, for obvious reasons. But for anyone travelling light, or who is planning to take this type of accessory in their pocket permanently, the smaller size and lighter weight of the Mobile Survival Kit Micro will be quite attractive. My only worry would be longevity, with the MSK Micro not possessing the bulletproof case of the original.
Still, another hit for Proporta and a valuable 'get you home and beyond' accessory.
