Practically-compact backup power

The Look:
A small but very useful product if just is not a real outlet within reach. Its size corresponds to about advertising description, ie credit card size, but thicker lot, so it rather fits into the Jackenbrust- because wallet. Had me sorely surprised if it would actually have exactly the same dimensions of said map - how and where would they should attach the Micro-USB port ?!
The optical qualities are rather inconspicuous nature. Rectangular shape with rounded edge is, roughened, matt plastic housing. The Power LED acts tiny lights widerum in charging state sufficiently bright. Overall, no award suspicious design, but something you would not expect at a Power Bank anyway.

The Practice:
It was tested on my smartphone wife (Wiko Cink Slim), on my tablet (Asus Fonepad ME175CG, 7 ") and the old TomTom One All equipment was used up to almost 0% with the following results..:
The Xoro MPB 250 could fully charge both the smartphone and the Navigerät, the tablet after all, to just over 45% (which is probably related to its built-in battery of 5000 mAh). Sure, other mobile batteries provide more, but again cost a little more. So who owns electronic companion with up to 3000 mAh capacity, should get along well with this 250cc variant. If not, Xoro has stronger energy donor on the go, but to be expected with appropriate sizes growing and final prices.

The Weaknesses:
So very compact dimensions and its usefulness dropped, it falls but 2-3 small weaknesses at this Power Bank on:
1. His time has come charging unreasonably long. 4 1/2 hours it takes to the garish-red LED on went in a friendly blue. Pretty intense, I feel satisfied because the aforementioned smartphone, tablet and Navi with 3 hours (or even less).
2. The attached charging cable has a length arg scarce. This forces the connected devices over-pair to the more or less accidental "cozies".
Is 3. What not mentioned in the article description is the fact that already with the charger cable required for charging the Power Bank (each with a micro / standard USB end) should be provided together with plug head of its own budget, because that's what this is Xoro MPB 250 not included. Estimate the manufacturer simply assume that every smartphone / tablet owners has such already, so they could be even correct. Finally, the Micro-USB port is a general standard of today's mobile gadgets.

Conclusion:
Kept pretty small, apply very useful and foolproof. Despite criticism mentioned points is not a bad thing that some more hours of smartphones, tablets or whatever secures an emergency. The price-performance ratio is right in my opinion.
