Good, cheaper, lighter battery with weaknesses in mobile use

Simultaneous loading and unloading is not possible with this device. This was previously known to me.

I'll be as far along well with shaking LED display. I like the finer gradation (10 LED step towards the common 4 stage other batteries). The Schüttelsensor works only along one axis. If you simply put the battery according to a pocket, then vibrations while cycling does not necessarily lead to the fact that the LEDs light up all the time.

1 star devaluation there is that the battery does not really with my wants tolerated "mobile" power generators:
At the solar panel and the bicycle dynamo charger the battery loads like to not complete. Sometimes the LEDs but full of juice; after a brief discharge of the charge level then suddenly jumps back by several steps.
Also, it seems that at charge currents below 500mA charging not "really" works. The LED then begins to flicker. And, although only 50 mA are specified by the manufacturer as a minimum current.
Furthermore, are not used by the maximum battery charging current of the generator, but loaded with just about 500mA. Only at the outlet, the battery seems to load faster.

My guess: the battery is not well with fluctuating load currents. Monday Model? Outlet Diva? In my opinion and my purpose according to needs especially in mobile use, such as solar battery work well with loaders.

1 star devaluation there furthermore that with so far no smartphone or tablet (have devices from HTC, Trekstor, Kindle, Samsung, Sony tried) the maximum charging current could be achieved. The supplied cable appears to be a normal data cable - most, if not all, devices then regulate the charging current at 500mA from. Nix with fast charging with 2A! At least not without dedicated tinkering or device-specific cables optimization?
Clear: most other battery manufacturers are likely in this respect no better / honest work. Nevertheless 1 star deduction for marketing half-truths!
