Speaking shaft:
My very large battery of Samsung Note 2 -> 7.5 x 0.5 x 5.5 cm fit in easily. Alternatively, the battery can also be clamped vertically. The extract is 2-stage, which is not in the manual. And when clamping the oval knob of the drawer should be pressed otherwise it crunches ugly in the device.
Adjusting to various batteries is not a problem for normal motor skills.
Small drawback:
Round cells can be loaded only in pairs. The contacts are somewhat "capricious". There is a danger that the round cells slip out during charging when the charger is moved.
Tip: If the loading process after you have correctly inserted battery does not function, power supply plug pulling and plugging it back in after a few seconds. Has always helped. Werden.- A deeply discharged Altakku (Li-On) was so revived)
Quality for the price is OK
The digital display is useful.
Have found my ideal travel and secondary loader.
