On the negative side we have the cable once. Although it is an arsenal of different adapters that should work for many devices but unfortunately the quality is here sacrificed for quantity. I use the adapter of course when I'm traveling. But he is there, it has no outlet but you sometimes need more power. Problem is that the cable is very fragile. If I throw my phone with the battery together in the backpack it often happens that the cable looses contact and afterwards you take the phone out and it is still empty. It is very annoying to have to always check whether the mobile phone now loads or not.
But the worst part of the thing is the flashlight. The knob is attached stupid or can trigger much too simple. Meanwhile, I've found a good way to store the battery pack, but I do not know how many times I've opened my backpack and was blinded by the light, because the torch is kindled again. This is especially annoying when afterwards no longer enough power plan is to charge the phone. Happens to me still now and then, because you just can not quite prevent.
The cable can be exchanged for happiness and the flashlight you have to stop to watch, so 3 stars. I would probably not buy the battery me again, even if he has a good price-performance ratio.
