The built-in LED makes the battery a little unwieldy flashlight, yet convenient. I do not want to miss this accessory.
Only a small flaw is the battery: if it finds no charge, the battery switches off. Unfortunately, I have some small appliances, draw so little power that then the battery shuts down prematurely, before the device is fully charged. I can indeed deal, as I have a second unit load in parallel, however, I would find a function good, with which I can say the battery, it should remain continuously in order to invite even those small devices reliably.
Nevertheless, we have converted all battery's to anchor devices of friends. Price and performance are good, even the warranty processing - should be what times - is reliable and easy.
