Today, we can no longer imagine life without electricity. But sometimes we find ourselves in a place where the electricity grid does not reach, so we have to find our way. Long gone are the days when fire was the only choice. Today, we can create our own mini-network, which supplies us with much-needed light bypassing electrical suppliers. One such is the BioLite NanoGrid portable USB system, which provides the necessary lighting while also serving as a charger for other USB devices.
