I write this review a few days after the Spain and Portugal electricity blackouts, this showed how reliant our societies are on electric power. The blackouts, perhaps the worst in recent memory in some places lasted up to 23 hours. One of the biggest sale items at the time being portable power banks as people were desperate to keep small electronic devices powered.
However, even these small power banks only have around 10,000mAh and can only power devices that often use a form of USB charging. This leaves anything running on 240v mains electricity often without power such as fridges and freezers.
