Don’t get fooled into thinking this will replace your traditional charger though - it’s an emergency solution and you’d need to turn the handle for three minutes just to get a minute of talk time, and for a minute of browsing you’d need to nearly double that effort with a five minute turn of the handle.
Good news is that you can also use a standard outlet to have it charged up to full capacity which is 4,000mAh battery in advance. That’s approximately two charges of a modern smartphone.
The Sony CP-A2LAKS USB charger is hitting Japan only on June 20th for a price of around $100 (8,000 Yen).
