Review on SZDASZ Motorcycle Waterproof Backpack Magnetic by Michael Robertson

Magnets definitely need to be stronger, bought this to provide an uninterrupted charge for a 450+ mile ride. Thank goodness I used a belt otherwise I would have lost it all, once you hit 60mph it will hit or miss if it comes loose. Apart from being a great and useful item for travel I didn't find the right size magnet as you can remove it but hopefully the company will consider testing and fixing this for future customers.
