I.have actually (I remembered this! lol) a pack of waterproof phone bags.
Also today, I applied for the power iq usb car charger. If I'm successful, I'll give to my step daughter n her wife, who is due to pop (give birth) very soon. They can have this in the car to not only recharge handsets, but also power any car items for baby.
I know already, it's one of (top 5 at least) the top at doing its job. Even tho they haven't all singing phones, it'll mean a small journey will give their fines a big charge. But it's also powerful enough to power anything they might use for baby.
