Battery packs are practical but often too big and mostly forgotten? Better is a lighting cable that already has the battery built in.
Nomad offers such a Lightning cable. It’s easy to use: When charging the iPhone, connect the cable to the iPhone itself and the charger as usual. Done. The battery in the middle is automatically charged as well. This saves an external battery pack and an additional cable.
The battery isn’t very big (after all, it should look quite elegant), but for the purpose of recharging the iPhone (probably a normal size one) in an emergency once very sufficient.
We are already in the upper price range with almost 50 dollars, but for many it might be worth the money to have such a useful travel companion. In addition, the lighting cable should also be very durable.
