This thing is great instead of always looking for a plug. Sure it might seem bulky, but if you’re traveling you can have it in your bag. If you tend to carry a purse or backpack, just keep it in there. The benefit of this over just plugging your phone into your laptop is that you won’t also drain your laptop battery faster, or perhaps you may not even have your laptop with you. Fairly cheap and useful. Especially if you use your iPhone a lot (can’t change the battery like other phones).
