can only supply up to 10W of power, but if you need a basic charging stand for juicing your phone overnight, it’s currently down to just $13.58 (about $6 off) at Amazon , nearly matching its all-time low. The Qi-certified charger can prop up your phone in either portrait or landscape — it can even activate Apple’s handy StandBy mode — so you can easily see notifications as they come in. The 313’s charging speeds are significantly slower than those offered by more modern options equipped with Qi2, but it’s still a solid choice if you own a smartphone that’s a few years old.
