I bought 5 in order to use them daily, 2 of them and sometimes 4. Upon receiving them, one was already broken - it wouldn't charge anything, regardless of the outlet or cable I used. The other 4 were fine, so I didn't make a big deal out of it. Yesterday, while charging my phone with one of the daily ones after 3.5 months of use, after 15 minutes of charging, my phone started to glitch - presumably due to overheating, and the charger burned out. To evaluate it, I tried to charge again today, but now it's useless.

In one word, dangerous.

I have been using this charger to power Xiaomi network cameras for some years now and I have had absolutely no issues.

Perfect! Especially considering the price, it is the best of its kind! It charges the phone very quickly, with the only negative being that sometimes it gets a little warmer. Otherwise, very good!
