ZeroLemon is a known brand for their after market battery, so I decided to try out this charger Make sure your phone support Qualcomm Quick Charge, otherwise this won't give any benefit over regular charger.
First look: - The unit comes in a plastic package, a small recyclable cardboard box should be nice. - USB cable included, which is a plus.
Appearance: - Very generic brick style charger - The prong plug is removable, to accommodate different region plugs. However, the prong is not foldable. - USB cable is quite stiff Performance: This is where the fun begins. I test this charger with 2 different Quick Charge compatible chargers. Using Nexus 6 and HTC M9. I let the phone drain down to 5% battery and start charging. record with every 10 minutes Minute - Moto Charger - HTC Charger - ZeroLemon Charger 10 - 15% - 14% - 15% 20 - 26% - 24% - 24% 30 - 39% - 38% - 37% From the result above, this unit is comparable to OEM chargers that comes with the phone. I notice that this charger runs warmer than other two, but not really a big issue. For $20, this charger is $5-10 lower than other brands. If you need a charger that serve as backup or travel use, this is worth buying.
