The top one is the charger for the free Zuk power bank when I purchased the Z1. The bottom one is the charger that came with the Z1. Will the top one work equally or better than the original Z1 charger?
Right. I can leave the other charger at home and use the Zuk charger for both phone and power bank. Pointless carrying around 2 chargers.The Zuk charger is the best option for now coz it has 2.5A of O/P voltage which can charge faster.
