Super equipment. Great dimensions. Works perfectly with xiaomi mi mix 4. Fast shipping well packaged.
Amazing quality, same level as Apple products. But unfortunately the battery capacity is not the best. Is the consequence of the super compact size.
I am very impressed by this battery pack. I have a far more expensive one from Anker. But this Kuulaa is 0.3cm thinner and 15g lighter. Anker gives me 63% extra battery for iPhone 15 Pro in 2 hours 40 minutes. Kuulaa give 60% extra battery in 3 hours. So basically the same amount charge in roughly the same time, for a lot less money, in a lot thinner/lighter battery. Highly recommend this battery
