All Powerbanks are not created equal.
Most powerbanks you have to spend more than half of the day recharging. The ones that claim to be a quick or fast recharger, still take 4-6 hours to go from drained to fully charged. Not Yukuma. Our patented technology allows our power bank to fully charge in ONLY THIRTY MINUTES! We dare you to find one of the big external battery companies on Amazon who has anything close to us.
Our LED light status will show you how much charge the battery has left so you do not have to guess. Here are some of our technical specs:
Capacity: 3.7V/10000mAh 37W/h Input: 13.2V 5.6A Output 5V/2A 9V/1.66A

Is it safe?

1. Smart system of fast charging identification.
2. Electrostatic protection
3. Short circuit protection
4. Temperature deviation protection
5. Software malfunction and hardware short protection
6. Input overcurrent and overcharge protection
