With this powerful power bank you can say goodbye to weak and bulky extra batteries with limited compatibility.
Whether you are travelling on the go or just need a bit of energy.
Charge all your mobile devices with 4smarts‘ most powerful, versatile, fast, safe and durable powerbank.
Fast: Thanks to revolutionary Graphene battery technology, which is also used in Elon Musk’s Teslas, the VoltHub Graphene is our fastest charging power bank. It completely refills a 16000mAh battery within 45 minutes. The Powerbank itself can be fully charged in a little more than an hour, when using a powerful wall charger.
All at once: With 100 watts of power output, three USB ports, and Qi, the VoltHub Graphene lets you charge up to four devices at once, whether it’s a MacBook Pro, iPad, GoPro, Bluetooth speakers, Nintendo Switch, and more.
Safe: The use of Graphene technology enables rapid charging with low temperature development. That makes it safer than conventional lithium power banks.
Durable: The battery of the VoltHub Graphene lasts up to 4 times longer than conventional batteries. Even after 5 years of daily use, the battery behaves, as if it were new.
Travel-ready: With a battery capacity of 20,000 mAh, the VoltHub Graphene is also suitable for air travel. Take twice the battery life for your Macbook Pro or 5 times the power for your iPhone 11 with you, so you’ll always be reachable on the go.
