Product features

  • 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.
  • Universal, super-fast charging: With 160 watts of power, three USB ports, and Qi, the VoltHub Graphene lets you charge up to four devices at once at high speed, whether it's a MacBook Pro, iPad, GoPro, Bluetooth speakers, Nintendo Switch and more.
  • Temperature management: The innovative composite batteries use graphene. As a result, heat and electricity are particularly well conducted. In comparison to conventional lithium-ion batteries, more power can be supplied during the charging process but the temperature remains stable at around 60 degrees Celsius. This allows your VoltHub Graphene batteries to go through up to 2,000 charge cycles before they lose capacity. The safety of the device during fast charge is increased and the lifetime of your smartphone battery is extended.
  • 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.
