Risks and challenges

LITHIUM ION SAFETY:
In light of recent controversies around lithium ion batteries, product safety is a top priority. Power Mountain is UL 2056 tested and compliant, protecting you and the devices connected to the power bank. FCC, CE, IEC60950, RoHS and UN38.3 safety certifications will be completed to provide assurance.

SHIPPING:
Due to additional safety procedures, there are high costs for air shipments containing lithium ion batteries. We have identified a specialized logistics provider to assist us in getting these power banks to your homes as soon as possible.
