The Fenix ARB-L18-3500U USB rechargeable lithium-ion battery has a built-in USB port and can also be charged using an external charger. It offers an extra level of protection with an anode circuit encased in a steel housing, and as the battery is fully wrapped in steel, the risk of short-circuiting due to impact or collision is drastically reduced. 

Note: This item is packaged and priced as one unit - one battery. 

Shipping Note: Lithium ion batteries are considered "dangerous goods" per US transportation regulations and can often only be transported via ground shipment. Orders containing loose batteries will typically take much longer than predicted to be delivered. Delivery times of 14+ days are not uncommon.
