OTGP 18650 USB Phone Charger Promotion (Extended)

Due to Hurricane Sandy affecting customers on the East Coast, United States, this promotion will be extended until November 7, 2012 1:00 AM U.S. Eastern Time.

For a limited time, the standard edition of the 18650 USB Phone Charger will include nine batteries instead of three.


Batteries may arrive in an alternate battery container instead of the battery box featured with the product.

Did you receive the OTGP 18650 USB Charger Preview/Trial Edition?

Yes, it's completely free and you'll never be charged for it.

Many people aren't aware that a mobile charger with replaceable lithium batteries exist. We're attempting to send them to customers in each U.S. State; we can no longer ship them internationally due to recently-imposed lithium battery shipping restrictions. Otherwise, the entire planet would receive them; hopefully, this will change when its successor is made available to the public.

So why is a solar company providing traditionally-powered devices to its customers?

Lithium Battery Shipping Restrictions

Recently, the United States Postal Service (USPS) has placed limitations on the shipment of lithium batteries outside of the United States....well it's more like a prohibition: we simply can't.

Many of our customers are located outside of the United States and while we don't mind offering free shipping for everyone, $80.00 to ship our lithium charging systems with other carriers isn't something that's possible.

Mobile 18650 USB Phone Charger: Version 1.1 Update

The Mobile 18650 USB Phone Charger's hardware was slightly modified to accommodate a problem I've noticed with mobile devices (not the charger); some, such as "wireless hotspots," require customers to buy expensive charge-only cables because they won't charge when connected to a computer. Some mobile devices also refuse to charge unless its origin power is Alternating Current (AC), or plugged into an electrical socket.
