"No more bulky external batteries or tangled wires connected to wall mount chargers? Sounds like a deal to me." - Travel Pulse  

"Smartphone external batteries come in a variety of styles, but the Power Annex might be one of the better designs out there. " -Trendhunter

Risks and challenges

After months of prototyping and designing the Power Annex, we pushed the limits of maximizing the battery capacity within a slim profile. Ultimately, it was a major challenge to keep the Power Annex under .4 inches.

Forecasting time for tooling and for certification was a challenge. After exchanging dozens of emails with our manufacturer, we established a well defined timeline to focus on holiday delivery!
