GoPong's Power Bank Flask looks like a regular portable charger so you can fill it with your favorite drink and take it to virtually any indoor or outdoor event. The unassuming bottle design even includes a fake power cord so you won't draw any attention from security, which makes them great for taking anywhere. We do not condone any illegal uses, but like you, we hate overpaying for drinks! So the flask holds 8 oz and can easily be filled using the included funnel and liquor bottle pour spout to take on the go. The screw cap provides an air tight seal to prevent any leaking of liquid or odors. Once you are ready to drink, simply unscrew the cap and mix with your favorite beverage. The flask will pay for itself after one use, so get yours today! Please remember to always obey all local drinking laws.
