Binocktails Bev-Bank Hidden Power Bank Flask - Holds approximately 8 oz. (235 ml)

 This is the saddest excuse for a beverage container I’ve seen. Like other reviewers said, the flask leaks...badly. The two pieces of the flask aren’t fixed together well, so the water just drips from the bottom at the seam. You can see how badly the “flask” is put together when I squeeze ur (see video review).

I love this thing! We have had it for about 3 months, and probably used it about 6-7 times to get booze into different venues. We've gotten this into clubs with bouncers and music festivals with metal detectors and dedicated bag checkers. It fits perfectly into a bag or a male back pocket, and weighs about as much as a bank its size should when filled up completely. It holds about 8 shots, which should be enough to bolster a night of partying.Other reviewers have said this flask leaks, and I do see how that might happen. The flask is made of two shells glued or melted together. The seam on the bottom of our flask looks like it may be weak or unsealed, but it has not leaked once even when full and compressed!You can probably just fill this thing up and leave it in a bag, but to be absolutely sure you get in with it, do one or all of the following things:1) Fill to the brim, then slightly compress until your liquor comes out the top as you screw on the lid. This way there are no air bubbles.2) Buy/find a short little USB to phone plug charging cable, and plug that into the USB cap. THe more you can make it look like an actual bank, the better.3) I am a guy, so as guilty as it makes me feel, I give this to my girlfriend to hold with her phone while we get patted down. On the off chance they do decide to check her, seeing the phone actually plugged into the bank makes them not want to even touch it during a search.Once inside, pop off the top grey part, throw in a back pocket or purse for easy access, and have fun!

The concept was pretty cool and I was really excited to receive the product, but when I tested it out... The product was not glued together properly and liquid leaked out the bottom.

I've been to events of different venues and sizes ranging from: festival, rave, concert, boat-party, and many more.First of all, no security guard has ever even bothered to check this. What I do is bring a broken charging cable and actually connect it to the USB slot of this flask. Make sure to hold it on your hand connected to your phone while you are at the security. They automatically assume this is a battery charger and let you through. Honestly, you can probably fit 6-8 shots worth of liquor maybe even more.

BEST THING OUT! Security at the event did not even consider that this could have alcohol inside. Highly recommended!!! Just make sure you fill it to the top so there is no empty space before going thru security.

Awesome! Got it in all three days of the festival. Security did not think twice when they saw it. Saved me so much money!!

I’ve seen other reviews say that theirs leaks, I guess they got a bad one and should have them send a new one. Mine works great and I always have it in my backpack for when I need a good buzz. The port was difficult to fit a usb charger at first, but after some effort was able to fit a cheap charger into it

Bought this item & even though it was a little leaky from a defected cap, it worked perfectly as long as it stayed upright. Worked like a charm & received so many compliments/questions on where I got it. The sellers were very responsive & easy to work with. I will definitely be purchasing more as gifts.
