TL,DR: Spend the $10-14 to protect your $600+ phone and invaluable data.

I don’t usually recommend a specific product because everyone’s needs are different but this is something that anyone with a phone/tablet that charges over USB, including most ‘dumb’ phones nowadays, can and should use.

The LockedUSB Adapter – USB Charger Firewall & Power Optimizer is a little (and cheap) device does two very important things:

1. It removes any and all data that may be passing from your device to the charging port. Why does this matter? With the right tools and 5 minutes I can make any of those USB charging ports in hotels, airports, Starbucks, etc. steal all of the data off of your phone or, worse, install a trojan, even if it has a lock screen password. Perhaps you are simply by someone else’s computer and want to charge your phone but don’t want to give that computer access to your device? Just use this as a data shield and you will only get power.

2. It ensures a consistent and safe charge for your device. Many chargers and USB ports do not deliver the recommended power to your device and, even worse, the power level often fluctuates. This leads to slow charge times in the short run and kills your battery life in the long run. Once it even caused my touch screen to short circuit!

Used it in several airports and it passes charge and blocks data. does the job efficiently. I have it attached to the end of my primary charging cable for my phone. Love it.

“I received mine in China yesterday. Thanks guys for the well managed project and keeping us up to date with regular updates each step of the way… but I like the carry case you included, and it seems well made (used good quality plastics). I agree it is larger than I thought it would be, but that isn’t a deal breaker for me … Main thing is that it stops data transmission!!!

I’m really glad I supported this project. Well managed and your first iteration already looks well made and professional (if a little larger than expected). Very happy supporter ~ thank you!”
