Overview
Power your 9V devices easily from a standard 5V USB source with this USB DC 5V to 9V boost converter cable. Featuring an integrated step-up voltage regulator, this cable allows you to convert 5V input (from USB ports or power banks) to a stable 9V DC output, perfect for powering routers, Arduino boards, small electronics, LED strips, portable fans, and more.
Its compact design makes it ideal for use on the go, especially for DIY projects or backup power setups. Simply plug the USB into a 5V power source and connect the DC plug to your 9V device—no software or configuration required.
Features
- Step-Up Converter – Converts 5V USB input to 9V DC output
- Built-in Protection – Over-current, short-circuit, and thermal protection
- Plug & Play – No drivers or configuration needed
- Universal Compatibility – Works with routers, microcontrollers, modems, mini fans, LED devices, etc.
- Portable & Lightweight – Ideal for travel or emergency power solutions
Package Includes:

Great hose!
Style: Standard Grip, Size: 100ft, Color: Chartreuse
5 stars without hesitation. This Flexzilla Garden Hose 5/8 in. x 100 ft. is legitimately one of the best hoses I’ve used. It’s actually flexible like advertised, doesn’t fight you every time you move it around, and it feels way more durable than the cheap stiff hoses from big box stores. I honestly don’t understand a lot of the complaints, mine has held up great, doesn’t kink nearly as bad as others I’ve owned, and is super easy to coil up. Solid hose.

If you want to buy your last hose then flexzilla is your hose.
Style: Standard Grip, Size: 50ft, Color: Chartreuse
O.K. if you are reading my review I can honestly say that I don't think anyone knows what they are buying with this hose like I do as Amazon has the record of when I bought 100 feet of this hose. Long Long Long term user=purchased in 2017. I used this hose today and it looks-feels-works like it did the day I hooked it up on my reel. So flexible you can use it for a tourniquet if required. Hot-cold it don't matter this hose is the best. I am 70 yrs. old and it is the best hose I ever used in my life. Buy this hose once and then be done. Never kinks and not to heavy when moving around. Buy some and get on with whatever work you need to wash and then roll it up and forget about it.

Hose kinks.
Style: Standard Grip, Size: 100ft, Color: Chartreuse
I bought this hose 2 months ago and really like how light it is and easy to pull around the yard. However, I am having a problem with it kinking all of the time. It is really frustrating to have to go back and straighten it out when I am watering.

Excellent product.
Style: Standard Grip, Size: 50ft, Color: Chartreuse
I've dealt with many different brands of hoses, took into account quality and price. After many disappointing purchases I can finally say "I got the right one this time". It is exactly as advertised, lightweight, flexible and very easy to handle. You won't go wrong with Flexzilla garden hose!!!

There is no substitute to Flexzilla Hose
Style: Standard Grip, Size: 100ft, Color: Chartreuse, Style: Standard Grip, Size: 100ft, Color: Chartreuse
I absolutely love this hose! I purchased roughly 300 feet last year for use in my garden. It's extremely light and durable when you are dragging it around. For the most part it is kink free. If there does happen to be a kink down the line, a quick tug fixes the problem. No leaks, no shrinkage. Easy to install on any hydrant. DEFINITELY compact compared to other heavy hoses. The best part, it's super easy to coil it back up and hang in the tool shed. So I ordered a couple more 100 footers. I will definitely buy more.
