The USB TO RS232/485/TTL is very easy to use, fully automatic transceiving without delay. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipments and/or applications with high communication requirement.
Features
1. USB TO RS232, USB TO RS485, USB TO TTL (UART)
2. Adopt original FT232RL, fast communicating, stable and reliable, better compatibility
3. Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
4. Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
5. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
6. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance
7. Fully automatic transceiver circuit with no delay, ensures the USB port communicates with different interfaces fastly and stably, without interfering each other
8. Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch
9. Aluminium alloy enclosure with sand blasting and anodic oxidation, CNC process opening, solid and durable
10. 3 LEDs for indicating the power and transceiver status
11. High quality USB-B and RS232 connectors, smoothly plug/pull

22 outlets. Super easy to use. Extremely happy with purchase.
Size: 6.5 FT, Color: Black
22 outlets!
I had 2 battery backups but, after 5 years, the battery died and could not be easily replaced.
I moved all my plugs to one, easy to use strip.
Lots of room for block plugs. Generous room between outlets.
3 USB C and 3 USB A outlets mean I can plug in chargers for my devices.
Extremely happy with my purchase. Great company. Lots of choices from DEPOW but this one allowed me to plug in all my block plugs without covering other plugs.
Great color. Extremely well made.
Will purchase again.
Generous 6.5 foot cord. My others had short 3 foot cords which barely reached.

Perfect for the bathroom
Color: Dark Brown, Size: 15.7 inch, Color: Dark Brown, Size: 15.7 inch
I recently installed the these floating shelves with Wire Storage Basket, and I'm genuinely impressed with their blend of style and practicality. The shelves were easy to mount, and the included hardware felt sturdy, ensuring they're securely in place. Right off the bat, I noticed the quality of the materials; the wood has a nice finish, and the wire basket is well-constructed, promising durability.
Functionality is where these shelves truly shine. The wire basket is perfect for storing smaller items, keeping them organized and within easy reach, while the shelf space is great for displaying decorative pieces. They've helped me declutter my space and add a touch of rustic charm at the same time.
Aesthetically, these shelves look great in my bathroom. Overall, these floating shelves have exceeded my expectations, offering a stylish and functional storage solution that's built to last.

Looks great and holds firm.
Color: Dark Brown, Size: 15.7 inch
Looks great in my bathroom. Great functionality and good quality shelving and frame. I wouldn't stack an Encyclopedia Britanica on it, but it will solidly hold bathroom items with no problem. I added a couple of motion-activated rechargeable light on each side of this unit and it really looks great while serving a very practical purpose.
