GM extension board with usb
⭐⭐⭐⭐⭐ Excellent extension board with a premium design and solid build quality. The USB-A and Type-C ports are very convenient for charging phones without extra adapters. The sockets hold plugs firmly, and the 1.8 m cable is perfect for everyday use. Great value for money and highly recommended for home or office use.

Clean, Classy Design – Highly Recommended
Excellent extension board with a clean, premium-looking design. The white finish gives it a modern and classy appearance, making it look much better than typical extension cords. It feels well-made and works perfectly. If you need an extension board, this is definitely worth buying.

Review after 6 months usage
Bought it in December 2025. There is enough space between the ports. The cord length is sufficient. I use the USB port to charge my smartwatch. The charging speed is not great. However, charging my phone using a separate charger and adapter works well.

DON'T BUY THIS. I MEAN IT.
This extension board has the confidence of a premium product and the performance of a group project member who only shows up on presentation day. - The 3 power sockets work, but the grip is so loose that a 2-pin plug can disconnect if you look at it aggressively. - The USB-C and USB-A ports are basically decorative lighting. They charge slower than my motivation on a Monday morning. - Claims to be a 2000W extension board, but feels like it starts questioning its life choices the moment you plug in anything heavier than a phone charger. - Build quality gives strong "assembled during lunch break" vibes. And then comes Amazon's return policy. Apparently, if you don't like the product, your reward is... another copy of the same product. It's like ordering bad food and being offered a free refill of the same dish. If you're on a budget, save your money. If you can spend a little more, buy an Anchor by Panasonic extension board and enjoy the revolutionary concept of plugs staying plugged in. Verdict: This extension board isn't an extension board. It's a practical demonstration of why product reviews exist.

Perfect for multi purpose.
Loved the design and the quality of this extension. I have been search for an extension which could complete my needs but i couldn't find one until now! Maybe. It got usb port which is helpful for me as I use mobile cooler so I don't need any adapter anymore. The cord size could do better as the name extension doesn't fit it really well. Other then then that I'm having no issues with the product.
