The Gemini UW505 is a compact wall charger with a rectangular body and two USB ports

The Gemini UW505 is a dual-port USB wall charger made by Gemini, a manufacturer of mobile device accessories. It has a flat, rectangular shape roughly the size of a deck of cards — about 2.5 inches wide, 1.5 inches tall, and less than an inch deep. The body is typically white or black plastic with a matte finish.

The two USB-A ports sit side by side on the front face, spaced far enough apart that you can plug in two standard USB cables at the same time without them touching. The prongs fold flat against the back when not in use, which is why you will sometimes see it called a foldable charger. When you need to plug it in, the prongs swing out 90 degrees to sit perpendicular to the wall.

The model number UW505 is printed on the bottom or back of the unit, usually in small text. This is how you confirm you have the right charger if you are looking at one in a drawer or trying to match it to a manual.

Key Takeaways

  • The UW505 is a white or black rectangular charger about the size of a playing card, with two USB-A ports on the front face.
  • The power prongs fold flat against the back and swing out when you need to plug it into a wall outlet.
  • The model number UW505 is printed on the bottom or back in small text, which confirms you have the right unit.
  • Both USB ports can deliver power at the same time, so you can charge two devices from a single wall outlet.

Where the ports are located

Both USB-A ports are on the front face of the charger, arranged horizontally next to each other. They are standard rectangular USB-A openings — the kind you find on older phones, tablets, and many other devices. The ports are recessed slightly into the plastic body, which means the connector on your cable sits flush and does not stick out awkwardly.

The spacing between the two ports is wide enough that most USB cables can plug in side by side without the connectors or cable heads colliding. If you are using thick cables or cables with large connector heads, you may find one port is easier to access than the other, but both will work at the same time.

The folding prongs and how they work

The two metal prongs on the back of the charger fold flat when not in use. This makes the charger thinner and easier to pack in a bag or drawer. When you are ready to use it, you pull the prongs outward until they are perpendicular to the body — they will click or snap into place at a 90-degree angle.

The prongs are standard two-pin American outlets, so they work with any wall socket in the United States. If you are traveling outside the US, you will need a plug adapter to use this charger. The prongs themselves are not adjustable — they only fold and unfold, they do not rotate or move side to side.

Size and weight compared to other chargers

The UW505 is smaller and flatter than most older wall chargers but larger than modern single-port fast chargers. It weighs a few ounces and fits easily in a pocket or small bag. The rectangular shape means it does not take up much space on a shelf or nightstand, and the folding prongs prevent the metal from scratching other items when packed.

Because it has two ports, it is bulkier than a single-port charger but more compact than carrying two separate chargers. If you regularly charge two devices at once, the UW505 takes up less space than the alternative.

What is printed on the body

The Gemini brand name and logo appear on the front or top of the charger. The model number UW505 is printed on the bottom or back, usually in small black or white text depending on the color of the unit. You may also see electrical specifications printed somewhere on the body — typically the voltage (usually 100-240V) and the total amperage the charger can deliver.

Some units have a small LED indicator light, usually near the top or on the side, that glows when the charger is plugged in and delivering power. This light is optional and not all UW505 units have one, so do not use its presence or absence to determine if you have the right model.

Common places you might find one

The Gemini UW505 was sold as an accessory for older smartphones and tablets, particularly Android devices. You might find one in a junk drawer, in the original box with an old phone, or in a bag of old cables and chargers. Because it is an older model, it is less common in new retail stores but still shows up in used electronics listings and secondhand shops.

If you are trying to identify a charger you already own, check the bottom or back for the UW505 label. If you are looking to buy one, search for the model number online to see current availability and pricing, as stock varies by seller.

Frequently Asked Questions

How fast does the UW505 charge devices?

The UW505 delivers standard 5V power through USB-A ports, which is slower than modern fast chargers. It works fine for phones and tablets but takes longer than newer chargers. The exact charging speed depends on what device you are charging and its battery capacity.

Can I use the UW505 outside the United States?

The prongs are designed for US outlets only. If you travel internationally, you will need a plug adapter that converts your destination's outlet shape to a US two-pin outlet. The charger itself works on any voltage between 100-240V, so the adapter is all you need.

Is it safe to charge two devices at the same time?

Yes, both ports can deliver power simultaneously. The charger is designed to split its total power between the two ports, so charging two devices at once will be slower than charging one device alone, but it is safe and normal.

What devices can I charge with the UW505?

Any device with a USB-A cable can charge from the UW505 — older phones, tablets, portable speakers, cameras, and other accessories. Modern phones with USB-C ports will need a USB-A to USB-C cable adapter or cable to work with this charger.
