What the Gemini UW505 looks like

The Gemini UW505 is a compact wall charger with a rectangular body roughly the size of a standard USB power adapter. The main unit is black plastic with a matte finish, measuring about 2.4 inches wide, 1.5 inches tall, and 1 inch deep. Two vertical USB-A ports sit on the front face, stacked one above the other, with small LED indicator lights between them.

The charger has a flat rectangular prong design that folds into the back of the unit. When the prongs are extended, the overall depth increases to about 1.5 inches. The cable connection point is on the bottom edge, where a short USB cable (usually around 3 feet) is permanently attached with a USB-A connector on the free end.

The model number "UW505" is printed on the bottom or back of the unit in small white text. You may also see "Gemini" branding on the front or top surface. The device is lightweight, typically under 4 ounces, making it easy to carry in a bag or pocket.

Key Takeaways

  • The UW505 is a black rectangular wall charger about the size of a standard phone charger, with two USB-A ports on the front.
  • The charger has a permanently attached USB cable with a USB-A connector, not a detachable cable.
  • Two LED indicator lights sit between the USB ports and glow when the charger is powered and actively charging.
  • The model number "UW505" is printed on the bottom or back of the unit in small text.
  • The prongs fold flat against the back for storage and travel.

The USB ports and cable

Both USB-A ports on the front are standard full-size USB connectors, not the smaller USB-C or micro-USB types. They are positioned vertically, one directly above the other, with about a quarter-inch of space between them. This spacing allows you to plug in two devices at once, though larger charging cables or adapters may block the lower port if the upper one is occupied.

The attached USB cable is approximately 3 feet long and terminates in a standard USB-A connector. This cable cannot be removed or replaced, so if it becomes damaged, the entire charger must be replaced. The cable is typically black to match the main unit.

The LED indicator lights

Two small LED lights sit on the front face between the two USB ports. These lights are usually blue or white and serve as power indicators. When you plug the charger into a wall outlet, both lights illuminate to show the unit is receiving power. The brightness of these lights can vary depending on the ambient light in the room.

The lights remain on whenever the charger is plugged in, regardless of whether devices are actually charging. This is normal behavior and does not indicate a problem. If the lights do not turn on when the charger is plugged in, the outlet itself may not be working, or there may be an issue with the charger.

The power prongs

The UW505 has two flat rectangular prongs on the back that fold flush against the unit for storage. These are standard US-style prongs, so the charger works with any standard American wall outlet. The prongs are spring-loaded and fold out to a 90-degree angle when you need to plug the charger in.

When the prongs are folded in, the charger is flat and compact enough to fit in a pocket or small bag. The prongs do not lock in place when extended, so they can fold back in if pressure is applied. This design is intentional and allows the charger to be more portable than models with fixed prongs.

Size and weight comparison

The UW505 is comparable in size to most dual-port USB wall chargers on the market. It is slightly larger than a single-port charger but smaller than some multi-port models with three or more ports. If you have used a standard two-port phone charger before, the UW505 will feel familiar in your hand.

The charger weighs very little—typically between 2 and 4 ounces—making it one of the lighter options for dual-port charging. The plastic body is durable but not rugged, so it should be handled with normal care to avoid cracks or damage to the attached cable.

Color and branding details

The entire unit is black, with no color variations or accent stripes. The Gemini branding is usually printed in white or silver text on the front or top surface. The model number "UW505" appears in smaller text, typically on the bottom or back of the unit where it is less visible during normal use.

Some versions may have slightly different text placement or branding depending on the production batch, but the overall black color and rectangular shape remain consistent. If you are trying to confirm you have the correct model, the "UW505" text is the most reliable identifier.

What to check if you are unsure

If you have a charger that looks similar but you are not certain it is a UW505, check the bottom or back of the unit for the model number. The text is small but should be visible under normal lighting. You can also count the USB ports—the UW505 has exactly two ports, not one or three.

Another way to confirm is to look at the cable attachment point. The UW505 has a permanently attached cable that exits from the bottom edge of the unit. If the charger has a removable cable or a different connection style, it is a different model.

Frequently Asked Questions

Can I replace the cable if it gets damaged?

No, the cable on the UW505 is permanently attached and cannot be removed. If the cable becomes frayed, cracked, or stops working, you will need to replace the entire charger. This is a trade-off for the compact design—the attached cable saves space but reduces repairability.

Are the USB ports full-size or mini?

Both ports are standard full-size USB-A connectors. They are not USB-C, micro-USB, or any other smaller format. This means you can plug in most older phones, tablets, and USB devices without needing an adapter.

Do the prongs stay folded when I carry it?

The prongs are spring-loaded and will stay folded as long as you do not apply pressure to them. They are not locked in place, so rough handling or pressure in a bag could cause them to unfold slightly. For travel, you may want to use a small pouch to keep the prongs secure.

What color is the charger?

The UW505 is entirely black with a matte plastic finish. There are no color options or variations—all units are the same black color with white or silver text for branding and the model number.

How bright are the LED lights?

The LED lights are moderately bright and visible in most lighting conditions. In a dark room, they are quite noticeable. In bright daylight or under strong overhead lights, they may be harder to see. The brightness does not change based on charging activity—the lights stay the same brightness whenever the charger is plugged in.
