Phones rarely fail all at once. They fail in small ways: 4% battery on a long drive, a video call with the screen sliding off a mug, and a tutorial you filmed without once seeing yourself in frame.
Most of those problems are fixed by a cheap accessory, and the fixes now cost less than a takeaway.
Best mobile accessories under $50 on Amazon
Gadinsider has been analysing the small devices which help in making a mobile device easier to use, and the under-$50 end of Amazon turns out to be busier than you might expect.
The chargers have shrunk in size and gained speed, speakers also act as stands, and even recording video of yourself has its own dedicated gadget. Some gadgets perform one particular function, while others try to do multiple jobs at once.
1. SAMSUNG 45W super-fast charging USB-C wall charger with cable
The Samsung 45W charger is a USB-C wall adapter that comes with a 1-metre USB-C cable. Samsung says it can take a Galaxy Ultra phone from 0 to 60% in 30 minutes. The listing also names recent iPhones and other USB-C devices.
Key features and specs
- Power: 45W, using Power Delivery (PD)
- Charging speed: 0 to 60% in 30 minutes on Galaxy S23 to S26 Ultra models (per Samsung)
- Cable: 1m USB-C to USB-C, with a reversible connector
- Input voltage: 100 to 240 V
- Safety: Protection against short circuits, overheating, over-voltage, over-current and overcharging (per Samsung)
- Compatibility: Samsung Galaxy S, Note and Ultra models, iPhone 15 to 17 models and other USB-C devices (per the listing)
- Included: Charger, USB-C cable, leaflet
Performance
However, according to Samsung, other PD devices have charging speeds that differ; thus, the 45W charger applies only to phones that are compatible. The 100 to 240V charging speed is ideal for travel purposes; however, you need to ensure that the plug is appropriate for where you will be going.
Pros
- 45W charging with a cable in the box
- Wide voltage range for travel
- Samsung lists compatibility with Galaxy and iPhone models.
Cons
- Charging rates vary for devices outside Samsung's list.

2. Acer Prime 3-in-1 magnetic charging station for Apple
The Acer Prime is an upright wireless charger that handles an iPhone, an Apple Watch and AirPods at once. Its magnetic phone pad rotates 360 degrees, and the base is weighted with anti-slip pads. The listing says a charger and USB-C cable are included.
