Vivo USB Charger 44W FlashCharge Model 5434820 — Fast USB Power Adapter

The Vivo USB Charger 44W FlashCharge Model 5434820 is a compact fast USB power adapter designed to deliver up to 44 watts of charging power for compatible smartphones, tablets and small accessories. Featuring FlashCharge charging technology, the adapter is intended for everyday home use and travel, offering faster recharge times compared with standard chargers while maintaining a small, portable form factor.

Advantages

This charger provides a high power output in a compact enclosure, enabling faster charging sessions for supported devices. FlashCharge technology optimizes charging speed and manages power delivery to reduce overall recharge time. The adapter's lightweight design and foldable plug (if applicable) make it convenient to carry in a bag or pocket for on-the-go charging. Built-in safety circuitry helps protect against overcurrent and short circuits during normal use.

Suitable for

• Fast charging compatible smartphones and Android devices
• Tablets that accept higher-watt USB charging
• Small USB-powered accessories such as wireless earbuds and power banks
• Home, office and travel use where compact charging is required

When it may not be suitable

The adapter may not provide maximum charging speed for devices that require proprietary high-wattage protocols beyond standard USB power delivery or the specific FlashCharge profile. Devices that rely on manufacturer-specific chargers for optimal battery care may not charge at their fastest rate with this adapter. For high-capacity laptops or devices requiring USB-C PD at greater than 44W, this charger will be underpowered.

Key specifications

• Maximum output power: 44 W
• Connector type: USB output (refer to product images or packaging for exact port type)
• Charging technology: FlashCharge fast-charging support
• Form factor: Compact portable wall adapter
• Intended use: Smartphones, tablets, and small USB-powered accessories

How to use

Connect the charger to a suitable AC mains socket and attach a compatible USB cable between the adapter and your device. The adapter will negotiate the appropriate power level with the connected device; allow the device to complete its charging cycle according to the manufacturer's battery guidance. Unplug the charger from the mains when not in use and store it in a dry place. Always use cables and devices that are in good condition and rated for the intended charging power.

What to consider before purchase

• Verify that your device supports USB fast charging or the FlashCharge profile to benefit from higher speeds
• Check the port type and cable compatibility for your device (USB-A, USB-C or other)
• Confirm that 44 W maximum output meets the power requirements of your device
• Ensure the adapter's physical plug type is compatible with your local power outlets or consider a travel adapter

Usage recommendations

Use the Vivo 44W FlashCharge adapter with cables rated for the charge current and avoid simultaneous charging of multiple high-draw devices from a single output. For best results, pair the charger with devices that explicitly list support for FlashCharge or compatible fast-charge protocols. Store and transport the adapter in a protective pocket to prevent damage to the plug or ports.
