[4-Pack] 5V 2.1A Power Adapter Cube Dual Port USB Wall Charger - Black | Shared Output Standard Power Brick for iPhone Samsung Galaxy Kindle Wireless Earbuds Smartwatch &amp Android Devices

- Smart Dual-Port & Real 2.1A Output: Equipped with dual USB-A ports, this 5V/2.1A wall charger block provides a total output of 2.1A shared between both ports. It intelligently recognizes your devices' power needs. Note: For optimal performance, it works flawlessly for pairing a high-draw device with a low-draw one (e.g., Phone + Earbuds).

It is designed for everyday multi-device harmony: Pairs a phone (~1.5A) and earbuds/smartwatch (~0.5A) perfectly. When paired with a USB desk lamp, a minor dimming might occur if a power-hungry phone is plugged in together. For maximum speed, sequential charging (one by one) or single-port use is recommended - Universal Compatibility for Tech Essentials: Seamlessly works with old iPhone 8/7/XS/XR, iPad, Samsung Galaxy, Google Pixel, Android phones, Kindles, E-book readers, and small electronics. It is the ultimate everyday power solution for both your legacy gadgets and newest devices - Travel-Ready & Anti-Slip Cube Design: The compact, lightweight cube design fits effortlessly into your pocket, handbag, or carry-on. Featuring a unique refined texture with a secure grip on both sides, it’s incredibly easy to plug and unplug even in tight spaces. With 100-240V universal voltage, this 4-pack ensures you stay connected at home, the office, or abroad - Certified Safety & Cost-Effective 4-Pack: Engineered with an internal multi-protection safety system to guard against over-current, over-heating, and short-circuits.
