The price is time-sensitive: Anker’s US product page listed it at $69.99 when checked October 7, 2026, so confirm Amazon’s current price and eligibility before buying.
What the $45.99 offer covers
The deal report identified the charger as Anker’s B121B, a three-port wall charger with two USB-C ports, one USB-A port, a smart display, and an included USB-C cable. Android Authority reported the Amazon price as $45.99 on October 6, 2026, and said Prime was required. Anker’s US product page listed the charger at $69.99 when checked October 7, 2026. The two figures come from different sources and dates; neither establishes the live Amazon price now.

Android Authority described $45.99 as $24 off and 35% below the recommended retail price, and called it the best deal it had seen that year. Those are the publication’s dated assessments, not independently verified price-history data. The same report listed an Amazon rating of 4.7 stars. Separately, Anker’s page showed 4.9 stars from 173 reviews when checked October 7, 2026; the ratings reflect different sources and review pools.
How the power is divided across its ports
The headline 100W figure is the maximum output from one USB-C port when used alone—not 100W for every connected device. Anker’s listed allocations vary according to which ports are occupied:
#1 Best Overall
- Full-Speed 100W Max Power: Advanced GaN technology delivers a steady 100W output on any USB-C port and sustains peak performance up to twice as long compared to the average 100W charger.
- See Charging in Motion: The high-definition smart display shows real-time details on charging status, temperature, and port performance, giving you instant visibility and control.
- Travel-Sized for Daily Carry: With a foldable plug and a 330% smaller frame, it measures just 2.72 x 2.17 x 1.34", making it easy to slip into a backpack, shoulder bag, or even a coat pocket.
- Adapts to Low-Power Devices: USB-C2 or USB-A automatically switches to 95W + 5W Low-Current Mode when output remains at or below 5W for 1 minute, safely charging earbuds and other low-power devices.
- What You Get: Anker Charger (100W, 3 Ports, Smart Display, Non-Battery), 4.9 ft USB-C to USB-C cable, welcome guide, 18-month warranty, and our friendly customer service.
| Ports in use | Anker-listed power allocation |
|---|---|
| One USB-C port | Up to 100W from that port |
| Two USB-C ports | 70W + 30W, or 95W + 5W |
| One USB-C port and USB-A | 67W + 33W, or 95W + 5W |
| Both USB-C ports and USB-A | 80W + 12W + 7.5W |
These are manufacturer-specified power allocations. In particular, when all three ports are occupied, the listed 80W + 12W + 7.5W split is far short of 100W to each device. The actual charging rate also depends on the connected devices and charging conditions.
Display, safety features, and compatibility
Anker says the display shows live power, voltage, and temperature, along with animated visuals and usage-hour tracking. The manufacturer also lists a foldable plug and ActiveShield 4.0 temperature monitoring. These are advertised features, not independent test results.
Rank #2
- 200+ Countries, One Charger: Built-in US, UK, and EU plugs support Type A (US / Canada / Japan / China), Type C (EU), and Type G (UK / Singapore) outlets. AU plug not included.
- Weight and Volume: Weighs 9.3 oz—about the weight of a full 250 ml drink can. It measures 3.74 × 1.98 × 1.59 in—about the footprint of a credit card and the thickness of a ping-pong ball. Fits a bag pocket. Not a battery.
- Charge 4 Devices, Up to 100W for Laptops: Charge up to four devices through 3 USB-C ports and 1 USB-A port. With PowerIQ 4.0 intelligently distributing power across connected devices, USB-C1 or USB-C2 deliver up to 100W when used individually for fast laptop charging.
- Local Voltage Detected in 1 Second: A wide 100–275V input range supports charging across different voltage regions. The charger detects local voltage in just 1 second, and the 1.3-inch LCD screen lets you monitor the voltage zone, power output, and temperature in real time.
- Secure Plug Design + NRTL Certification: The compact flat-plug design sits close to the wall and helps the charger stay securely connected, even in loose outlets. Certified by NRTL, it also features 320V overvoltage protection and more than 10 million temperature checks per day.
Anker lists compatibility examples that include iPhone 12–16 and SE series, Samsung S23/S24, Google Pixel 7/8, MacBook Air and Pro, HP Chromebook 14, Steam Deck, DJI Mavic 3, AirPods, and Apple Watch. Compatibility does not mean every device will charge at its maximum rate; the device and charging conditions affect the result.

Size and who this charger suits
Anker lists the B121B at 2.72 × 2.17 × 1.34 inches and 7.47 ounces. With two USB-C ports and one USB-A port, it may suit someone seeking a single wall charger for a laptop and smaller devices, particularly if seeing charging information on a display is useful. It is not a three-device, 100W-per-port charger: the manufacturer’s all-ports allocation is 80W + 12W + 7.5W.
Rank #3
- 100W Multi-Device Fast Charger: Power up three devices simultaneously with a total of 100W output through two USB-C and one USB-A port for efficient power distribution.
- Maximum Power with USB-C: Each USB-C port delivers a full 100W, efficiently charging your 14-inch MacBook Pro (M3 Pro) from 0 to 50% in just 30 minutes.
- Super Compact: Its foldable prongs and compact design make it perfect for on-the-go use, easily fitting into any bag or pocket without the bulk.
- No More Loose Connections: Built to remain firmly connected with thicker prongs for improved grip, a well-balanced design for steady support, and drop-proof structure.
- What You Get: Anker Prime Charger (100W, 3 Ports, GaN), welcome guide, 24-month warranty, and our friendly customer service.
What to check before buying
- Check the Amazon listing for the current price and whether Prime is still required; the $45.99 figure was reported October 6, 2026.
- Confirm the B121B model and the listed port-power allocation against your devices’ needs.
- Distinguish the Amazon rating reported by Android Authority from the rating shown on Anker’s own product page; they are not the same review pool.
