That price is time-sensitive; check the listing for the current price and eligibility. Anker’s US product page listed the charger at $69.99 when checked on October 7, 2026.
What the $45.99 offer includes
The deal is for Anker’s B121B wall charger, which has two USB-C ports, one USB-A port, a built-in smart display, and a USB-C cable. Android Authority reported the $45.99 Amazon price and Prime requirement on October 6, 2026. Anker’s US product page listed the charger at $69.99 when checked October 7, 2026. Those are source-specific, dated prices, not a guarantee of what Amazon charges now.
Android Authority described $45.99 as its best deal seen that year and characterized it as $24 off, or 35% below the recommended retail price. Those are the publication’s deal assessments, not independently verified price-history results. The same report gave the Amazon listing a 4.7-star rating. Separately, Anker’s product page showed 4.9 stars from 173 reviews when checked October 7, 2026; the ratings come from different sources and review pools.

The 100W figure is the maximum output of either USB-C port when that port is used alone. It does not mean every connected device receives 100W. When more than one port is occupied, the charger divides its output according to Anker’s stated allocations:
#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’s stated power allocation |
|---|---|
| One USB-C port | Up to 100W |
| 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 |
The listed combinations show why the charger can suit a laptop-and-accessories setup but may not suit someone expecting three devices to receive high-power charging at once. The actual rate also depends on the connected device and charging conditions; Anker’s compatibility list is not a promise that every listed device charges at its maximum rate.
What the display and other features do
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 findings.
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 models, Samsung S23 and S24, Google Pixel 7 and 8, MacBook Air and Pro, HP Chromebook 14, Steam Deck, DJI Mavic 3, AirPods, and Apple Watch. Compatibility does not establish a particular charging speed for each device.
Size and practical fit
Anker lists the charger at 2.72 × 2.17 × 1.34 inches and 7.47 ounces. Its combination of two USB-C ports, one USB-A port, and a display makes it a reasonable candidate for someone who wants one wall charger for a laptop and smaller devices, while keeping an eye on charging information. Its three-port allocation is the key trade-off if several devices need substantial power simultaneously.
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
- Confirm the live Amazon price and whether Prime is still required; the $45.99 figure was reported October 6, 2026.
- Check the power allocation against the devices you plan to connect, especially if you expect to charge three at once.
- Confirm that your particular device and charging needs are supported; compatibility examples do not guarantee maximum charging speed.
