Carrying three separate proprietary power bricks—one for your 16-inch laptop, one for your tablet, and one for your smartphone—is a relic of the past. The widespread adoption of Gallium Nitride (GaN) semiconductor technology and the USB Power Delivery 3.1 Extended Power Range (EPR) standard has made single palm-sized chargers capable of delivering up to 240W across multiple ports simultaneously.
However, not all multi-port chargers are engineered equally. Cheap multi-port chargers suffer from three critical flaws:
1. Aggressive power renegotiation: Plugging a phone into Port 2 cuts power to Port 1 for two seconds, repeatedly disconnecting your laptop.
2. High ripple voltage: Poor filtering capacitors spew electrical noise that degrades lithium-ion battery health over time.
3. Severe thermal saturation: Surface temperatures exceeding 75°C, triggering aggressive emergency thermal throttling.
We spent two weeks testing the two undisputed titans of consumer power electronics: the Anker Prime 160W (GaNPrime) and the Ugreen Nexode Pro 160W using an electronic load tester, a Rigol digital oscilloscope, and a FLIR thermal camera.
Here is the objective engineering data.
Electrical Specifications and Oscilloscope Ripple Testing
FLIR thermal imaging after two continuous hours of 140W load reveals heat dissipation efficiency across thermal potting compounds.
Clean, stable voltage is paramount for delicate modern electronics. High ripple voltage (Vpp) introduces high-frequency noise that strains motherboard voltage regulator modules (VRMs).
| Test Parameter / Metric | Anker Prime 160W (3C1A) | Ugreen Nexode Pro 160W (3C1A) | Engineering Verdict |
|---|
| Max Single-Port Delivery | 140W (28V / 5A EPR) | 140W (28V / 5A EPR) | Both fully power a 16-inch MacBook Pro at maximum speed |
| Ripple Voltage @ 100W Load | 18.4 mV Vpp | 32.1 mV Vpp | Anker’s planar transformers deliver cleaner, studio-grade DC current |
| Full Load Efficiency (160W) | 92.4% | 89.8% | Anker converts less AC wall energy into wasted heat |
| Surface Temp (2-Hour 140W Load) | 58.2°C | 68.7°C | Anker’s aerogel thermal potting keeps chassis 10°C cooler |
| Weight | 385 grams | 315 grams | Ugreen is 18% lighter and more compact for travel |
| Port Power Drop on Re-plug | Zero Drop (Continuous Power) | ~1.5s Disconnect Blink | Anker uses dynamic split buck-boost without resetting active ports |
Teardown and Internal Thermal Engineering
Cracking open both plastic chassis reveals radically different component layouts:
Anker Prime 160W:
- Uses
GaNPrime architecture featuring synchronous GaN FETs on both primary and secondary stages.
- The entire internal PCB is submerged in dense, custom thermal potting compound combined with high-grade aluminum shielding.
- Incorporates
ActiveShield 2.0, which monitors internal temperatures over 3 million times per day, gracefully stepping power down by 5W increments rather than cutting off power abruptly.
- Crucially, when you plug a smartphone into USB-C2 while a laptop is charging on USB-C1, Anker's intelligent MCU recalculates power budgets dynamically without dropping the connection on USB-C1.
Ugreen Nexode Pro 160W:
- Uses a stacked
AirPyra design that reduces physical volume, making it one of the slimmest 160W bricks on the market.
- High-efficiency solid-state capacitors handle voltage smoothing effectively.
- However, when a secondary device is plugged in, the internal handshake controller briefly resets all ports to renegotiate the USB-PD PDO (Power Delivery Object) table, causing connected monitors or laptops to blink off momentarily.
Travel Usability: Wall Plug Stability
Low Vpp ripple voltage under twenty millivolts prevents premature wear on laptop battery charging circuits.
Both chargers feature folding prongs. Because high-wattage GaN chargers concentrate heavy transformers into a small footprint, they can droop and fall out of loose airplane or hotel wall sockets.
- Anker includes a detachable silicone stabilizing suction ring in the box that prevents the charger from slipping out of vertical outlets.
- Ugreen positions its center of gravity closer to the wall prongs, resulting in slightly less leverage pull.

The Verdict
- Winner for Professional Workstations & Audio Engineers: Anker Prime 160W. Its ultra-low ripple voltage (under 20mV), continuous power delivery without connection blinks, and superior thermal dissipation justify its higher price tag.
- Winner for Frequent Travelers & Commuters: Ugreen Nexode Pro 160W. It delivers identical 140W single-port charging performance in a substantially lighter, more compact chassis at a more competitive price point.
