The Anker Prime 100W earned the top spot because it nails the one thing most charger shoppers actually care about: reliable, efficient power from a brick you can trust. Android Authority measured its efficiency at 92.8%, which means less energy wasted as heat and more reaching your devices. That number matters when you're charging a MacBook Pro at a coffee shop off a shared outlet.


Anker's 3-port design (2 USB-C, 1 USB-A) covers the real-world scenario of laptop + phone + earbuds without needing a power strip. The foldable plug and 170g weight make it genuinely pocketable. Cheap&Cheerful and AllThingsOnePlace both tested heavier, higher-wattage alternatives that outperformed the Prime on raw output, but none matched its balance of efficiency, size, and brand backing.
The brand factor is hard to ignore in a category where a bad charger can damage your $2,000 laptop. Anker's ActiveShield 2.0 monitors temperature 3 million times per day and adjusts output accordingly. Their warranty infrastructure is the best in the business. When AllThingsOnePlace stress-tested cheaper alternatives and watched them thermal-throttle or shut down, the Anker kept delivering clean, stable power at the wattages most people actually use day to day.
One caveat worth mentioning: Android Authority discovered that Anker quietly released a 2024 revision that is 2% less efficient than the 2023 model. Both are sold under the same listing. It's a small difference, but the kind of corner-cutting that deserves scrutiny from a company charging premium prices.
What It Won't Do
The Anker Prime's multi-port power splitting is rigid and inflexible. Plug in two devices and it locks to a 65W/35W split with no dynamic rebalancing. If you're charging two laptops that each want 50W, tough luck. Android Authority also flagged that its PPS mode tops out at 11V, which means Google Pixel 9 Pro XL owners can't hit their phone's maximum 37W charging speed. For a charger at this price point, both limitations feel like missed opportunities.
The Voltme Revo 100W does something that shouldn't be possible at $28: it delivers genuine 100W GaN charging with broad protocol support. Cheap&Cheerful called it a "serious bargain" after running it through the same gauntlet of tests used on chargers costing three times as much.


What makes the Voltme stand out isn't just the wattage-per-dollar math. Cheap&Cheerful verified that it supports Apple, Samsung, Qualcomm Quick Charge, and even Huawei fast charging protocols. That last one is often missing from Western-focused chargers. Whether you're charging an iPhone 16, a Galaxy S25, or a Huawei Mate, the Voltme recognizes and triggers the optimal fast-charge mode.
The thermal management is responsible, if not heroic. Rather than running hot until something fails, the Voltme's protection circuit cuts power at 80-85C. Cheap&Cheerful measured actual delivery at 91-94W during heavy draws. Is that the full 100W? No. Is it close enough at $28? Absolutely.
The three-port layout (2 USB-C, 1 USB-A) gives it the same versatility as the Anker Prime. The foldable plug and 187g weight keep it travel-ready. You're giving up long-duration sustained output, internal build quality, and brand trust. You're getting 95% of the charging performance for 40% of the price.
What It Won't Do
The Voltme cannot sustain 100W for more than about 30 minutes before its thermal protection shuts it down. The 186g weight tells the story: there's a smaller heatsink inside, and physics wins every time. If you're running a power-hungry laptop that draws 80-100W continuously, the Voltme will cycle on and off. For phone charging and laptop top-ups, it's fine. For all-day laptop power, spend more.
