Power plays & comment brawls
Werewolf Vflex Adapter Review
The clutter-killing power gadget reviving old tech—and dividing the internet
TLDR: VFLEX is a programmable power adapter that revives old gear and cleans up messy setups. Commenters are split between praise for nostalgia-saving convenience and warnings about reverse polarity and charger quirks, with audiophile debates and “Jeff made me buy it” confessions fueling the fun.
The Werewolf VFLEX Adapter crash-landed into comment sections like a power tool from the future, and the crowd went wild. Fans bragged about reviving ancient gadgets—like one user who brought a 2000s Nikon Coolwalker back to life—posting “time capsule unlocked” memes. Skeptics zeroed in on those orange, reverse-polarity plugs, warning newbies that flipping plus/minus can turn sentimental tech into toast. Then came the hype train: thanks to Jeff Geerling, half the thread confessed impulse buys (“Got me again, Jeff”), while others joked about paying the “Jeff-tax.” It’s tidy power meets comment chaos.
For the non-nerds: VFLEX lets you set power levels through the vflex.app site or an iPhone app. USB-C PD (Power Delivery) is how your charger “speaks” voltage, and not all bricks speak the same dialect. Cue “charger roulette” memes: the 60W Jackery gives standard steps (5, 9, 12, 15, 20V), while Werewolf’s 20W Mag Pack taps out near 11V. Audiophiles stormed in, swearing their Schitt gear “sounds cleaner,” while the measurement crowd yelled “placebo,” launching an “AudioPhool vs Measurement Mafia” smackdown. Privacy nerds debated whitelisting the site in firewalls; pragmatists shrugged, “it’s just a control page.” Verdict: a clutter-killer with enough hot takes to power a town
Key Points
- •The Werewolf VFLEX Adapter system provides programmable power via USB‑C PD as a less cluttered alternative to bench power supplies.
- •A real-world use case revived a Nikon Coolwalker (≈6V requirement), enabling recovery of stored photos.
- •Some VFLEX adapters with orange connectors use reverse polarity (center‑negative, outer‑positive), important for devices like the Brother PT‑210.
- •Voltages are set through vflex.app using a Chrome browser or an iPhone app; firewall whitelisting may be needed.
- •PD voltage availability depends on the source: a 60W Jackery offered standard PD steps, while Werewolf’s 20W Mag Pack negotiated more flexible voltages up to ~11V.
