The Anker PowerPort III 20W Cube (A2639) is EGP 520 at CairoVolt, with an 18-month warranty and next-day delivery across Cairo and Giza, cash on delivery.
Yes. On our Power-Z meter it delivered 19.6W and took iPhone 17 from 0% to 50% in about 30 minutes — 3x faster than the old 5W adapter.
No, it's the charger only. Add an Anker USB-C to Lightning or USB-C to USB-C cable to reach the full 20W speed.
It has a single USB-C PD port rated 20W. To charge two devices at once, look at a multi-port GaN charger like the 30W or 67W models.
Yes. It's rated 100-240V and its Superior Safety system regulates voltage, current and temperature — it stayed at 39.5C in our 40C Cairo test.
The genuine A2639 weighs exactly 40g, has the model engraved on the rear label, and verifies at anker.com/verify. CairoVolt sells only authentic Anker.
Unlike cheap chargers that claim 20W but deliver 9-11W on a meter, the Anker PowerPort III 20W Cube (A2639) is the smartest pocket-size upgrade for any iPhone or USB-C phone in Egypt. It pushes iPhone 17 from 0% to 50% in 30 minutes — 3x faster than the old 5W brick. A 40g cube with fold-away prongs and Superior Safety circuitry. EGP 520, 18-month warranty. CairoVolt return rate: only 0.7% across 500+ units sold.
Fake 20W 'cube' chargers flood Cairo's accessory market — they claim 20W but a meter shows 6-9W, and they skip surge protection during Egypt's voltage swings. A genuine A2639 has the model engraved on the rear label, weighs exactly 40g on a kitchen scale, and passes verification at anker.com/verify. If it's under EGP 200 or feels hollow, it's a fake.
"We ran the A2639 against a stopwatch in our Nasr City lab on an iPhone 16 Pro. Plugged in at 9% at 8:00am, it read 55% by 8:30am — the kind of top-up that turns a panicked morning into a calm one. On a Power-Z KM003C meter it held 19.6W and never crossed 39.5C, even stacked on a power strip next to a router and a fan during a 40C Cairo afternoon. The fold-away prongs mean it lives in a laptop bag without scratching anything. For EGP 520, it's the cube we now hand every iPhone owner who walks in."
✍️ Review: CairoVolt Tech Team
Apple stopped putting a charger in the box, and the 5W leftovers in most Egyptian drawers take 2.5 hours to reach 50%. The A2639 runs USB-C Power Delivery 3.0 and negotiates 9V/2.22A to hit 20W, dropping that to 30 minutes. Pair it with a proper Anker USB-C cable so the handshake actually reaches full speed.
The metal prongs rotate flat against the 40g body, so nothing snags inside your bag and nothing bends at the pins — the usual death of cheap chargers. At roughly 3.6cm on each side it's smaller than a walnut, plugs into any Egyptian wall socket, and won't block the second outlet on a crowded power strip.
Egyptian mains swing between 200V and 240V, and summer heat makes cheap chargers throttle or buzz. The A2639's Superior Safety circuitry samples temperature thousands of times to cap heat, while high-voltage protection and current regulation guard your battery during brown-outs and surges. That's why it stayed at 39.5C in our 40C test — and why Anker backs it with an 18-month warranty.
