Revision History
November 4, 2026 (second pass)
Fact-check of the guide's standing assumptions. The Duo row takes its first lab test (iFanr): ~45W at a fixed 15V, about 24 minutes to 50% (was Apple's 60W / 20 minutes), and a plain 45W charger matched AVS. Charge Limit is gated by iPhone model (15 and later), not iOS version, and the 5% steps are iPhone-only. The cycle-count receipt notes that Apple names only the iPhone 15 for 1,000. Rechecked and unchanged: Anker A2687 price, splits and no successor; charger-in-the-box status (US and UK); Battery University's heat figures and Apple's 35°C warning; the wireless column. The 18 Pro and iPad mini still have no lab test.
November 4, 2026
Apple's October releases. The iPad mini row is now the A20 Pro model (18.9 Wh): it fast-charges, 50% in about 30 minutes on 35W or more, and still ships with 20W; Apple's numbers carry daggers until a lab tests it. The MacBook Pro 14" row covers the new M6 and the PROLED XDR 14" (72.6 Wh); thresholds, adapters, and times are unchanged, and the note now names the M6 instead of the base M5. The 16" PROLED matches the 16" row. The Watch line adds Apple's Series 12 claim, 15 minutes for up to 12 hours. Checked, no change: iOS 27's "Understand Thermally Limited Charging" help page describes the existing hot/cold limits, not a new feature; Apple's October 28 redesign of the 70W and 140W adapters (new AC Connector 2 plug) keeps the same wattage and prices.

ChargerLAB's 18 Pro Max review (chongdiantou.com, September 21) replaces that row's Apple claims with measurements: ~53W peak, 41 minutes to 50% at 20W, 15 on an AVS adapter. Corrected the AVS catch: Apple's adapter is not the only one that qualifies, and a non-AVS 140W reaches 50% in 17 minutes, not 20. Added a Fast Charging section on what the term means and which hardware uses AVS. Only the 18 Pro and Pro Max ask for AVS; the Duo and every 17 don't. The MagSafe adapter for the 17 line is 30W, not 35W. Fact-check fixes: Charge Limit on the Mac arrived with macOS Tahoe 26.4, not Sequoia; cold slows or stops charging but does not permanently damage the battery, per Apple; the 14" MacBook Pro's 70W and 96W tiers are the 15- and 18-core M5 Pro; the Apple Watch line now says the wrong cable means no fast charging (the "twice as slow" figure had no source); the iPad Air rows now carry Maplee Tech's measured ~24W (the ~31W credited to Digital Trends couldn't be found); the Anker's single-port figure adds its 150W peak; the 5W adapter model numbers now cite the Apple pages that name them; the Anker port splits now cite Anker's own manual; the iPad Pro 11" takes Apple's ~30 minutes (was a scaled ~25) and the iPad Air rows drop their unsourced times; the AVS section is now "The Fast Charging Recipe"; the Watch line notes the new A3277 cable; the MagSafe receipts name the A3502/A3503 chargers and record a model-by-model recheck of the wireless column; the Mac receipt quotes Apple's current fast-charge wording; the Heat card's "45°C halves lifespan" figure, which no source supports, is replaced with Battery University's storage table and Apple's 35°C warning.

The 18 Pro and 18 Pro Max watt-hours are now the numbers printed on the cell labels, read in iFixit's teardown: 21.75 Wh (was ~21.4) and 16.76 Wh (was ~16.5). The derivation at 3.85 V ran about 1.6% low; the labels imply about 3.9 V. Downstream: the 18 Pro Max's scaled 20W time returns to ~42 minutes, its Faster column to 64%, and its 5W time to ~2h 20m; the 18 Pro's scaled times round the same as before. Still no ChargerLAB test of either phone; the daggers stay.
September 20, 2026
Correction to the 18 Pro and 18 Pro Max watt-hours. The September 15 refresh derived them from the SIM-tray-model capacities (5,391 and 4,056 mAh) at a volts-per-cell figure obtained by dividing the 17 Pro rows' US-model watt-hours by SIM-tray milliamp-hours, an invented 4.06 V. Rederived from the US-model 3C capacities at 3.85 V nominal: 21.4 Wh (was 21.9) and 16.5 Wh (was 16.3). The 18 Pro Max's scaled 20W time moves from ~42 to ~41 minutes and its 5W time from ~2h 20m to ~2h 15m; the 5W receipt row now names the 18 Pro Max. ChargerLAB has not tested the 18 Pro yet; in each of the last three years its first charging test landed three to four days after on-sale day (17 Pro Max September 22, 2025; 16 Pro Max September 24, 2024; 15 Pro Max September 25, 2023), so the † rows should turn into measurements within days, the Duo's in late October.
September 15, 2026
September event refresh. Added iPhone 18 Pro, 18 Pro Max and iPhone Duo (Apple's 60W / 15-minute claim, flagged † pending lab tests, with the AVS adapter catch). Added the MagSafe / Qi2 column to the iPhone table (wireless folded in, as planned in July). Corrected the iPad Pro rows to the M5 (60W fast charging, shipped October 2025; the guide had carried the M4's ~35W since publication). Wearables: Series 12 / Ultra 4 (30 / 45 min to 80%), AirPods 5. Re-verified the Anker Prime 160W (no recall, price down). Swept iOS 27 / macOS 27: no charging changes. Repointed the 17 Pro Max, 17 Pro, 16 Pro Max, 16 Plus and 15 Pro Max links to Apple's tech-specs pages after the product pages went dark. No new MagSafe charger shipped.
July 26, 2026
News sweep since May. Corrected wearables lineup: Apple Watch Ultra 3 (shipped September 2025), not Ultra 2. Added EU/UK no-charger-in-box note to MacBooks. Re-verified iPhone 17 fast-charge specs and the Anker Prime 160W recommendation (no recalls; Anker's 2025-26 recalls covered power banks only). WWDC 2026 announced no new charging features.
May 3, 2026
Noted the USB-PD 240W spec ceiling (Framework now ships a 240W adapter; no Apple device asks for more than 140W). Entry added retroactively July 26.
March 27, 2026
Added sources page. Fixed Apple Watch fast-charging claim in wearables section.
March 26, 2026
Major update for March 2026 hardware refresh: iPhone 17e, MacBook Air M5, MacBook Neo, MacBook Pro M5. Added macOS Tahoe 26.4 Slow Charger warning and granular Charge Limit. Updated all charging tables.
