How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a replacement case with a larger built-in battery and a simple one-touch pairing button, choose Yitonglian Charger Case Replacement; if you need dual charging — USB-C and wireless — plus a two-year warranty and automatic reconnection when you open the lid, choose Pyhsz Charging Case Replacement.
• Yitonglian's biggest strength: a 450mAh battery that adds up to three full recharges for your earbuds, backed by a 2.5-hour case recharge time and a roughly 30-minute top-up to 100%.
• Yitonglian's biggest trade-off: it pairs by pressing a button, and the sheet lists no wireless charging and no stated warranty — so it's a straightforward "plug it in" case.
• Pyhsz's biggest strength: it charges two ways (Type-C and wireless), reconnects automatically when you open the lid, and carries a 2 Year Warranty.
• Pyhsz's biggest trade-off: the sheet doesn't state a battery capacity, so the "three extra charges" figure you get with Yitonglian isn't something you can compare directly — and neither the earbuds nor a Type-C cable are included.
• Who each is for: Yitonglian for the buyer who wants maximum stated reserve power and a one-button pairing routine; Pyhsz for the buyer who wants a wireless charging pad option, faster auto-connect behavior, and warranty coverage.
The Yitonglian case is built around one idea: keep your AirPods 4 running as long as possible. Its 450mAh cell is stated to deliver up to three additional full charges for your earbuds, which is the kind of reserve that matters if you're someone who forgets to plug in at night. The sheet also claims a quick top-up: about 30 minutes to bring the earbuds to 100%, with the case itself refilling in roughly 2.5 hours. That combination — big reserve, short top-up — is the case's whole personality.
The second half of the story is simplicity. Pairing is done with a one-touch button, after which your phone recognizes the case and shows its battery status. There's a clear LED power indicator so you can see how much capacity is left without opening your phone. Physically it's a white plastic hard-shell case, and the compatibility list is narrow and specific: AirPods 4th generation only, models A3053/A3050/A3054/A3056/A3057. The sheet explicitly rules out 1st, 2nd, 3rd generation and Pro models.
Who should buy it: the AirPods 4 owner who treats the case as a power bank first — long trips, back-to-back meetings, days where you're away from a wall outlet. Who should skip it: anyone who wants to drop the case on a wireless charging pad, and anyone who wants the pairing to happen automatically the moment they lift the lid. With Yitonglian you press the button; that's the ritual.
Pyhsz takes the opposite approach: fewer claims about raw capacity, more about convenience and coverage. The headline feature is two charging options — the case accepts both Type-C and wireless charging. If you already keep a Qi pad on your desk or nightstand, that's the difference between "find the cable" and "just set it down." Note the sheet's own caveat: earbuds and the Type-C cable are not included, so you're supplying the cable.
Pairing is where Pyhsz leans in. It uses an upgraded Bluetooth chip for a faster, more stable connection, and after the initial pairing it behaves the way people expect: open the lid, pick up the earbuds, and they connect automatically. No button press each time. Fast charging is also spelled out in concrete terms — 5 minutes of charging gives about 1 hour of listening, and a fully drained pair of earbuds reaches full charge in 30 minutes. The case itself takes 2.5 hours to charge, same as the Yitonglian. There's a clear LED power indicator here too.
Two other details stand out. The sheet describes it as a lightweight hard-shell case, and it carries a 2 Year Warranty — the only warranty listed on either sheet. Compatibility is identical to Yitonglian's: AirPods 4th gen only, models A3053/A3050/A3054/A3056/A3057, not compatible with earlier generations or Pro.
Who should buy it: the AirPods 4 owner who lives near a wireless charger, values auto-reconnect, and likes the idea of two years of coverage. Who should skip it: anyone who specifically wants the largest stated reserve capacity, since no mAh figure is given here.
• Best for stated battery reserve → Yitonglian Charger Case Replacement. A 450mAh cell and up to three extra full charges is the only capacity figure on either sheet.
• Best for charging flexibility → Pyhsz Charging Case Replacement. Type-C and wireless both work; Yitonglian's sheet lists cable charging only.
• Best for fast top-ups on a dead pair → effectively a tie. Both state roughly 30 minutes to fully charge drained earbuds.
• Best for quick partial charges → Pyhsz Charging Case Replacement. Five minutes for about an hour of listening is a specific, useful number for a rushed morning.
• Best for pairing convenience → Pyhsz Charging Case Replacement. Auto-connect on lid-open beats pressing a button each time.
• Best for a one-button, status-at-a-glance routine → Yitonglian Charger Case Replacement. Press to pair, LED shows remaining capacity.
• Best for warranty coverage → Pyhsz Charging Case Replacement. A 2 Year Warranty is listed; nothing comparable appears for Yitonglian.
• Best for a desk-side wireless pad setup → Pyhsz Charging Case Replacement. Drop-and-charge only exists on the Pyhsz side.
• Best for a plain, no-frills replacement → either. Both are white hard-shell cases for AirPods 4 only, and both cover the same model numbers.
My Verdict
No. The sheet states it fits AirPods 4th generation only — models A3053, A3050, A3054, A3056, A3055, A3057 — and is not compatible with 1st, 2nd, 3rd generation or Pro models.
Yes. Pyhsz supports both Type-C and wireless charging. Just remember the sheet notes that earbuds and the Type-C cable are not included, so you'll need your own cable for wired charging.
On paper they match. Both state about 30 minutes to fully charge drained earbuds and about 2.5 hours to charge the case itself. Pyhsz additionally states 5 minutes of charging yields roughly 1 hour of listening.
Prices change often and neither sheet lists one, so I'd check the current price on Amazon using the button on this page before deciding. Let the features — battery reserve, wireless charging, pairing style, warranty — drive the call.
