iPhone Semi-Solid State Battery Case: A Safer-by-Design Alternative for Wholesale Buyers

What Is a Semi-Solid State Battery Case?

A semi-solid state battery case combines an iPhone protective case, a wireless charger and a power bank in one product. What sets it apart from most battery cases is the cell: instead of a free-flowing liquid electrolyte it uses a gel or semi-solid electrolyte, which leaves less free liquid inside the cell and is designed to resist leakage and swelling when the case is pressed, bent or dropped.

Why Buyers Choose Semi-Solid Over Standard Lithium-Polymer Cases

• Safer by design: a gel-type electrolyte is built to tolerate mechanical stress better than a liquid one — a concern for returns and liability in strict battery-safety markets such as the EU and US.
• Longer cycle life: the cell is rated for 3000+ charge cycles with 80%+ capacity retention (cell supplier rating), against the 300–500 cycles typical of ordinary battery cases.
• Stable under heat: designed to hold capacity in warm conditions; for the phone’s own protection, wireless output steps down from 15W to 7.5W above 45 °C surface temperature.

Three Capacity Series on One Platform

The range is built on one shell platform so you can serve different price points from the same fitment list. The product page lists every SKU; the key differences are below.

Series	Printed	Measured	Thickness	Net weight	Charge added (iPhone 17)
Slim 2500	2,500 mAh (3,000 on Pro Max)	2,100 mAh (2,600 on Pro Max)	15.5 mm	93–95 g (115 g Pro Max)	≈ +32%
Max 3600	3,600 mAh	3,500 mAh	~16.5 mm	~105 g	≈ +55%
Pro 5000	5,000 mAh	4,500 mAh	17.5 mm	108 g	≈ +70%

Printed capacity is the figure marked on the case and gift box; measured capacity is what the pack delivers under standard conditions. We state both, which makes true-capacity labelling for EU GPSR and US FTC straightforward. For a deeper comparison, read our capacity guide: Slim 2500 vs Max 3600 vs Pro 5000.

Certifications and Transport Compliance

The product comes with 3C, CE, FCC and RoHS documentation and full MSDS / SDS. Cells come from UN 38.3 and IEC 62133 certified suppliers, and a UN 38.3 test summary plus 1.2 m drop and stacking reports are available for sea and air freight. The case ships as a lithium-ion battery contained in equipment (IATA PI 967 or the equivalent sea provisions) and we support the DG paperwork. Airline carry-on rules vary by carrier and route, so check your own channel’s requirements — see our shipping and logistics guide and electronics import compliance guide.
