TOPTAI 25W Wireless Charger Test: Charging Results Across Six iPhone Models

Six iPhone Models, Charging Times at a Glance

For a brand or importer choosing a 25W wireless charger, the most useful starting point is the phone your customer actually uses. TOPTAI uses a split boost-module charging solution, and the supplied platform test records cover iPhone 17, iPhone 16, iPhone 15, iPhone 14 Plus, iPhone 13 and iPhone 12. These results give your purchasing team a concrete basis for selecting a product and an adapter combination for sampling.

The report lists 1 hour 50 minutes for iPhone 17 and 1 hour 55 minutes for iPhone 16 with a PPS adapter. Across the ten recorded setups, reported full-charge times range from 1 hour 50 minutes to 2 hours 10 minutes. The summary table lists a room temperature of 26°C for every setup.

These are the full-charge times reported for the individual test setups, not averages or guaranteed times for every finished product. The records do not establish the same 25W received power across all six phones. They also do not specify a common starting battery percentage, battery health, software version or repeat-test count. Use the results to shortlist a configuration, then confirm it on your target devices.

The Split Boost-Module Platform Behind Our 25W Chargers

The module below is the platform shown in the supplied report. It is part of the split boost-module solution used in our 25W wireless charger offering. For buyers, the commercial decision is the finished charger: its charging format, housing, adapter, branding and suitability for the intended sales channel.

When discussing a custom 25W wireless charger with TOPTAI, tell us whether your project needs a compact pad, a desk product or another available format. We can match the project to a suitable platform and identify what needs to be checked on the selected sample. A module-level test is a useful starting point, but housing, alignment and the supplied adapter remain part of the finished-product evaluation.

For an existing product with logo and packaging customization, the sample review can focus on your chosen configuration and customer devices. Projects involving a different structure or charging arrangement require a separate feasibility review. The testing scope should follow the product you intend to sell.

iPhone 17 and iPhone 16: Results for Newer-Model Product Ranges

If your brand is building a range around newer iPhone users, begin with the iPhone 17 and iPhone 16 records. The PPS results show reported full-charge times below two hours for both tested phones. That is a concrete performance reference to review alongside product format, retail presentation and your target purchase price.

iPhone 17: 1 Hour 50 Minutes with a PPS Adapter

The iPhone 17 curve provides the lead result for this platform. It shows the charging session progressing through different operating levels rather than holding one constant level throughout. For a buyer planning a 25W product, ask for the same target phone to be tested with the exact adapter and finished sample you plan to order.

iPhone 16: 1 Hour 55 Minutes with a PPS Adapter

The iPhone 16 record adds a second device reference for your assortment. Its reported time is five minutes longer than the iPhone 17 result in this report. Treat those as separate recorded sessions rather than a universal ranking between the phones. Battery condition and test setup should be aligned before making a customer-facing comparison.

For a launch focused on these devices, send TOPTAI the exact phone variants your customers use. The report names iPhone 17 and iPhone 16; it does not provide separate results for every Pro, Pro Max or Plus variant. Sampling should cover the variants that matter to your channel.

iPhone 15, 14 Plus, 13 and 12: Results for a Broader Customer Base

A distributor or private-label brand may need to serve customers using several generations of iPhone. These four additional PPS records help you review that wider device mix without assuming that a newer-model result applies to every older phone. The tested model is iPhone 14 Plus, specifically, rather than the full iPhone 14 family.

iPhone 15: 2h 10m with PPS

iPhone 14 Plus: 2h 06m with PPS

iPhone 13: 2h 00m with PPS

iPhone 12: 2h 10m with PPS

For a mixed-generation range, use this group to define your sample checklist and compatibility wording. Select representative devices from your actual customer base and agree on the performance you need before approving packaging. A clear list of tested phones is more useful to your sales team than an unsupported promise covering every iPhone.

The voltage and current traces include visible transitions and fluctuations. We retain those features in the charts. They should not be presented as proof of uninterrupted 25W charging or as a completed reliability qualification. Full-charge time and repeated finished-product testing answer different purchasing questions.

PPS or 12V? Match the Adapter to Your Product Bundle

The report also includes 12V-adapter tests for iPhone 15, iPhone 14 Plus, iPhone 13 and iPhone 12. These are useful when deciding whether to offer a charger alone or a charger-and-adapter bundle. A power-adapter choice should be validated with the device mix you intend to support.

In these records, iPhone 15 has the same reported time with both adapter types. The 12V records are 16 minutes shorter for iPhone 14 Plus, 10 minutes shorter for iPhone 13 and six minutes shorter for iPhone 12. This does not establish that 12V is always faster: the report does not document a controlled, repeated comparison with matched starting conditions. It does show why your adapter decision deserves a sample test.

For a bundled product, approve the charger and adapter together and carry that combination through the purchase specification. For a charger sold separately, agree on clear input and adapter instructions. That helps your customer choose the right setup and gives your support team a consistent reference.

Which TOPTAI 25W Wireless Charging Option Fits Your Business?

Brands Targeting Newer iPhone Users

Start with the iPhone 17 and iPhone 16 PPS records, then evaluate the product format and retail presentation that fit your brand. Ask for a finished sample with the intended adapter. Use the approved sample results to decide which charging-time claims belong on your product page.

Wholesalers Serving Several Phone Generations

Start with the six-model summary and identify the phones most common among your downstream customers. A focused compatibility list and a confirmed adapter configuration can make the product easier to specify and sell. Include any additional high-volume models in the sample plan rather than assuming coverage from a related model name.

Specialist Brands and Value-Focused Product Programs

If your sales channel does not require a specific Qi2 25W certification, consider our performance-focused 25W route. Compare verified charging behavior, the finished product’s quality, customization scope and quoted cost against your customer’s needs. The report supports a performance discussion; pricing and production reliability need their own project review.

Programs with Certification Requirements

If your retailer or accessory program requires Qi2 25W certification, select a model with the required verified certification. A 25W performance claim is not a substitute for that requirement. TOPTAI can help you compare available routes before samples and packaging are finalized.

Request a Sample for Your Target Phones

Bring us the phone list and the business brief. We can use the recorded results as a starting point, recommend a suitable 25W wireless charging option and define the checks for your selected sample. Before bulk production, agree on the product configuration, branding, adapter, acceptance criteria and applicable market requirements.

• Target phone models and the cases your customers typically use.
• Sales countries, channel and any required product certifications.
• Preferred charger format and whether an adapter is included.
• Estimated order quantity, target price and launch timing.
• Logo, color, packaging and instruction requirements.
• Charging-time expectations and sample checks you need.

MOQ, sample timing and production lead time depend on the selected model and customization scope. Ask for a project-specific quotation rather than treating a platform test as a universal product specification. Your next step is to choose the configuration that fits your market and validate it on the phones your customers use.
