45W GaN Charger Manufacturer
Ultra-thin 45W GaN chargers with interchangeable plugs, built in our own factory in Dongguan since 2009. Two models, five plug regions, MOQ 500.
The sweet spot for phones, tablets and ultrabooks
A 45W GaN charger sits right between compact phone chargers and bulky laptop bricks. It charges an iPhone to 50 % in about 25 minutes, keeps a MacBook Air running while topping it up, and still fits in a shirt pocket. For distributors and private-label brands, the 45W segment is the fastest-growing GaN tier in Europe and the Middle East: buyers want one charger for everything they carry, and 45W covers the vast majority of devices.
Phones and tablets
iPhone 16 to 50 % in ~25 min. Samsung Galaxy S25 to 50 % in ~22 min via PPS. iPad Air, Pixel, OnePlus — all capped well below 45W, so the charger always has headroom.
Ultrabooks
MacBook Air (any M-series), Dell XPS 13, HP EliteBook 840, Lenovo ThinkPad X1 Carbon — all ship with a 30W or 45W adapter. The CB 45W replaces them all in a fraction of the size.
Gaming handhelds
Nintendo Switch (OLED), Steam Deck, ROG Ally — 45W is enough to charge them at full speed while playing.
45W GaN Charger Manufacturer — Two Ultra-Thin Designs

One charger, five plug regions
The CB ultra-thin series uses a click-on plug adapter that slides into the back of the charger and locks with a firm click. Stock one SKU and ship to the US, EU, UK, Australia or China by swapping the adapter — no separate model for each country. For distributors carrying multiple regions this cuts inventory in half; for Amazon sellers it means one ASIN with a travel-kit bundle.

45W vs 30W vs 65W: which wattage do your buyers need?
Choosing the right wattage saves your customers money and reduces returns. Here is how the three most popular tiers compare for everyday devices.
| 30W | 45W | 65W | |
|---|---|---|---|
| Best for | Phones, earbuds, small tablets | Phones, tablets, ultrabooks, gaming handhelds | Phones, tablets, ultrabooks, 15″ laptops |
| MacBook Air (M-series) | Charges slowly | Full-speed charge | Full-speed charge |
| MacBook Pro 14″ | Too slow | Usable (slower) | Full-speed charge |
| iPhone 16 to 50 % | ~30 min | ~25 min | ~25 min (same; phone caps at ~27W) |
| Samsung Galaxy S25 | ~35 min to 50 % | ~22 min to 50 % (PPS) | ~22 min (same; phone caps at ~25W) |
| Nintendo Switch OLED | Charges while docked | Full-speed portable + docked | Same (Switch caps at 39W) |
| Typical size | ~34 × 34 × 35 mm | ~78 × 43 × 14.5 mm (ultra-thin) | ~84 × 45 × 14.6 mm |
| Rongjun model | XFC 30W / XPD-V30 | CB 45W / CB 45W II | 7 models |
For most retail buyers a 45W charger is the best all-round choice: it covers every phone and tablet at full speed, handles ultrabooks, and is noticeably thinner than a 30W cube. If your market skews toward 15-inch laptops or multi-device power users, step up to 65W.
GaN vs silicon: why it matters at 45W
At 30W the size difference between GaN and silicon is modest. At 45W the gap becomes dramatic: a silicon 45W charger is roughly the size of an old MacBook brick, while our GaN CB 45W is thinner than most phones. The Yuantuo YT6508GDB GaN transistor switches at frequencies that a silicon MOSFET cannot reach, allowing smaller magnetics and a slimmer transformer — which is how we achieve a 14.5 mm profile.
| GaN (CB 45W) | Silicon 45W (typical) | |
|---|---|---|
| Volume | ~49 cm³ | ~110 cm³ |
| Thickness | 14.5 mm | 28–32 mm |
| Weight | ~75 g (without adapter) | ~130 g |
| Heat at full load | Warm (well within spec) | Hot to the touch |
| Efficiency | ~92 % | ~84 % |

45W GaN charger — frequently asked questions
What devices can a 45W GaN charger power?
Smartphones (iPhone, Samsung, Pixel, OnePlus), tablets (iPad Air/Pro, Galaxy Tab), ultrabooks (MacBook Air M1–M4, Dell XPS 13, HP EliteBook 840, ThinkPad X1 Carbon), and gaming handhelds (Nintendo Switch OLED, Steam Deck, ROG Ally). The CB 45W uses USB PD 3.0 and PPS, so it negotiates the fastest safe speed for every device.
Is 45W enough for a laptop?
For most 13–14 inch ultrabooks, yes. MacBook Air, Dell XPS 13, HP EliteBook 840 and Lenovo ThinkPad X1 Carbon all ship with 30W or 45W adapters. Heavier 15–16 inch laptops with dedicated GPUs typically need 65W or 100W. Check our 65W or 100W pages for those.
What is the MOQ for OEM 45W GaN chargers?
500 pieces per model with your logo. 300 pieces on request for a first trial. Logo printing has no setup fee, and we provide a free packaging mockup.
What is the difference between the CB 45W and CB 45W II?
Both share the same 45W output, ultra-thin form factor (78 × 43.4 × 14.5 mm) and interchangeable plug system. The CB 45W II has a refined housing with a minimal accent line. Electrically, the two models are identical — pick the design your market prefers.
Which certifications does the 45W charger have?
CCC, CE (LVD + EMC), FCC, RoHS and a UL test report. The full certificate list per model is on our certifications page.
Can I mix plug types within one order?
Yes. The CB ultra-thin series uses interchangeable plug adapters, so you can order a mix of US, EU, UK, AU and CN adapters. This is unique to the CB series — other Rongjun models have a fixed plug per SKU.
What is the lead time for 1,000 pieces?
10–15 working days. 3,000 pieces: 15–20 days. Larger orders are agreed per project. Samples are ready in 3 days.

Yes. The CB 45W is a 45W PPS charger for wholesale, with USB PD up to 45W and PPS from 5 to 11V, from 500 pieces per model.
