The Anker Prime 737 (model A1368, formerly branded PowerCore 737 / PowerCore 24K) is Anker’s flagship high-capacity power bank. With a 98% positive rate across 20,000+ verified JD.com reviews, it’s one of the most trusted portable power solutions for laptop users in China. At ¥397.9, it’s also one of the more expensive options — so we dug into what real buyers are saying to see if it lives up to the hype.

Design and Build Quality

The Prime 737 follows Anker’s signature design language — a dark gray rectangular body wrapped in a textured matte finish that repels fingerprints admirably. At 160 × 81 × 27mm, it’s roughly the size of a large smartphone but noticeably thicker. The 640g weight is substantial, but that’s the trade-off for 24,000mAh of capacity using high-quality 21700 cells.

The standout design feature is the intelligent digital display on the front panel. Unlike traditional 4-LED indicators that offer only rough estimates, this screen shows remaining capacity as a percentage and even displays real-time charging wattage during use. A single press of the power button wakes the display and initiates charging.

The port arrangement sits on the top edge: two USB-C ports (140W and 20W) and two USB-A ports (18W each). Port spacing is generous enough for chunky cables, and each port is clearly labeled. The included 60W USB-C cable is a thoughtful touch, though you’ll need a 140W-capable cable to unlock the full charging potential.

Anker’s build quality is evident throughout — the chassis is rigid with no flex, the power button has a satisfying click, and the matte coating feels premium. The 86.4Wh capacity means it’s under the 100Wh limit for airline carry-on, making it one of the most capable travel companions available.

Charging Performance

Single-Device Output

The Prime 737’s party trick is its true 140W USB-C output — a rarity at this price point. Here’s how it performs with real devices:

• MacBook Pro 16” (M4 Max) — 0–50% in 30 minutes at full 140W
• MacBook Pro 14” (M4) — 0–50% in 28 minutes
• MacBook Air M4 — 0–50% in 25 minutes
• iPad Pro 13” — 0–50% in 28 minutes
• iPhone 16 Pro Max — 0–100% approximately 4 full charges
• Nintendo Switch — 2.5 full charges, including TV mode support

Multi-Device Charging

The Prime 737’s PowerIQ 4.0 intelligently allocates power across connected devices. A typical hotel-night scenario:

• MacBook Pro pulls 100W from USB-C1
• iPhone charges at 20W from USB-C2
• AirPods charge at 18W from USB-A All three devices charge simultaneously without bottlenecking.

Self-Charging

• With 65W PD charger — 0–100% in approximately 2 hours
• With 30W PD charger — 0–100% in approximately 3.5 hours

The 65W input means you can top up the entire 86.4Wh battery from dead flat to full during a business lunch. This is notably faster than the 30W input found on many similarly-priced competitors.

Real-World Capacity

Accounting for typical USB-C conversion efficiency of ~90%, the Prime 737 delivers approximately 22,000mAh at 5V — excellent efficiency for a power bank of this capacity class.

Competitor Comparison

vs UGREEN 100W 20,000mAh Power Bank

The UGREEN 100W power bank offers 100W single-port output and 20,000mAh capacity at approximately ¥259–299 on JD.com (~$36–41). It costs significantly less than the Anker Prime 737 at ¥397.9.

Key differences: The UGREEN delivers 100W on its USB-C1 port — sufficient for most laptops except the MacBook Pro 16” at full speed. Its 20,000mAh capacity is 4,000mAh less than the Anker. The build quality and warranty are solid (18 months), but it lacks the Prime 737’s digital wattage display and true 140W single-port capability.

Verdict: For users with a MacBook Pro 16” or anyone who wants maximum single-port charging speed, the Anker is the only choice. For users with a MacBook Air, iPad Pro, or standard ultrabook, the UGREEN offers excellent value at ¥100+ less.

vs Xiaomi 50W 20,000mAh Power Bank

The Xiaomi 50W power bank (PB2050ZM) is priced at ¥199 on JD.com, making it less than half the Anker’s price. It supports 50W single-port output and 20,000mAh capacity with triple ports (2 USB-C + 1 USB-A).

Key differences: The Xiaomi caps at 50W — enough to charge a MacBook Air or standard ultrabook, but half the speed of the Anker when charging larger laptops. However, it offers exceptional protocol compatibility (PD 3.0, QC 4+, PPS) and has a 97% positive rate from 50,000+ JD reviews. It’s also significantly lighter and more pocketable.

Verdict: The Xiaomi 50W is the best value in the budget-to-midrange segment. If you don’t need 140W laptop charging, it delivers 90% of the utility at 50% of the price. The Anker is only worth the premium if you specifically need 100W+ charging.

What Real Buyers Say — JD.com Reviews

We analyzed 20,000+ verified JD.com reviews and translated the most representative ones below. All reviews are from verified purchasers at Anker JD自营旗舰店.

Review #1 — User “C*O” (Recent)**

“The Anker 737 power bank is really worth every yuan. The 24,000mAh capacity can charge my iPhone 15 Pro Max more than 4 times with power left over, and it charges my MacBook Air about 1.5 times. The 140W bidirectional fast charging is incredibly strong — it recharges itself in under an hour. The smart display shows remaining battery and real-time charging wattage, which is super intuitive.”

Key takeaway: Real-world capacity exceeds expectations for multi-device users. The smart display is a standout feature appreciated by actual owners.

Review #2 — User “旅*者” (Recent)**

“A business travel essential! One power bank solved all my charging needs — phone + laptop + earbuds simultaneously. No problem taking it on a plane (it complies with aviation regulations). The build quality is Anker’s usual high standard, with a matte finish that doesn’t attract fingerprints. The only downside: it’s a bit heavy, but that’s expected for 24,000mAh.”

Key takeaway: Airline-compatible and multi-device charging are top selling points for business travelers. Weight is the most commonly cited trade-off.

Review #3 — User “数*控” (Recent)**

“Used with Anker’s 140W charger, the self-charging speed is extremely fast. All three ports can output simultaneously — when I’m on a business trip I plug in the charger and phone before bed, and everything is fully charged by morning. The screen shows real-time power output, and this design feature is incredibly practical.”

Key takeaway: The overnight charging workflow (charge the bank + devices together) is a popular use case. Real-time power display gets consistent praise.

Review #4 — User “g*e” (Recent)**

“The most expensive power bank I’ve ever bought, but also the best. It even supports Nintendo Switch TV mode — that was a pleasant surprise. The build quality and feel are top-tier. The price is certainly high though, and if you’re on a budget you might want to consider other brands.”

Key takeaway: Switch TV mode support is an unexpected bonus. Even satisfied users acknowledge the premium pricing.

What Real Buyers Say — Xiaohongshu Notes

Xiaohongshu (Little Red Book) is China’s premier lifestyle and product discovery platform, where 200+ users have shared detailed real-world experiences with the Prime 737.

“The Anker Prime 737 might be the most powerful power bank currently available. 140W bidirectional fast charging, 24,000mAh massive capacity, a smart digital display that shows everything, and the aesthetics are absolutely on point. My real-world test: charged my MacBook Pro from 20% to 65% in just 30 minutes. It’s a must-have for frequent business travelers. The only downsides: the price stings a bit, and it is heavy.”

— Source: Xiaohongshu, user post (数码产品爱好者)

Key takeaway: Flagship status acknowledged by power users. 30-minute charging test from 20% to 65% is a compelling real-world benchmark.

Xiaohongshu Note #2 — User “效率控阿泽”

“I went all-in and bought the Anker 737. To be honest, you get what you pay for: 1) 140W can even charge gaming laptops, 2) the smart display shows real-time wattage, 3) aviation-grade cells are safe and reassuring, 4) all three ports output simultaneously without throttling. If your budget allows, just go for this one — you won’t need to upgrade later.”

Key takeaway: The “buy once, cry once” philosophy resonates with Xiaohongshu users. Multi-port performance without throttling is a key differentiator.

Common Themes from 20,000+ Reviews

What Users Love ❤️

• True 140W single-port output — repeatedly validated by users and tech reviewers (Chongdiantou confirmed)
• Smart digital display — the percentage + real-time wattage readout is consistently praised as more useful than traditional LED indicators
• 65W fast self-recharge — full charge in about 2 hours is a game-changer for frequent travelers
• Four-port versatility — 2C + 2A arrangement covers virtually every device scenario
• Premium build quality — Anker’s reputation for solid construction is upheld
• Airline-safe design — 86.4Wh slides under the 100Wh aviation limit

Common Criticisms 💢

• Weight (640g) — the most frequent complaint; it’s heavy by any standard
• Price (¥397.9) — consistently described as expensive, even by satisfied users
• Form factor — large and not pocket-friendly; designed for bags, not pockets
• C2 and A ports limited — USB-C2 caps at 20W, USB-A at 18W, which feels modest compared to the flagship C1
• No wireless charging — no Qi or MagSafe support, disappointing for some
• Self-charge via C2 only — C1 is output-only, a minor but notable oddity

Who Should Buy

• MacBook Pro 16” users — if you need full-speed 140W charging on the go, this is one of the very few power banks that delivers it
• Creative professionals — photographers, videographers, and developers who carry multiple devices and need reliable on-the-go power
• Frequent business travelers — hotel overnight charging, airport lounges, and carry-on compliance make this an ideal travel companion
• Tech enthusiasts — the most capable power bank in its class, with features (smart display, 140W, 2C+2A) that justify the premium
• Nintendo Switch gamers — TV mode support is a unique bonus

Who Should Skip

• Phone-only users — 640g is excessive for topping up a phone; look at 10,000mAh options
• Budget-conscious shoppers — the Xiaomi 50W offers excellent performance at half the price
• Midrange needs — if you charge a MacBook Air or standard ultrabook, the UGREEN 100W covers you at a better price
• EDC pocket carriers — this lives in a bag, not a pocket
• MagSafe fans — no wireless charging means extra cables
• Light travelers — Anker’s smaller PowerCore 10K series is more appropriate

Buying Advice

Check JD.com pricing regularly. The Anker Prime 737’s ¥397.9 price fluctuates during promotional events (618, Singles’ Day, New Year sales), where it has been seen as low as ¥349. The 24-month warranty from Anker’s JD self-operated store provides peace of mind, and the included 60W cable saves you an immediate accessory purchase.

Pair with a 65W+ USB-C charger to unlock the fast 2-hour self-charge time. Using a standard 18W phone charger results in a 6+ hour recharge — a poor experience for a premium product.

Consider the ecosystem angle. If you already own Anker chargers and cables, the consistent charging experience across your gear adds real convenience. If you’re brand-agnostic, the UGREEN or Xiaomi alternatives deliver strong performance at lower prices.

FAQ

Can I take the Anker Prime 737 on a plane?

Yes. At 86.4Wh, it falls under the 100Wh limit imposed by CAAC, FAA, EASA, and IATA for carry-on lithium batteries. It must be carried in cabin baggage, not checked luggage.

Is the 140W port bidirectional?

No. USB-C1 is output-only for the full 140W. You must use USB-C2 (20W) for charging the power bank itself. This is a common point of confusion.

Does it support PPS for Samsung fast charging?

USB-C1 (140W) supports PPS. Samsung 25W Super Fast Charging works fully. Samsung 45W Super Fast Charging 2.0 (PPS 3.3–20V) is not supported.

How long will the battery last?

The 21700 lithium-ion cells are rated for approximately 500 charge cycles before capacity degrades to 80%. With weekly full cycles, expect 8–10 years of useful service.

Can it charge a Nintendo Switch in docked/TV mode?

Yes — verified by multiple JD buyers. The 140W output supports Switch docked mode, which many lower-power banks cannot sustain.

What’s included in the box?

The Prime 737 ships with a 60W USB-C to USB-C cable and documentation. A wall charger is not included — purchase separately or use an existing PD charger.
