Benks PowerGo Magnetic Wireless Power Bank Review: 10000mAh MagSafe

Benks PowerGo magnetic power bank has 15,000+ reviews on JD.com with a 4.3/5 rating at ¥129 ($18). Users appreciate the strong N52 magnet array that securely holds iPhones, the slim 10000mAh design that’s barely larger than the phone itself, and the dual charging (wireless + wired USB-C). The main complaints are the 7.5W iPhone wireless charging speed (slower than Apple’s 15W MagSafe) and the power bank heating up noticeably during wireless charging. Conclusion: ✅ Worth Buying — a compact and convenient MagSafe battery pack for iPhone users who want emergency top-ups without cables.

Introduction

Benks PowerGo is positioned as a premium MagSafe battery pack for iPhone users. Unlike many magnetic power banks that are bulky or have weak magnets, the PowerGo uses N52 neodymium magnets for strong attachment and features a slim form factor that’s close to the phone’s dimensions.

At ¥129 ($18), it competes directly with the Anker 621 MagGo (¥179) and ESR HaloLock power bank (¥99). With 15,000+ reviews and a 4.3/5 rating on JD.com, it’s a solid mid-range option in the growing MagSafe power bank category.

Design and Build Quality

The PowerGo is a rectangular battery pack with a soft-touch matte finish. The front panel has a circular MagSafe charging pad with a raised rim that centers the phone. A small LED display on the side shows remaining battery percentage — a useful feature that’s surprisingly absent on many competitors.

The N52 magnets hold iPhones securely. You can hold the phone by the power bank and shake it moderately without the phone detaching. The size is well-matched to iPhone Pro models — slightly wider and taller than the phone but not excessively so.

The USB-C port supports 20W PD input/output. You can charge both the power bank and your phone simultaneously through the wired connection while also charging wirelessly at the same time — useful for charging two devices at once.

“The build quality is excellent — the soft-touch finish feels premium and the LED battery indicator is really useful. I can see exactly how much charge I have without guessing. The size is perfect for my iPhone 16 Pro — it’s like a slightly thicker phone case. At 195g, it’s noticeable but not heavy.” — JD.com user, verified purchase

Performance

The 7.5W wireless charging for iPhone is the main compromise. Apple restricts third-party MagSafe chargers to 7.5W (Qi standard), while Apple’s own MagSafe charges at 15W. This means the PowerGo charges your iPhone at about half the speed of Apple’s official MagSafe battery pack.

In practice, 7.5W is sufficient for emergency top-ups. You get about 50% charge in 2 hours for an iPhone 16 Pro — adequate for extending battery life during a day out but not a fast charging solution.

The 20W USB-C wired charging is faster. Using the cable, an iPhone 16 Pro charges from 20% to 80% in about 45 minutes. For faster charging, use the wired connection.

The power bank does heat up during wireless charging. The thermoelectric effect causes both the battery pack and the phone to get warm. This is normal but can be uncomfortable if you hold the phone while it’s charging wirelessly.

“The wireless charging is convenient but slow. I use it overnight or when I’m at my desk. When I need a quick charge before heading out, I plug in the USB-C cable for fast 20W charging. The combination of wireless convenience and wired speed is what makes this versatile.” — JD.com user

User Reviews by Theme

Magnetic Strength

“The magnet is strong enough that I can pick up my phone by the power bank and shake it. No separation at all. This was my biggest concern with MagSafe power banks and the Benks exceeded my expectations. The alignment is also perfect — no fiddling to find the sweet spot.” — JD.com user

💡 Summary: N52 magnets provide class-leading attachment strength — the power bank stays firmly connected to the phone.

Charging Speed Limitations

“7.5W wireless charging is slow. I knew this before buying but it’s still frustrating. It takes about 3 hours to charge my iPhone 16 Pro from 20% to 100% wirelessly. Using the cable, it takes under 2 hours. The wireless is for convenience, not speed.” — JD.com user

💡 Summary: The 7.5W Qi limitation is Apple-imposed and affects all third-party MagSafe power banks — not a Benks-specific issue.

Heating During Wireless Charging

“After 30 minutes of wireless charging, both the power bank and my phone get noticeably warm. Not dangerously hot, but warm enough that I don’t want to hold the phone. I only use wireless charging when the phone is on my desk or nightstand.” — SMZDM user

💡 Summary: Heat generation is the main comfort downside of wireless charging — best used with the phone stationary.

Battery Percentage Display

“The LED percentage display is the best feature of this power bank. My previous power bank had 4 LED dots that told me nothing specific. Knowing I have exactly 73% left is much more useful. This should be standard on all power banks.” — JD.com user

💡 Summary: The percentage display is a standout feature that provides precise battery information at a glance.

Value for Money

“Compared to the Anker 621 which costs ¥179 for only 5000mAh, the Benks PowerGo at ¥129 for 10000mAh is clearly better value. The Anker is smaller and lighter, but half the capacity for more money doesn’t make sense to me.” — JD.com user

💡 Summary: Excellent capacity-to-price ratio — double the capacity of the similarly-priced Anker alternative.

Purchase Recommendations

✅ Worth Buying (¥129)

Best value MagSafe power bank for iPhone users who want 10000mAh capacity at a reasonable price. The strong magnets and percentage display make it a well-designed daily companion.

💰 Premium Pick: Anker 621 MagGo (¥179)

If portability matters more than capacity, the Anker 621 is smaller and lighter (140g vs 195g) with a better build reputation. But you pay ¥50 more for half the battery.

⚠️ Budget Warning: Not a Fast Charger

The 7.5W wireless charging is slow. If you need fast wireless charging, you need Apple’s official MagSafe battery pack or a certified 15W MagSafe power bank, which costs significantly more.

FAQ

Q: Does the Benks PowerGo charge iPhone at 15W MagSafe? A: No. Apple limits third-party MagSafe accessories to 7.5W wireless charging (Qi standard). Only Apple-certified MagSafe battery packs can charge iPhones at 15W. This applies to all third-party MagSafe power banks.

Q: How much charge does the PowerGo give an iPhone 16 Pro? A: The 10000mAh capacity provides approximately 1.8 full charges for an iPhone 16 Pro (3350mAh battery). Real-world capacity accounts for conversion efficiency, so expect about 1.5-1.7 charges.

Q: Can I charge the power bank and my phone at the same time? A: Yes. The PowerGo supports pass-through charging. Plug the USB-C port into a charger, and it will charge both the power bank and your phone wirelessly simultaneously.

Q: Is the power bank compatible with iPhone 12/13/14/15 cases? A: Yes, as long as the case is MagSafe-compatible or has a magnetic ring. Cases thicker than 3mm may reduce magnetic hold strength. Thin cases (under 2mm) work best.

Q: Does the PowerGo support charging two phones at once? A: Yes. You can charge one phone wirelessly on the MagSafe pad and another via the USB-C cable simultaneously (wired 20W + wireless 7.5W).
