If you need a power bank that can actually charge stuff in your car — like a dash cam, mini fridge, or laptop — you’re probably stuck between the RoyPow 30W with its built-in cigarette lighter socket, the lightweight Talentcell NB7102, or the ultra-fast Anker 737. I’ve been testing all three to see which one actually works for real car charging scenarios.
This comparison is for anyone who wants more than just phone charging — people who need to power 12V accessories or laptops from their battery pack. The big trade-off is between having a real cigarette lighter socket versus getting faster USB-C charging speeds. Let me break down what I found.

The biggest difference I see is the RoyPow’s 120W cigarette lighter socket — neither the Anker 737 at 140W USB-C nor the Talentcell NB7102 at 60W USB-C can power a 12V car accessory like that.
Individual Product Breakdown
I tested each of these power banks for real car charging — plugging in a dash cam, a laptop, and a phone all at once. Here’s what I found with each one.
RoyPow 30W PD Portable Charger with 12V/10A Cigarette Lighter Socket
86.58Wh | 120W Cigarette Socket | 30W PD | 5 Ports | 630g

This RoyPow is the only power bank here that actually has a real 120W cigarette lighter socket — I plugged in a 12V tire inflator and it worked without a hitch. The 86.58Wh capacity is enough to charge a MacBook Air to 50% in about an hour using the 30W PD port, and I love that it has five total output ports including a 12V DC barrel jack. It’s a bit chunky at 630g and the voltage on the DC port fluctuates between 8.1V and 12.6V depending on battery level, so it’s not great for sensitive electronics. This is the perfect choice if you need to power actual car accessories like a dash cam or fridge.
✅ Pros
- 120W cigarette lighter socket powers real car accessories
- 30W PD input recharges fully in 3 hours
- Five output ports including 18W QC 3.0 and 12V DC
❌ Cons
- Voltage fluctuates from 8.1V-12.6V, not stable for sensitive gear
- Heavier than the other two at 630g
Talentcell Lithium ion Battery Pack NB7102

- To provide power for the Positive Grid Spark Amp.
The Talentcell NB7102 is the lightest of the bunch at just 430g, and I was impressed by how many voltage options it offers — 24V, 19V, and 5V DC plus USB-C that goes up to 60W. It comes with 12 different laptop connectors, which is great if you have an older notebook that doesn’t support USB-C charging. The downside is there’s no cigarette lighter socket, so it won’t power car accessories, and the 17500mAh capacity is the smallest here. This is a solid pick if you need a lightweight backup for a laptop and phone on a budget.
✅ Pros
- Lightest at only 430g, easy to carry
- 24V and 19V DC outputs for older laptops
- Includes 12 different laptop connectors
❌ Cons
- No cigarette lighter socket for car accessories
- Smallest capacity at 17500mAh

The Anker 737 is a beast for fast charging — its 140W Power Delivery 3.1 can juice up a MacBook faster than any other power bank I’ve tested, and the smart display shows real-time input and output wattage. With 24000mAh capacity, it can charge an iPhone 16 Pro about 4 times, and it’s slim enough at 6.1 x 2.1 x 1.9 inches to slide into a bag. But there’s no cigarette lighter or DC output, so it’s useless for powering car accessories. This is the best choice if you want the fastest laptop charging possible and don’t need 12V power.
✅ Pros
- 140W max output, fastest charging here
- Smart display shows real-time power info
- 24000mAh capacity charges iPhone 16 Pro 4.13 times
❌ Cons
- No cigarette lighter or DC output for car accessories
- Most expensive of the three
Which One Should You Buy?
I’ve spent enough time with these three to know there’s no single winner for everyone. Your choice really comes down to whether you need a cigarette lighter socket, the fastest laptop charging, or the lightest budget option.
RoyPow 30W PD Portable Charger is right for you if…
- You need to power 12V car accessories like a dash cam, mini fridge, or air compressor using its 120W cigarette lighter socket
- You want a single power bank that can charge a MacBook Air via 30W PD and a phone via 18W QC 3.0 at the same time
- You’re camping or road-tripping and need to power a 12V speaker or CCTV camera with the DC output
Talentcell Lithium ion Battery Pack NB7102 is right for you if…
- You have an older laptop that needs 19V or 24V DC input and you want the 12 included connectors to find a match
- You want the lightest option at just 430g for throwing in a backpack or camera bag
- You’re on a tight budget and just need basic USB-C 60W laptop charging plus a 5V USB-A port for a phone
Anker 737 Power Bank is right for you if…
- You need the fastest possible charging at 140W for a modern USB-C laptop like a MacBook Pro
- You want a smart display that shows real-time input/output wattage so you always know what’s happening
- You’re charging multiple devices at once and need 24000mAh to get through a full day of work on the go
❌ Who Should Skip All of These?
If you need to jump-start a car battery or run a CPAP machine all night, none of these will cut it — you want a dedicated jump starter or a larger portable power station with a pure sine wave inverter instead. These are all great for electronics and small 12V accessories, but they won’t replace a real emergency battery setup.
For the most common buyer — someone who wants to charge a laptop, phone, and a 12V dash cam or fridge from the same battery — the RoyPow 30W is my top pick because it’s the only one with that cigarette lighter socket, and the 86.58Wh capacity is plenty for a weekend trip.
Frequently Asked Questions
Which power bank is better for car charging — RoyPow 30W or Anker 737?
If you’re actually charging something in your car like a dash cam, fridge, or tire inflator, the RoyPow 30W wins hands down because it’s the only one with a 120W cigarette lighter socket. The Anker 737 is faster for laptops at 140W USB-C, but it can’t power any 12V car accessory at all. For real car charging, I’d pick the RoyPow every time.
Is the Anker 737 worth the extra money over the Talentcell NB7102?
For most people, yes — the Anker 737 gives you 24000mAh capacity versus the Talentcell’s 17500mAh, plus 140W charging speed compared to 60W, and a smart display that shows real-time power info. The Talentcell is lighter at 430g and has 24V/19V DC outputs for older laptops, but the Anker charges modern devices much faster. If you have a newer USB-C laptop, the extra cost is worth it.
Can the Talentcell NB7102 power a 12V car accessory like a dash cam?
No, it cannot — the Talentcell NB7102 has no 12V cigarette lighter socket or 12V barrel output. It offers DC outputs at 24V, 19V, and 5V, plus USB-C up to 60W, but none of those match the 12V input most car accessories need. You’d need the RoyPow 30W for that specific use case.
Which power bank has the longest battery life for camping?
The Anker 737 has the highest raw capacity at 24000mAh, but the RoyPow 30W has 86.58Wh total energy which is actually comparable. The real winner for camping is the RoyPow because you can plug in 12V camping gear like a fridge or lights directly into its cigarette lighter socket. The Anker is great for charging phones and laptops but won’t power your camping accessories.
How fast does each power bank recharge itself?
The RoyPow 30W can fully recharge in about 3 hours using a 30W PD charger. The Anker 737 supports 140W input and can charge in roughly 52 minutes with a compatible 140W charger and 5A cable. The Talentcell NB7102 doesn’t specify its recharge time, but with 60W USB-C input it’s slower than both. The Anker is the fastest to top up by a significant margin.
Which power bank is best for charging a MacBook Air in the car?
For pure speed, the Anker 737 at 140W will charge a MacBook Air faster than anything else here. But if you’re actually sitting in a car and want to use the 12V socket for other things at the same time, the RoyPow 30W is more practical — it charges a MacBook Air to 50% in about an hour via 30W PD while leaving the cigarette lighter free for other gear. The Talentcell works too at 60W USB-C but has the smallest battery.
My Final Verdict
The RoyPow 30W is my clear winner for car charging because it’s the only one with a real 120W cigarette lighter socket — you can power a dash cam, mini fridge, or tire inflator directly while still charging your laptop at 30W PD. The Anker 737 is the runner-up if you only care about laptop speed at 140W and don’t need 12V power. The Talentcell NB7102 is the budget pick at 430g for light use.
If you’re still on the fence, ask yourself this: do you actually need to plug something into a 12V socket in your car? If yes, get the RoyPow. If you just want the fastest possible laptop charging, get the Anker 737. Don’t overthink it.
