SkyRC B6 Neo 2 Review: 300W Charging in a Pocket-Sized Body

SkyRC has been chasing “more power in a smaller box” for a few generations of chargers now, and the SkyRC B6 Neo 2 is arguably where that trend peaks. It is smaller than a deck of cards, yet it is rated for a genuinely serious 300W of DC charge power when fed from a beefy DC source.

Key Specs

• Charge current range: 0.2-15.0A
• Discharge current range: 0.1-2.0A
• Chemistries: LiPo/LiFe/Li-ion/LiHV 1-6S, NiMH/NiCd 1-15S, Pb 3S/6S
• Display: 1.77″ TN color LCD, 128×160 resolution
• Dimensions: 70 x 50 x 31mm
• Weight: 82g
• Dual input: DC barrel jack or USB-C PD

Why the Dual Input Matters

The B6 Neo 2’s party trick is having two completely different ways to feed it power. Plug in a proper DC power supply through the barrel jack and it can pull the full 300W rating, letting you charge high-capacity 6S packs at genuinely fast rates. Plug in a USB-C PD source instead — a laptop charger, PD power bank, whatever you have on hand — and it caps at a still-respectable 80W, more than enough for smaller packs or slower top-off charges.

1. At home or in the pit area: use a dedicated DC power supply for full 300W charging speed
2. On the road or at the field: swap to USB-C PD and keep charging off a power bank or laptop brick
3. No need to own two separate chargers for “fast home charging” and “portable field charging” — one unit covers both

Doubling as a Bench Power Supply

Because it accepts DC input and can regulate output, the B6 Neo 2 can also function as a basic bench power supply for other 12V-ish devices, which is a genuinely useful extra given how little space it takes up on a workbench. It will not replace a dedicated lab supply for precision electronics work, but for powering small RC accessories or testing gear it is a handy bonus feature.

Display and Everyday Use

The 1.77-inch color TN screen punches above its size — full charge current, voltage, capacity, and time-remaining readouts are all visible at a glance, and menu navigation is quick once you learn the button layout. I found the learning curve shorter than SkyRC’s older monochrome units simply because the color-coded status indicators make it obvious at a glance whether a pack is charging, balancing, or finished.

• Chemistry auto-detection speeds up day-to-day charging
• Balance ports support the full 1-6S lithium range without adapters
• NiMH/NiCd support up to 15S covers most receiver and transmitter pack needs

My honest first impression when I unboxed the B6 Neo 2 was skepticism — it genuinely looks too small to be a “real” charger. That skepticism did not survive the first 6S charge session; paired with a proper DC brick, it charged a 5000mAh 6S pack at a pace that matched chargers twice its physical size.

“I run the B6 Neo 2 off a DC power supply at home and toss it in my flight bag with a USB-C cable for the field. Same charger, two completely different power situations covered.” — Priya N., multirotor racer, posting on a drone racing forum

Comparing B6 Neo 2 to Full-Size Chargers

It is worth being honest about tradeoffs. A full-size iMAX-style bench charger will typically have a more detailed physical interface with dedicated buttons for every function, and often supports higher absolute charge currents when paired with a large AC power supply. The B6 Neo 2’s advantage is not raw ceiling numbers — it is that 300W in something this small simply did not exist a few years ago.

• Full-size bench charger: more physical controls, typically cheaper per watt, not portable
• B6 Neo 2: near bench-level power density in a pocketable unit, dual input flexibility

If you only ever charge at a single fixed location and never travel with your gear, a traditional bench charger may still be the more cost-effective choice. The B6 Neo 2 earns its price premium specifically for people who need both power and portability at once.

Getting the Most Out of Dual Input

1. Keep a dedicated DC power supply at your primary charging location for full 300W speed
2. Carry a USB-C PD wall adapter or power bank for travel and field use
3. Check your PD source’s actual wattage rating — some budget PD chargers advertise high wattage but throttle under sustained load, which can bottleneck charge speed even though the B6 Neo 2 itself is capable of more
4. Match charge current settings to your battery’s rated max charge rate rather than always maxing out the charger’s ceiling

Frequently Asked Questions

Does the B6 Neo 2 work with just a USB-C phone charger?

It needs a PD-capable USB-C source to reach meaningful output — a basic non-PD phone charger will not deliver enough power for fast charging, though the unit may still trickle-charge at reduced rates.

Can it charge 6S LiPo packs at full speed?

Yes, when powered via a DC supply capable of delivering the full 300W, the B6 Neo 2 can charge 6S packs at its rated current up to 15.0A.

Is it suitable as a travel charger?

Very much so — its small footprint and USB-C PD compatibility make it one of the more travel-friendly high-power chargers currently available.

Does it support NiMH batteries?

Yes, up to 15S NiMH/NiCd packs are supported, which covers the vast majority of receiver and hobby-grade NiMH battery configurations.

Care Tips for Long-Term Reliability

• Avoid stacking heavy gear on top of the unit in a bag — the small size makes it easy to forget it is in there
• Keep the USB-C port clean since it doubles as both a power input and a firmware/data connection
• Let the unit cool between back-to-back high-power 300W sessions rather than running it continuously all day
• Check balance lead connectors periodically for wear, since these see frequent plugging and unplugging in field use

Conclusion

The SkyRC B6 Neo 2 manages a rare combination: genuinely high charge power and a form factor small enough to disappear into a backpack pocket. Whether you are charging at home off a DC supply or in the field off a power bank, it adapts without asking you to compromise much either way.
