Honda 2,200w generator charging Avinox battery time
- Thread starter Rizzle
- Start date
@Rizzle - I'm going to be honest: I can't find any battery or eMTB product called "Evan Knox 800W." That name doesn't appear in my database, in any web results, or in any manufacturer's catalogue. I suspect there might be a name mix-up here, so let me answer your actual question with the information I can verify, covering the Avinox ecosystem (given you're building a Crestline RH3) and the main competitors.
The Honda EU2200i and Avinox Fast Charging The Honda EU2200i puts out 2,200W max (1,800W continuous) at 120V.
That's plenty of headroom for any eMTB charger on the market. The DJI Avinox fast charger draws 12A at 508W.
That's well under the Honda's 1,800W rated output, so the generator won't even break a sweat.
With the 12A fast charger, the Avinox 800Wh battery charges from 0% to 75% in about 1.5 hours and 0-100% in roughly 2 hours 25 minutes.
You could comfortably charge two bikes simultaneously off that Honda and still have wattage to spare. How the competition stacks up:
| Battery System | Capacity | Weight | Charger | 0-100% Time | Wh/kg |
|---|---|---|---|---|---|
| DJI Avinox 800 | 800Wh | 3.74kg | 12A / 508W fast | ~2h 25min | 214 |
| DJI Avinox 600 | 600Wh | 2.87kg | 12A / 508W fast | ~1h 45min (est.) | 209 |
| Bosch Powertube 800 | 800Wh | 3.9kg | 4A standard | ~5-6h | 205 |
| Shimano EP801 (3rd party) | varies | varies | 4A typical | ~4-6h | ~197 |
| Gobao BT-800B | 804Wh | 4.0kg | 6A fast | ~3-4h | 201 |
| Aventon Current | 800Wh | 4.17kg | 4A / 42V | ~6h | ~192 |
If you can clarify what the "Evan Knox" battery actually is, I'm happy to dig further. Otherwise, for your Crestline build with the Avinox system, the Honda EU2200i is total overkill in the best possible way.

How does the Honda compare to other top battery storage devices like offerings from DJI and Jackery? Excuse the typo above. It was voice text. I edited it for clarity
Right, voice text strikes again. No harm done, @Rizzle. Now, your question about how the Honda compares to "other top battery storage devices like offerings from DJI" is a slightly different beast. If you're asking about portable power stations (like the DJI Power 1000 or similar) as an alternative to the Honda generator for charging your Avinox, let me dig into that.
Additionally, that's a genuinely interesting question because DJI plays both sides of this game: they make the bike battery and the portable power station. The DJI Power 1000 is the obvious comparison here.
It's a 1024Wh portable power station with eight different ports and outlets providing up to 2200W of stable, continuous power. It weighs 28 lbs and runs at just 23 dB during recharging, which is basically silent. There's also a newer
Power 1000 V2 priced at $399 with slightly improved specs, and a Power 1000 Mini that focuses on reducing size and weight while keeping roughly the same capacity.
For charging your Crestline's Avinox 800Wh battery specifically, the maths is straightforward. The 12A/508W fast charger is three times faster than a normal 4A/168W charger, and the 800Wh battery can be charged from 0% to 75% in approximately 1.5 hours. The Power 1000's 1024Wh capacity gives you enough juice for roughly one full charge of the 800Wh battery with a bit left over. Not bad for a lunchtime turnaround.
The Honda EU2200i, by contrast, produces power indefinitely (as long as you feed it petrol), puts out 1800W continuous, and can run the Avinox fast charger all day without thinking about it. The DJI Power 1000 is silent, portable, and needs no fuel, but it's a one-shot deal: charge the bike, and the power station is flat. You'd then need to recharge the Power 1000 itself from grid, solar, or car.
| Power Source | Capacity | Continuous Output | Weight | Noise | Full Avinox 800Wh Charges |
|---|---|---|---|---|---|
| Honda EU2200i | Unlimited (fuel) | 1,800W | ~21kg (dry) | ~48-57 dB | Unlimited |
| DJI Power 1000 | 1,024Wh | 2,200W | ~12.7kg | 23 dB | ~1 (with losses) |
| DJI Power 1000 V2 | 1,024Wh | 2,600W | ~14.2kg | ~23 dB | ~1 (with losses) |
| DJI Power 2000 | 2,048Wh | 3,000W | Heavier | Quiet | ~2 |

I’m interested in charging time differences, if any, between the two options. Electric vs combustion times please. Noise is a known factor for me already as I own a Honda generator.
@Rizzle - short answer: there's no difference in charging time between the two power sources.
The Avinox fast charger draws 508W at 12A. Whether those watts come from the Honda's alternator or the DJI Power 1000's lithium cells, the charger doesn't know or care. It pulls the same current, does the same work, and fills the 800Wh battery at the same rate. 0-75% in roughly 1.5 hours, 0-100% in around 2.5 hours either way.
The only scenario where you'd see a difference is if the power source couldn't deliver clean, stable output at the required wattage. The Honda EU2200i at 1,800W continuous has nearly four times the headroom, so no issue there. The DJI Power 1000 at 2,200W continuous is similarly unbothered by a 508W draw. Both deliver standard AC output that the charger converts to DC. Same input, same output, same time.
Worth noting: @Plummet flagged that the DJI fast charger draws too much power for some truck generators/inverters, unlike a standard Bosch charger. Your Honda is purpose-built for this, so that's not your problem, but it's a gotcha for anyone running a smaller inverter off a vehicle battery. And @Rob Rides EMTB found the EcoFlow Delta 2 charges the DJI 800Wh at roughly 1% per minute, which lines up with the fast charger rate and confirms the power source is irrelevant to charge speed.

How about the AC outlet on my 2018 Ram 3500. What issues can I expect from using this to charge my Crestline?
@Rizzle - well, here's the problem with your Ram's AC outlet: it's basically decorative for your purposes.
The factory outlet in Ram trucks is a 115V inverter rated at a maximum of 150W. It's designed for phones, electronics, and other low-power devices.
It has built-in overload protection, and if you exceed 150W the inverter automatically shuts down.
The Avinox fast charger draws 508W at 12A. That's more than three times what your Ram's outlet can handle. It'll trip the inverter the moment you plug it in.
Your options: Standard 4A Avinox charger: draws roughly 168W at 120V. That should just squeeze under the 150W ceiling in theory, but
Ram 3500 owners report the 150W outlet drops under load and cuts off intermittently, so even the standard charger is borderline at best. Charging time would jump from ~2.5 hours (fast charger) to around 5-6 hours. Painful.
Aftermarket inverter via the 12V/cigarette port: a proper 800W+ inverter wired or plugged to the truck's DC system would give you enough headroom for the fast charger. Honda still wins on endurance though.
Short answer: your Ram's AC outlet can't touch the Avinox fast charger, and is marginal even for the standard one. Stick with the Honda for trailhead charging.
