Turn your vehicle into a generator – OUPES 800W Alternator Charger officially released.

Exclusive High-Efficiency Charging Solution for Mega & Guardian Series

As outdoor living and power freedom become the foundation of next-generation travel, electricity is no longer just a consumable — it is the confidence behind every adventure.

OUPES now introduces the brand-new 800W Alternator Charger, designed exclusively for the Mega Series and Guardian Series power stations, allowing your mobile energy to be independent from campsites and unaffected by solar weather — truly enabling drive, charge, and go.

Why Do You Need Vehicle Fast Charging?

Whether you're an RV traveler, camping enthusiast, long-distance driver, outdoor worker, or someone preparing for home emergency backup —

You know that when power runs low, the fridge stops cooling, lights go out, devices shut down — a perfect trip can collapse instantly.

With OUPES vehicle fast charging, simply starting your car means carrying a power-on-the-go station:

RV Camping → Charge while driving, stay powered even in long-term outdoor stays

Long-distance Road Trips → Power station stays full, laptops and cameras never run out of power

Urban Power Outages → No grid, no weather dependency — your car becomes your backup charger

Field Operations → Continually power high-demand tools, keeping work uninterrupted

This is not an accessory — it is a true mobile energy extension system.

800W Ultra-Fast Charging — Up to 8× Faster

Traditional cigarette-lighter chargers are only around 80–100W, while the OUPES Alternator Charger delivers up to 800W, maximizing efficiency.

*Calculation Method & Notes：

1. 800W Alternator Charger formula:
   Charging Time (hours) = Capacity (Wh) ÷ 800W × 85% (system efficiency).
   Based on an estimated 85% system efficiency. Actual efficiency typically ranges from 85% to 90%, so calculated values are for reference only.
   
2. Traditional Cigarette Lighter Charger formula:
   Charging Time (hours) = Capacity (Wh) ÷ 100W × 85% (typical efficiency).
   *A 100W output and 85% system efficiency are used for estimation, reflecting common real-world performance.*
3. Time Saved is the difference between the two charging methods, highlighting the dramatic reduction in waiting time.
4. Key Insight:
   The 800W Alternator Charger is 8–9× faster than a traditional cigarette lighter charger, turning impractical overnight or multi-day charging into a task that can be completed within a single drive.

Three-in-One Functionality — All-Scenario Coverage 

More than fast charging — it is a true emergency power tool:

Mode	Function
Charging Mode	Rapidly recharges power stations (supports 12V/24V vehicles)
Reverse Charging	Power station can recharge vehicle/RV battery or perform emergency jump-start
Battery Maintenance	Low-current maintenance mode extends vehicle battery lifespan

One device in your car — whether the power station is out of power or your car battery is low — it can save the day.

Compatible With RV Batteries — Stronger Endurance

Supports 12V/24V RV batteries and works efficiently with the alternator to keep your power station charged wherever you go:

No more searching for electricity — you always have electricity.

Includes a 5m vehicle connection cable, suitable for SUVs, pickups, and RVs.

FAQ

Can I use this Alternator Charger on hybrid or electric vehicles?

It can be used with hybrid vehicles equipped with an alternator and starter battery, but it is not compatible with fully electric vehicles.

How do I know whether my vehicle supports this charger?

As long as your starting battery is 12V or 24V (input voltage 11V–35V), you can use this product. RVs, vans, and trucks are generally compatible.

Will using this product damage the alternator or vehicle battery?

No. The charger does not continuously draw 800W; it adjusts output based on available alternator power to avoid overload while achieving up to 800W safely.

Will this increase fuel consumption?

The impact is minimal. It uses surplus electricity generated while driving (even when interior electronics are off), so fuel economy is barely affected.

How long does it take to fully charge Mega and Guardian power stations?

Mega 1 (1024Wh) — 1.5 hours
Mega 2 (2048Wh) — 2.8 hours
Mega 3 (3072Wh) — 4 hours
Mega 5 (5040Wh) — 7 hours
Guardian 6000 (4608Wh) — 6.5 hours

Is this product suitable for self-installation?

Users with technical knowledge may install it themselves, but professional installation is recommended. Avoid high-temperature, sharp, or friction areas when routing cables, and ensure secure mounting. Do not cover the device during operation as it may generate heat.

What protection functions does the charger include?

Reverse-polarity, over-current, short-circuit, over-voltage, and under-voltage protection.

Will the charger drain my vehicle battery? Do I need to turn it off after each use?

It will not drain the battery. You can set custom voltage thresholds in the Cleanergy app to prevent excessive discharge. The device also supports reverse charging, allowing your power station to recharge your vehicle battery in emergencies.
