MARSTEK M1200 Portable Power Station

The Philippine SRP flyer sells this unit as the "M1800 Portable Power Station" (named for its 1,800 W AC output). The flyer's specs (1,800 W AC output / 3,600 W surge, 1,030 Wh LFP, 1,200 W AC input, 800 W PV input, expandable up to 2,060 Wh) match the M1200 engineering documents. Use "M1800" with customers if that is the local retail name, but match it to the M1200 datasheet and manual. No source in Drive explicitly says the two names are the same product, so confirm the model on the box.
What it is: a 1,030 Wh LiFePO4 portable power station with two AC outlets (1,800 W rated, 3,600 W peak), USB-C (100 W + 45 W), 2 × USB-A, a 12 V car-charger socket and a DC5525 port. It charges from the wall (about 1.3 h), from solar via XT60 (800 W max, 12–59 V), or from a car (120 W). An optional P1200-M extra battery doubles capacity to 2,060 Wh.
Who it's for: households that need portable brownout power for bigger appliances than a powerbank can run (electric fan, TV, laptop, router, even short bursts of a 1,000 W appliance), plus camping, events and mobile work.
Best for
- Brownout backup for fans, lights, router, TV, laptop and phones, with no installation needed.
- Running short high-power loads up to 1,800 W (e.g. a 1,000 W electric drill or oven for under an hour).
- Solar charging with any brand of panel within 12–59 V DC and up to 800 W.
- Outdoor work, events and camping. Note: not allowed on aircraft (over 100 Wh, per the manual).
Key features
From the M1200 datasheet and manual:
- 2 × AC outlets, 1,800 W rated / 3,600 W peak, with a resettable overload-protection switch. Over-power shuts off AC output; press the button to reactivate after removing the load.
- USB-C1 100 W, USB-C2 45 W, 2 × USB-A 18 W each, car charger / DC output 12 V / 10 A (120 W, shared).
- Three charging options: AC (about 1.3 h), solar via XT60 (800 W panel, 1.5–5 h), car charger (9–12 h). Times are manual estimates and depend on conditions.
- MPPT solar charge controller; BMS with OVP, UVP, OCP, SCP, OTP and UTP.
- Expansion: extra-battery port for the P1200-M (1,030 Wh, sold separately), up to 2,060 Wh total (e-Catalog, SRP flyer).
- TFT display + MARSTEK app over Bluetooth (4.2) or Wi-Fi. The app can set a no-load / light-load auto-shutdown timer for AC output.
- Display icons: expansion pack, overcharge alarm, Bluetooth, Wi-Fi, timing function, AC charge power, solar charge power, AC output power, DC output power, battery level.
Example run-times (manual's illustrative estimates)
| Device | Estimate |
|---|---|
| LED light 12 V / 5 W | 175 h |
| Fan 45 W | 19 h |
| TV 110 W | 7.5 h |
| Car refrigerator 65 W (car-charger outlet) | 13 h |
| Hair dryer 800 W | 1.1 h |
| Laptop (60 Wh) | 14.5 charges |
| iPhone 15 (3,349 mAh) | 66 charges |
Real run-time depends on the appliance, temperature and battery condition.

| Item | Datasheet | Manual | Other |
|---|---|---|---|
| AC input | 1,000 W max. | 1,200 W max. | SRP flyer: 1,200 W AC input |
| Dimensions | 400 × 195 × 200 mm | 462.7 × 195 × 247.8 mm | e-Catalog: about 40 × 19.5 × 20 cm |

The manual dimensions are likely measured including the handles, but no source says so. Confirm AC charging power on the unit label. All documents specify 50 Hz AC output. The Philippine grid is 60 Hz, and no source confirms a 60 Hz setting, so check with Silvera Solar Power before promising 60 Hz output.
Price (SRP)

Per the SRP flyer in Drive, the "M1800" Portable Power Station is ₱60,000 (original ₱68,000). The P1200-M extra battery is not priced on the flyer. Confirm current pricing with Silvera Solar Power before quoting. See the price list.
Installation & safety
No installation is needed. Follow the manual's safety rules:
Do not use the product beyond its output rating (1,800 W AC). Overloading may cause fire or injury; the over-power protection will shut off the AC output.
- Charge before first use with the power cord. Charging temperature 0–40 °C; output use -10–40 °C. Below freezing, keep the unit in an insulated, temperature-controlled place while charging.
- Storage: if unused for a long time, recharge every 3 months, keep the battery at 60–80%, and store it cool and dry. Do not leave it in direct sun (e.g. in a car or truck bed).
- Do not: disassemble, put fingers into the product, immerse it in water, stand on it, use it near strong static or magnetic fields, or expose it to flammable gas or to temperatures above 130 °C.
- Supervise when used near children. Use only manufacturer-recommended attachments; pull the plug, not the cord.
- Air travel: not allowed on aircraft (lithium batteries over 100 Wh).
- Press the AC power button to switch AC off when not in use, to save power.
- Warranty: the manual states 5 years from date of purchase (proof of purchase needed). Confirm the local warranty policy with Silvera Solar Power.
