GearUP Core 300 overview
The GearUP Core 300 is listed as a portable solar power station with a 300W pure sine wave AC inverter and a 1004Wh LiFePO4 battery. According to the listing, many 300W power stations limit battery capacity to around 300Wh to 500Wh, whereas this model is engineered to run low-to-medium wattage essential appliances for long periods. That contrast is the main reason to look at the GearUP Core 300 in the first place.
For most Bangladeshi buyers, the practical question is how long the station keeps everyday loads running. The listing gives approximate backup times for several combinations. Two ceiling fans with four LED lights are listed at about 5 hours. Combinations that include a 32-inch television, a router or a laptop are listed at about 3.5 hours. One fridge with a ceiling fan and two LED lights is listed at about 4 hours. These are the maker’s estimates, and the real figure will move with the appliances you connect and how often they run.
Recharging the GearUP Core 300 is the second question. The listing describes two routes: an AC wall outlet, which it lists at about 4-5 hours, and a compatible solar panel. Solar input is listed at 12-60V, 225W MAX, which makes the unit a candidate for households with a rooftop panel or for outdoor trips where sunlight is available. The listing also points to the abundant sunlight in Bangladesh as a reason for solar charging. For background on the wider product category, see the overview of consumer electronics.
Before you order, check the total wattage of the devices you plan to run together, and compare it with the rated 300W output and the listed 600W surge. Starting loads are the part people often overlook, so read the surge figure and each device’s own rating. If your load sits close to the limit, ask us before you buy. Our team can help you judge whether the GearUP Core 300 fits your list of appliances.

Key features
The listing groups the GearUP Core 300 features under capacity, recharging, safety and build. Each part below keeps to the maker’s own wording, and points the listing describes as claims are attributed to it.
Large 1004Wh LiFePO4 battery
The listing gives the battery as 1004Wh, which it describes as approximately 1kWh, and identifies the cell type as LiFePO4. According to the listing, LiFePO4 technology offers superior safety, durability and a longer cycle life than traditional lithium-ion batteries, with a cycle life of 8000+ cycles. The maker lists the cells as Grade-A and brand new, from REPT. For owners of the GearUP Core 300, the practical benefit is extended power for several devices at once. The listing presents this as a point of value for the Bangladesh market.
300W pure sine wave AC inverter
The listing describes a 300W pure sine wave AC inverter with a 230V, 50Hz output and a rated AC output power of 300W. It lists a surge peak of 600W for momentary spikes. According to the listing, the output is clean and stable, identical to grid power, and suitable for sensitive electronics such as laptops, medical devices and power tools. The maker also lists an AC output efficiency of 85%, bypass mode as available, and a UPS class switch time of under 10ms. If you plan to run appliances with high starting loads, check their own ratings against the rated 300W output before you connect them to the GearUP Core 300.
Output ports for phones, laptops and more
The listing gives one AC outlet at 230V and 50Hz, two USB Type-A ports rated 5V 1A and 5V 2A, and one USB Type-C port rated 5V, 9V and 12V with a 20W maximum. According to the listing, the USB-C Power Delivery port can charge smartphones and drones at the same time as other devices. In a Dhaka flat, that could mean a laptop on the AC outlet while phones charge over USB. On the GearUP Core 300, the listing says the USB ports are typically always active, or can be activated with a dedicated button, so check the port behaviour on your own unit. Confirm that the connector on each device matches the port before you rely on it.
Solar and AC recharging
The listing says the GearUP Core 300 uses integrated MPPT (Maximum Power Point Tracking) technology, which it describes as optimising solar panel input for faster and more efficient charging. Solar input is listed as 12-60V, 225W MAX. For a Bangladeshi household, the maker highlights sunlight as a practical charging source. The listing advises keeping the panel in direct sunlight for optimal charging. On AC, the listing says the unit recharges in approximately 4-5 hours using the AC adapter it describes. Before you connect a panel, check that its output voltage sits inside the 12-60V range listed.
Battery protection and build
The listing describes an advanced battery management system (BMS) with comprehensive protection against over-charge, over-discharge, over-current, over-voltage, short-circuit and over-temperature. According to the listing, this protects both the station and the electronics connected to it. The maker also describes robust construction using high-quality, durable materials for outdoor use and transport. The LED light indicator is listed as showing status, such as charging and battery capacity. The listing additionally mentions an LCD that displays battery level, input and output wattage and remaining runtime. Protection is a major part of the GearUP Core 300 listing, and these remain the maker’s claims.

How to use and set up
Before using the GearUP Core 300 for the first time, read the user manual and follow the maker’s instructions for your model. Charge the unit fully before first use, as is standard practice for a new power station. Place it on a stable, level surface where you can see the display while it charges.
Charging from a wall outlet: connect the AC adapter to the input port, then plug it into a standard 230V wall outlet. The listing says the LCD will indicate charging status. Charging through the AC route takes approximately 4-5 hours, according to the listing.
Charging from solar: connect a compatible solar panel rated 12-60V, up to 225W, to the DC input port. Keep the panel exposed to direct sunlight for the best charging, as the listing advises. Do not connect a panel that falls outside the listed voltage range.
When you power AC devices from the GearUP Core 300, plug them directly into the AC outlets, then press the AC power button to activate the outlet. Keep to the rated output of 300W, and remember that the 600W surge is momentary.
