I have a power station but its internal battery is a 48 V, so when I run 12 V things you lose some efficiency stepping it down to 12 V. I also have a 12 V battery and I'll just often run those device devices directly from the battery and I get much more run time per ah of battery.
Community Reviews
This 12V 280Ah LiFePO4 battery is being used as affordable house, RV, boat, camper, and off-grid storage, with Bluetooth monitoring and enough capacity for serious loads. It is praised for running 12V devices directly, pairing well with solar, and scaling into 24V or 48V banks for larger systems. Real-world reports include trolling motors, backup power, and even air conditioning, though runtime drops fast on heavy AC loads. It is not a starter battery, and charging or wiring often needs the right lithium charger, fuses, and connectors.
The battery can be a strong value for energy storage, with multiple reports describing unusually low pricing compared with typical LiFePO4 battery pricing.
The battery can integrate into solar and EcoFlow systems, including setups that charge from solar and feed EcoFlow Delta units via XT60i inputs.
The battery can run 12V devices directly without an inverter, which can improve efficiency versus stepping down from a higher-voltage power station.
The battery supports real off-grid and RV use cases, including running an air conditioner for about eight hours in a trailer setup.
The battery can work well for backup power with an inverter, including a reported longest outage of about fourteen hours while still leaving remaining battery juice.
Coupon and checkout reliability can be inconsistent, including reports that promo codes fail to apply or stop working during checkout.
The battery is not intended for vehicle cranking, and it lacks the CCA needed to start a car.
The battery can drain quickly with high-power AC loads, and a 13500 BTU unit running constantly was estimated to last under three hours.
The battery may require careful charging compatibility, since some setups report Bluetooth not working and the battery not registering full state of charge with an AC-to-DC controller.

Ya, pretty sure. I don't know where you read everything online, but it is well known in the camper community that lead batteries can be exposed to hot and cold temperature (and therefore installed say under a camper, where they get very cold in Winter, and very hot over black asphalt). LFP batteries not so much. But... whatever, just trying to help, not argue.
