Gaiaray Power Station (LiFePO4, 153.6 Wh)
TL;DR
- Gaiaray 200W Power Station from AliExpress uses a LiFePO4 pack rated at 153.6 Wh and offers AC, USB-A, USB-C, DC5521, and torch outputs.
- Inside, the charger is a 15V, 30W unit with a 2A current limit, and the USB rails use CX8824 and IP6520 adapter boards.
- The station weighs 1,777 g, measures 180 x 130 x 185.5 mm, and the included charger fills it in just under 6 hours.
- Capacity is fine, but the AC socket is loose, cooling is weak, the fan gets loud under load, and the DC outputs are only partially stabilized.
- The charging input has no current limit, so it is not suitable for solar panels, and the battery pack has no temperature sensor.

Gaiaray 200W Power Station from AliExpress.
Price: ~160 zł
Weight: 1,777 g
Dimensions: 180 x 130 x 185.5 mm
Batteries: LiFePO4, 153.6 Wh
Torch: 2 brightness levels + flashing mode
USB-A output: 5V 2.4A
USB-C output: 5V/9V/12V 20W
2 DC5521 outputs: 12V 3A
AC output: 220V 200W
I bought it out of curiosity to see if you could get something useful for 160 zł.
Power Station:
Charger (15V, 30W):
This is a charger, not a power supply. 15V with a current limit of 2A. Red/green LED indicating charging status.
Interior:
USB-A power adaptor (CX8824: 5V 2.4A):
USB-C power adapter (IP6520: 5V/9V/12V 20W):
AC output:
No load:
150W load (halogen, meter read 234V):
Capacitance test:
12V output, 3A load:
12V output, 0.5A load (continuation following completion of the 3A test):
After testing:
The casing looks fine; I’d say the display is a bit too fast, but it’s only 160 zł, so I won’t quibble.
The indicator light has two brightness levels plus a flashing mode – that’s fine.
The DC outputs have a combined limit of around 4A. USB-A: 5V 12W. USB-C: 5V/9V/12V 20W. At the 12V outputs, the voltage from the battery is 11V...14.5V; it isn’t stabilised.
AC output: the socket is too loose; some plugs can lose contact if the cable is moved. The ventilation holes are poorly positioned, so the cooling isn’t very effective. I carried out a longer test with a 20W load and the fan ran quite loudly. I didn’t test it for long at 150W.
Charging input: no current limit; not suitable for a solar panel. Connect only a charger! The included charger charges the station in just under 6 hours.
The station switches off once the battery has discharged to ~10.75V.
A cell balancer is connected to the cells. However, there is no temperature sensor.
Capacity is fine.
For 160 zł, it’s not a bad little toy for an electronics enthusiast. There’s a bit of spare space in the casing, so you could fit something of your own in there..
It’s a shame that the 220V inverter is integrated with the battery and the balancer, as I’d have swapped it for something else (with an adjustable DC output).

The capacity is a bit on the small side, but at this price it seems fine. Generally speaking, you can fit the unit with higher-capacity cells, along with a BMS, and then it’s actually quite a decent charger.... [Read more]
I think that if we removed the AC converter, we could probably fit in just as many cells again. [Read more]
Er, wouldn’t it be better to remove the casing? Then how many could you fit in? :D [Read more]
