BEAUDENS Portable Power Station 166Wh/52000mAh Lithium Iron Phosphate Battery Solar Generator, 2000 Cycles, 230V AC and 3 USB Ports, for Outdoors Camping Travel Fishing Emergency Power Supply Backup

At first I was unsure of the description MPPT solar controllers on their own are quite expensive. So I thought it may be a PWM. However it's not it's definitely an MPPT and that's fantastic. It means the optimal charge rate from a solar panel even when the sunlight reduces. The build quality seems excellent with an aluminium body, it would have been nice to have a USB C but the smart charging USB port goes a long way to over come this. The two negatives I'm not struck on were the import port for charging being right next to the output ports. It's clearly labelled but I bet someone will try to use the wrong port at some point as they are the same connector. For me this isn't a big issue but just occurred to me to mention. The only other negative is the screen and charge read out, it's ok but would have preferred a percentage charge readout rather than 5 blocks. Over all the unit is excellent and those negatives are that big for me to drop a star from the rating. I have used it to charge 6s lipo batteries via the DC out. It will happily fully charge 6 X 6s 1100mah, I charged 4A. You can't go above 4.3 amps charging 6s as the 12v DC out is looking limited to 10A and the charger needs to step the voltage up. However this was the hardest test I could think of to apply constant load and it did extremely well. The unit apparently will automatically cut off when the voltage drops too low to protect against over discharge. This must be below 10V as I set a 10V limit on the my charger and I hit that before the unit cut off. That does seem low for a lipo but I'm not familiar with LifePO4 batteries so I would assume it's fine. It's 2000 cycle life battery so I'm ok if it shortens the life by a few cycles. Finally, at the price it's way better than I was expecting and the MPPT controller in this price range is such a nice surprise. Non of the point about are enough to make me drop a start they are more be aware. So top product Beaudens!

This now sold as the Swarey Power Station, I have been using leisure batteries in a rolling trunk to power my Astro gear for ages, this thing is tiny by comparison but has roughly the same capacity as the bigger Celestron power tank. Also the case seems to very solid aluminium construction so quite sturdy, the carry strap is comfortable in the hand and if needed could easily be replaced with a long shoulder strap for convenience. As for capacity the first charge lasted about a week of roughly I hour a day use while solar imaging running an EQ5 Goto and cooled mono camera. I checked voltage regularly and it seemed to hold about 12.2V output with both devices running. Plugging in a laptop to the AC output drops this to 11.8v so not good for running the mount so it's a case of one or the other. It has also successfully run a night time session (3 hours) powering a heavyweight CEM 120 mount and mono camera and dropped about 1 bar in charge. At the end of the week charge had just dropped to 2 bars. We have also used it to power a small Coleman chiller box on a picnic this weekend, while out it dropped about 1 bar for an hour, we tried leaving it to run in the car but it got hot and shutdown safely so overall a good test. In truth it does not have the capacity of my old monster power tank with 85Ah SLA battery but that unit suffered badly in the cold and needed a new battery every 18-24 months so I'm hoping this a longer lived. Also 2kg Vs 25kg and compact size make it a winner. If I have a regret, it's not buying one sooner. Jan2022 Update I have tried running the mount with this over winter, it worked but seems to be sensitive to cold, it ran the CEM120 for about 3 hours in just above freezing conditions then shutdown still with 90% charge, it seems that it will need a box or bag to keep warm on cold nights. Still highly impressed with it. March 2022 Update. The earlier issues got worse and "up time" went down to a few minutes, after a some, at time frustrating messages with Swarey Support to describe and diagnose the problem including trying to provide a video of the unit a refund has been issued. Disappointing but ultimately OK as a result. Will I replace this unit with the rebranded Swarey unit, possibly not, much as I loved this little unit, with 20/20 hindsight the larger unit may have been better, but I will certainly look at the bigger Swarey unit.

I saw this product reviewed on YouTube by camper van enthusiast, I though it was great, so much so that I have bought one. This is a must have if like me you have a Day Van, Camper etc. Connectivity & battery life is great, have mine connected to the solar panel on the roof, just remember, this will not charge your washing machine, but is fabulous for phones, laptops & small electrical appliances. Also we recently had a power cut and this little unit ran a Microsoft surface pro, iPad along with changing a phone with no effort at all. Definitely recommend & wouldn’t be without it.
