ALLPOWERS S2000 - Solar Generator
I was sent the AllPowers S2000 for review so I didn’t pay for this product. All opinions here are my own and nothing has been scripted or reviewed by AllPowers.
I made this video back at the start of 2023 but I’m not writing this part of the review until June 2023 so I’ve been using the battery for an extra 5 months and am even more familiar with the good and the bad than I was then.
If you’re after a look at the product and want to know full details of the specs, take a look at the video.
Let’s start with my conclusion so you don’t need to read more than you have to and then I’ll list the good and the bad point of the product.
Would I Recommend the S2000
If money is tight and you are after the highest number of Wh/£, these are great value. They have their quirks and are not as refined as some of the competition but the AC inverter is reliable and the DC outputs do what they say.
It charges and it delivers power. If you need something a bit more refined with more app features and functionality, you’ll need to spend a little more and go with something like an EcoFlow or Bluetti.
The Good
Excellent capacity for the cost (1500Wh)
A good number of outputs covering most requirements including 2 x 100W PD 👍🏻
Reliable 2000W (4000W surge) inverter which is often noise free at low power (under 200W).
Solid carrying handles.
XT60 solar connector gives good reliability and compatibility.
All the ports (except AC input) are on the front making access simple when used in an environment with limited space.
No power brick is required. AC charging is through a C13 ‘kettle’ lead.
App requests but does not need a login at the time of writing.
Solar and AC input can be combined to allow up to 900W input.
Comes with a made-to-measure waterproof case.
The unit has a solid feel overall and has a nice robust, industrial design which I like.
The S2000 has a flat useful space on top that can act as a table or even a stool if you’re not too heavy. I found this surprisingly handy!
The Bad
AC input is limited to 400W so no option for fast charging.
UK mains outputs are not safety compliant and do not have shutters on the live and neutral pins. They feel flimsy to use and don’t have the usual firm contact of a UK socket. AllPowers have chosen to cut cost here and use the same AC outputs for multiple regions which means you get the lowest common denominator as far as safety goes.
Fan is fairly quiet but has a smattering of high-frequency tones with it which is extremely irritating. There’s an audio sample below.
Calibration is poor so it’s hard to judge how much power you actually have remaining (a common problem on large batteries like this). The battery will fail at 30% but charge at full power at 100% for over an hour.
Only one power reading is visible on the unit display with output power taking priority (both can be viewed through the app)
After the voltage from a solar panel drops (dusk), the unit begins to constantly spin up a fan, click and repeat until you unplug the solar panel. It’s very irritating as I am a user who likes to be able to leave a panel connected.
No DC 5521 outputs. I personally use these all the time but it might not matter to many.
The app has an amateur, unfinished feel to it and adds little value except being able to see input and output power at the same time.
USB ports are poorly marked. Apparently, some are fast charge but I can’t manage to get more than 5V out of any of them so 🤷🏻♂️
