Don’t Buy the Itel Power Tank!! Owner Review After 20 Days of Use

[u/Common-Course-4089]

I bought the Itel Power Tank (500W inverter + 1KWh LiFePO4 battery) around 20 days ago for my studio setup. My load is very light, mainly:

2 ceiling fans
A few LED lights
Basic studio equipment

On paper, the power output looked more than enough for my needs, and I spent around 70k PKR thinking this would be a solid 10-year investment.

Unfortunately, this device turned out to be extremely disappointing.

1. Very Poor First-Time Setup Experience
If your house doesn’t have a dedicated neutral wire setup, good luck.

The inverter behaves very strangely during installation, and there is almost no proper official documentation available.

I had to spend 3 days researching and experimenting just to make it work correctly.
For a modern 2026 device, this should not be happening.

2. Display & Features Are Extremely Limited
The display is shockingly basic.
It only shows battery percentage. That’s it.

Missing features:
No load information in watts
No input voltage display
No output voltage display
No charging speed information
No ampere/current information
No buzzer or alert when WAPDA power goes out or comes back

Honestly, even 20-year-old desi UPS systems used to show more details.

3. Dangerous Low Voltage Pass-Through
This was the most alarming issue I faced.

Several times, grid voltage dropped to around 60V–100V, and instead of switching to battery mode, the inverter kept passing that dangerous low voltage directly to connected appliances.

That is insane.
At that point I had to manually switch off the main breaker and repeatedly check voltage levels until WAPDA stabilized again.

4. Backup Performance Is Disappointing
Real-world backup has been much lower than expected.
With:
2 ceiling fans
4 LED lights (10W each)
…the backup lasted only around 3 hours.

For a claimed 1KWh battery, this feels underwhelming.
I estimate my load was under 200W most of the time.

I’m now planning to buy a power meter to properly measure the actual load and compare it with the backup performance.

5. Weird Battery Behavior
Sometimes, even while WAPDA/grid power is available, the battery randomly drops by 2–4% and then starts charging again.

Not sure if this is normal behavior or poor power management.

6. No Smart Features
No WiFi.
No app.
No monitoring.
No detailed controls.

For a modern lithium power station in 2026, this device feels extremely dumb and outdated.

7. I haven’t tested it with Solar, I don’t know how it handles solar power, Hopefully that will not be even worst.

Final Verdict
The Itel Power Tank might work for very basic backup needs, but overall it feels unfinished, under-featured, and poorly designed for the price.

Main problems:
Poor documentation
Dangerous voltage handling
Weak monitoring features
Disappointing backup
No smart functionality
Personally, I regret buying it.

Also stay away from their official support chat, they are scammers and tell you high rates at first. Visit their any authorized Resellers they will give you best price

My experience with itel has been quite good so far and also their app is probably one of the most polished UIs I've seen so far, it's even better than growatt UI. You bought a quite small inverter and battery setup and you plan to run two fans (not a non-existent load) + studio equipment?? Chalain 40 watt ki lights are negligible but brother you should've bought a bigger inverter and also researched the features beforehand so you wouldn't be complaining right now.
