Don't buy Mini UPS WGP UPS103C 20000mAh: Why I threw away 2800 UAH
Today, the market is flooded with offers of uninterruptible power supplies (UPS) for routers. Everyone is trying to sell you «more capacity» for a lot of money. I also fell for this and bought a model that many consider to be the benchmark — Mini UPS WGP UPS103C for 20000mAh (model 42-00253).
Paid for it 2800 UAH, hoping for 12 hours of battery life. Now that device is sitting on the shelf, I want to warn you against this expensive mistake.
The main trap: There is capacity, but no charge
The case proudly says 20,000 mAh. Inside are 4 batteries of 5Ah each. That sounds solid. But there is one critical problem that sellers are silent about: charging speed.
In our realities, when light is provided on a schedule (for example, 2 hours on, 4 hours off), this device turns out to be completely useless. And here's why.
The secret of the “bottleneck”: Connectors and power supplies
Pay attention to the design of outdated WGP models. They charge via a separate external power supply (a kind of "brick"), which plugs into a separate DC 5.5×2.1 mm connector on the side.
Why is this a technological impasse?
Weak charging: This connector is not physically designed for high currents. The manufacturer did not bother with the development of a new board, so there is a current limit inside (often only 0.5 - 1 Ampere).
The mathematics of disappointment: To charge such a huge 20,000 mAh «bank» with a current of 1 Ampere, you need about 20 hours of continuous light!
The straw effect: When the light comes on for an hour or two, this WGP only manages to "swallow" 5-10% of energy. You use a tiny fraction of what you paid for, and the batteries are never full.
Modern alternative: 220V directly into the housing
Look at new, modern developments (for example, from Hoco or Axus brands). They do not have an external power supply — the 220V cord plugs directly into the UPS housing.
This is the main quality marker:
This means that inside is powerful intelligent charging, like on your iPhone or Samsung.
Such devices are able to charge quickly. They “understand” that the light was given for a short time, and are able to gain 70% charges in just 50 minutes.
While the old WGP is just «waking up,» the modern UPS is already ready for the next blackout.
Why is the WGP UPS an outdated solution?
Brand WGP continues to ride on its old reputation, but today their products are a monument to outdated technologies. The main problem with the entire line is that from the compact WGP 8800 mAh to the top WGP 25000 mAh — is that the charging time is not optimized by the processor at all.
The manufacturer uses strict current limits, which turns the energy recovery process into infinity.
WGP UPS line suffering from critically slow charging:
WGP 8800 / 10400 mAh: Even these low-power models work on the old charging logic.
WGP 15600 mAh: A popular model, but an absolute outsider in terms of energy recovery speed.
WGP 25000 mAh (12V/19V/24V): A real "braked giant", a full charge of which takes from 12 to 24 hours.
My advice: Instead of one clumsy UPS for 2800–3500 UAH, it is much more efficient to take 2 or 3 modern devices with real technology Fast Charge. And how to combine them into one super-powerful system through Schottky diodes, so that they work in turn and charge in parallel — read in my next article.
Don't buy the numbers on the box. Buy technology that can charge in those short hours when there is light!
Simple test before buying: check the WGP UPS for charging speed
If you still have doubts, do a simple experiment right in the store:
Choose any WGP UPS (regardless of the declared capacity).
Ask the seller place the device on charge exactly on 1 hour.
Look at the indicator: How many divisions were added during this time?
You will see with your own eyes: these 20,000 or 25,000 mAh «monsters» will not have time to add even one full division in an hour. This is the real speed at which you will live during blackouts.
Then you will immediately understand: do you need beautiful numbers on the case or stable Internet at home?
What solution will be the most optimal?
After analyzing dozens of models, we at Electro Shop settled on an option that is perfectly balanced in price, reliability, and, most importantly, the speed of energy recovery.
I recommend the line proven by our tests UPS for AXON router.
Why is AXON a technological breakthrough?
Unlike legacy schemes, in uninterruptible power supplies AXON used new generation control board with intelligent charging algorithm:
Fast Charge Mode: In the first stage, the board supplies high current, allowing the main battery capacity to be charged incredibly quickly (ideal for «2 through 2» schedules).
Intelligent charging: When the battery is almost full, the current gradually decreases. This ensures safe «top-up» of capacity, which significantly extends the life of Tesla Industrial batteries.
Efficiency: You get maximum energy in the minimum time spent in the socket.
My choice — AXON 10500 mAh (DC1018L)
This is the "golden mean" for home internet. It is designed to be able to fully charge in short intervals between shutdowns.
Professional assembly: 4 original Li-ion 18650 cells are used Tesla Industrial.
Warranty and testing: Each device undergoes my individual inspection before shipment.
👉 Order AXON 10500 mAh (DC1018L) — charging in 1 hour!
