Description

Description

The Andowl Q-DP9921 car battery charger is an automatic charger controlled by a microprocessor, offering intelligent and automatic adjustment of the charging current and battery maintenance capability. With this technology, the charger automatically selects the appropriate charging parameters for each battery, ensuring safe and effective charging.

Automatic voltage detection is another smart feature of the charger. It is used for the automatic recognition of the battery type. This ensures that the charger will adjust the charging according to the battery's requirements, eliminating the need for manual adjustments.

Additionally, the charger features a charging operation button that can be activated with a simple touch. This facilitates the activation of the charger, offering an easy and quick operation without unnecessary complicated steps.


Multiple Compatibility

The Andowl charger is suitable for 12V batteries, compatible with SLA, WET, MF, FLOODED, GEL, VRLA, AGM, EFB batteries and can be used for batteries in cars, motorcycles, boats, lawnmowers, and more.

Automatic Protection

The Andowl battery charger offers safety features such as reverse polarity protection, overcurrent protection, overload protection, overvoltage protection, overcharge protection, and over-temperature protection.

Simple and practical use

Using a backlit LCD screen, the Andowl battery charger clearly and visibly displays the charging status and battery condition on the LCD screen.

What does it mean that the Andowl Q-DP9921 is a battery charger?

The battery charger is used to charge the car battery, so it remains in good condition and provides the necessary power for the electrical systems and the engine to operate. This is important, especially if the car is not used for long periods of time.

Therefore, it cannot be used as a jump starter as it has only a charging function.

Repair Function

The pulse repair function can help you fix your battery loss and extend its lifespan. 

Note: It cannot activate a depleted battery or repair a severely damaged battery. Also, it cannot repair a battery to 100%.

  • Mine has the red color. No problem, it works perfectly! Especially with new technology AGM batteries, where the charging systems of cars before 2019 barely charge them to 12.6V, with the charger in less than 4 hours it reaches 12.9-13.0V. Absolutely satisfied with the purchase at €13 plus shipping.

    Note: the red version is also up to 6A. It can restore the battery if the charge has dropped. However, if more than 5 years have passed since the battery was manufactured, it won't work miracles.
    The repair function will 'send' current in pulses to break any salts inside, gaining a bit of capacity. On a 5-year-old YUASA, it gave a little more life and the repair process lasted about 3 hours in this case. The battery had been left uncharged for about 3 months and at temperatures of ~15-20 degrees. Cold plays a huge role, so in winter make sure to maintain your batteries. Remove the device FIRST from the power and then from the battery. With the crocodile clips on the battery, we can monitor its voltage and how quickly it drops to understand if our battery has a serious issue, such as not holding a charge for long.
    The only negative is the short cable and the hard-to-read indicators (in red) in a dark room. You can't see which mode you've set. But for €13, it is an essential accessory.

    Quite satisfied with the battery, 1.4 liter car, it was 2 years old and due to inactivity it dropped to zero. With 4 hours of charging it went to 40% and started. Then I charged it for another 8 hours and it went to 80%. Value for money.

    I have been using it for 8 months now to maintain my car's battery, which is also start-stop. Easy to use, with a small screen that shows plenty of information such as charging percentage, temperature, etc. My battery is 6 years old (the factory one) and after charging it you can feel the difference (it starts more powerfully and fires up immediately), so it really does charge it. Excellent for its price! It is not suitable for lithium batteries if you have one.

    For the price, it's quite good; it has indications for what you want to charge, e.g., a motorcycle, car, etc., and it automatically recognizes the voltage and type of battery. The two stars are deducted because the wires from the contacts are very short, making it difficult for the charger to sit in a position that is convenient for you to close the hood after connecting it or to close the seat on the motorcycle so that you don't leave it open to gather dust.

    Good charger. With the repair function, you can "boil" the battery that with another charger just showed 100% and did nothing. But with the wrong connection, it burned out immediately. The capacitor blew. It doesn't seem to have any type of fuse like a bulb

    Today I received it... I hope it is a good charger, obviously I didn't buy it expecting miracles, after all what miracle can someone expect from a device that costs €16 sixteen euros???... I bought it for maintenance on a start stop system FORD FIESTA ECOBOOST MK6... I will return for a full review after I confirm if it works, what performance it has and if in general it is worth buying regardless of its price!...3/8/2025...yes, it is worth buying, it is very good!

    The charger does not have any setting for the maximum desired charging current, which should normally be limited to 1/10 of the capacity in Ah. In my case, it charged a 6Ah battery with a current of 3A instead of 0.6A as it should have. This causes overheating (>45 degrees Celsius), and if left unattended, the battery will "boil" or even explode.

  • Quite satisfied with the battery, 1.4 liter car, it was 2 years old and due to inactivity it dropped to zero. With 4 hours of charging it went to 40% and started. Then I charged it for another 8 hours and it went to 80%. Value for money.

  • I have been using it for 8 months now to maintain my car's battery, which is also start-stop. Easy to use, with a small screen that shows plenty of information such as charging percentage, temperature, etc. My battery is 6 years old (the factory one) and after charging it you can feel the difference (it starts more powerfully and fires up immediately), so it really does charge it. Excellent for its price! It is not suitable for lithium batteries if you have one.
