The search for high-quality equipment for reconditioning batteries often leads car enthusiasts to a Ukrainian manufacturer Powerman. Model Pendant 720 has established itself as a reliable assistant for servicing lead-acid batteries with a capacity of up to 200 Ah. This device combines the functions of a pulse charger, a desulfating unit and a power supply with adjustable output voltage.
Many car and motorcycle owners are wondering where to buy an original product so as not to run into a fake or refurbished used product. In this article we will analyze current prices, technical nuances and places where you can safely make a purchase.
It is worth noting that Pendant 720 often confused with the simpler models of the 600 or 210 series. However, it is the “seven hundred and twentieth” model that offers advanced functionality for working with deeply discharged batteries. The differences lie in the operating algorithms and maximum output power.
Technical characteristics and capabilities of the model
Device Pendant 720 built on the basis of pulse circuitry, which ensures high efficiency and compact dimensions. Unlike transformer analogues, it heats up less and weighs less. The input voltage is standard 220 V, and the output current is adjustable over a wide range, which allows you to charge both small motorcycle batteries and powerful truck batteries.
The key feature is the presence of a desulfation mode. The operating algorithm of the device allows you to restore sulfated plates by applying reverse current pulses, which extends the life of old batteries. There is also a training mode (cyclic charge-discharge), which helps determine the actual battery capacity.
The user can manually set charging parameters or trust the automation. Reverse polarity and short circuit protection makes the process safe even for beginners. The device screen displays the current voltage, charge current and time elapsed since the start of the process.

- 🛡️ Built-in protection against overheating, short circuit and incorrect connection of terminals.
- 🔋 Possibility of use as a power supply with voltage regulation.
- 📉 Discharge function for conducting a control and training cycle.
Difference from model Pendant 715
Model 720 is distinguished by the presence of a more advanced desulfation algorithm and the ability to work with batteries of higher capacity (up to 200 Ah versus 120 Ah for younger models). The cooling system has also been improved.
Where to buy an original charger
Purchasing electrical equipment is always a risk of encountering unscrupulous sellers. To buy pendant 720 original production, you should contact authorized sales points or large chain stores of auto parts. Manufacturer's official website Powerman contains a list of dealers, which is the most reliable way to check.
Popular marketplaces also offer this model, but here it is important to carefully look at the seller’s rating and reviews. Often, refurbished units with a replaced case are sold under the guise of new devices. You can distinguish them by the build quality and the presence of a hologram on the back panel.
The price may vary depending on the region and intermediary markups. Too low a cost should alert you: a high-quality element base cannot be cheap. The average market price corresponds to the segment of professional equipment for garage use.
⚠️ Attention: When purchasing from your own, be sure to check the operation of the device under load. Connect the discharged battery and make sure that the charge current corresponds to the declared one, and the screen does not go dark during voltage surges.
Instructions for first launch and setup
Before you start using it, you must properly prepare the device. Pendant 720 does not require complex initial calibration, but following the sequence of actions guarantees correct operation of the electronics. First, connect the terminals to the battery, observing the polarity, and only then turn on the device to a 220 V network.
After switching on, the display will show the current voltage at the battery terminals. If the battery is deeply discharged (less than 4-5 Volts), the device may not start in automatic mode. In this case, it is necessary to switch to manual mode and forcefully increase the voltage to 10-12 Volts.
To configure charging parameters, use the navigation buttons on the front panel. The menu is intuitive. Select the battery type (WET, GEL or AGM), since for gel batteries it is critical not to exceed the threshold voltage, otherwise the electrolyte will boil.
☑️ Check before launch
Comparison with competitors and analogues
There are many chargers on the market, but Pendant 720 occupies a niche of affordable professional equipment. In comparison with Chinese analogues like Berkut or Airline, the Ukrainian product wins in maintainability and honesty of the declared characteristics. Chinese models often suffer from overstating their power ratings.
Compared to more expensive brands like CTEK, then the Pendant loses in the presence of complex Bluetooth functions and premium design, but wins in price by 3-4 times. For ordinary garage use, the functionality of the 720 model is more than enough.
An important aspect is the possibility of repair. Coulomb's circuitry is open, spare parts are available, while many modern "smart" chargers are disposable in case of controller failure.
| Parameter | Pendant 720 | Budget analogue | Premium segment |
|---|---|---|---|
| Max. current | up to 20 A | up to 10 A | up to 25 A |
| Desulfation | Yes (pulse) | Often not | Yes (smart) |
| Maintainability | High | Low | Average |
| Price | Average | Low | High |
If you plan to charge AGM batteries, make sure that the appropriate mode is selected in the device menu. Charging WET batteries with normal current may permanently damage the AGM structure.
Typical problems and methods for solving them
During operation, users may encounter certain difficulties. Most often, the device writes an error or does not see the battery. This may be due to oxidation of the contacts or too low voltage at the terminals, which the electronics perceives as a lack of battery.
Another common problem is voltage readings going off. If you notice that Pendant 720 shows a voltage that differs from the multimeter by more than 0.2-0.3 Volts, calibration may be required. To do this, you can adjust the voltmeter readings in the service menu (accessible via a button combination).
Cooling fan noise is normal at high charging currents. However, if the noise becomes unusual (crackling, humming), dust may have gotten into the bearing or the lubricant may have dried out. In this case, it is better to replace the fan to prevent overheating of the power switches.
⚠️ Attention: Do not attempt to open the device case if it is under warranty. Broken seals automatically void the manufacturer's warranty.
Rules for safe operation
Safety is a priority when working with electricity and acid. Pendant 720 equipped with protection, but the human factor has not been canceled. Always provide good ventilation in the area where the battery is being charged, as oxyhydrogen gas may be released during charging.
Do not cover the operating device with rags or blankets, even if it seems that it is not heating up enough. Switching power supplies require free air flow to cool radiators. Overheating shortens the life of capacitors.
When disconnecting, first remove the plug from the socket, and only then remove the terminals from the battery. This will prevent sparking and a possible explosion of electrolyte vapor. Following this simple sequence will protect the equipment and the owner.
Maintaining the polarity and connection/disconnection sequence is the key to a long life of both the charger and the battery itself.
Owner reviews and summary
Analyzing forums and communities of car enthusiasts, we can conclude that the model Pendant 720 is in stable demand. Users praise it for its “honest” charging current and the ability to revive old batteries that other chargers consider dead.
Among the disadvantages, the length of the wires is often mentioned (I would like more) and the sometimes noisy fan. However, in terms of cost and functionality, these shortcomings seem insignificant. The device pays for itself in 2-3 seasons of active use.
If you are looking for a universal device for the garage that will allow you not only to charge, but also to diagnose and service the battery, then purchasing this model will be a rational investment. The main thing is to choose a trusted seller.
Can lithium (Li-Ion) batteries be charged with Coulomb 720?
No, absolutely not. The device is intended for use with lead-acid batteries only. Charging lithium batteries requires a completely different algorithm (CC/CV) and voltage, otherwise a fire or explosion may occur.
What should I do if the device beeps and flashes?
A beeping sound and flashing usually indicate a connection error (reversal) or a short circuit. Check that the terminals are connected correctly (+ to +, - to -) and make sure they do not touch each other.
Do I need to remove the battery from the car to charge it?
It is advisable to remove it to avoid voltage surges in the on-board network, which can damage the car’s electronics. If removal is not possible, be sure to disconnect the negative terminal from the body before connecting the charger.
