Frequently Asked Questions

Panther is proudly Philippine-made, and has been a trusted manufacturer in the Philippine industry for over four decades. Our humble beginnings started in Karuhatan, Valenzuela in the 1970s; but we have since moved to Meycauayan, Bulacan. You can contact us here

Panther products can be purchased nationwide from our brick-and-mortar store dealers, as well as via online retailers on Shopee and Lazada

Just bring the Panther item to one of our authorized centers: (a) the original store you purchased the item from, (b) Panther’s authorized receiving center, or (c) Panther’s factory at Meycauayan, Bulacan.

Once handed over, let the staff know what issues you’ve encountered, and we’ll take it from there! For a more detailed account, check our “How to” guide

All Panther products are covered by the Panther Lifetime Service Warranty.

What this means: the service cost of diagnosing product issues and repairing the product will ALWAYS be free of charge – regardless of how long it’s been since you purchased the product. However, in case parts replacement is required, then the cost of these replacement parts will be charged to the customer

NOTE: The Panther Lifetime Service Warranty becomes void when there are signs of product tampering (as evidenced through the warranty sticker condition)

Voltage surge and fluctuations occur regularly in the Philippines, and can be caused by multiple factors: brownouts/blackouts, living near industrial areas or areas with high-powered equipment. Regardless of the cause, appliances nowadays are extremely vulnerable to damage when these voltage surge/fluctuations occur. As such, many people invest in voltage surge protection for their appliances to prolong its continued usage life

Here at Panther, we have multiple products under our Voltage Protection product line, which can suit your needs. Learn more here

We have a strict no return, no refund, and no cancellation policy for made-to-order products once the deposit has been made. Because Panther produces the product according to customer specifications, it would be very difficult for us to find another buyer who would have the exact same requirements.

NOTE: Panther starts production as soon as the customer signs off on the product specifications and has provided an upfront deposit

Step-down transformer brings DOWN the input voltage, so that the output voltage supplied to your equipment is LOWER than the original voltage supply. (Example: from 220V AC voltage supply, to the 100V/110V AC required by your appliance)

Step-up transformer brings UP the input voltage, so that the output voltage supplied to your equipment is HIGHER than the original voltage supply. (Example: from 110V AC voltage supply, to the 220V AC required by your appliance)

For a more detailed explanation, you can lean more here

Technically, yes. However, you run the risk of slowly damaging your appliance due to the constant “over” voltage supplied. We highly recommend that you use a transformer that provides the exact voltage requirement of your appliance, just to be on the safe side. For inquiries, you may contact us here

A transformer converts the voltage coming from the power supply (e.g., Meralco voltage supply is at ~220V – 230V AC) into another voltage, depending on the transformer specifications.

On the other hand, an AVR (Automatic Voltage Regulator) regulates and stabilizes the power supply in order to maintain a constant output voltage level for your appliance, so that the appliance is protected from voltage surge and fluctuations

Take note: Panther’s PVR and PVS series can serve both the purpose of the transformer and AVR; whereas the Panther PVE series serves a purely AVR function

Clicking sound: Every time you hear a click from your relay-type AVR, that’s the sound of the relay switching from one voltage range to another – this occurs when the AVR is forced to regulate the voltage supply.

Whirring sound: Every time you hear a whir from your servo-motor type AVR, that’s the sound of the servo motor working to regulate your voltage supply

So if you hear “noise” from your AVR, it simply means it’s doing its job well and your appliance is being protected from an instance of voltage surge/fluctuation. However, if the sound is continuous/nonstop, please contact us so we can provide an assessment on the item

The AVR is expected to heat up because the transformer inside is working. As long as you can touch the AVR, even if the heat is a bit uncomfortable, then that is normal.

In all three cases (UPS, Inverter Charger, Generator), the technology pulls power from a DC power source (battery) then converts it to an AC power supply. However, the difference with the Uninterruptible Power Supply is that it is able to near instantaneously take over the supply of power to the appliance in instances of power disruptions, thus preventing data loss and minimizing device damage due to incorrect shutdown.

On the other hand, Inverter Chargers and Generators would experience a “lag” time before it can accomplish the switch. However, keep in mind that Inverter Chargers and Generators have other advantages over the UPS, and would therefore be used in a different function altogether

The Panther UPS is easy to set-up – simply plug and use!

• Step 1: Plug in the UPS into a verified grounded 3-wire wall outlet.

• Step 2: Fully charge the UPS battery for 10-12 hours before use

• Step 3: Connect your equipment to the BACKUP outlets

• Step 4: Switch on the UPS by pressing the power switch

Metal extension cords provide excellent value for money for two reasons:

• Metal is sturdier and more durable, whereas plastic extension cords can crack easily when dropped or hit
• Parts are easily replaceable in metal extension cords. With Panther’s Lifetime Service Warranty, this can give your extension cord a new lease at life – thereby saving you money AND protecting the environment from waste. On the other hand, because of how the parts are interlinked in plastic extension cords, a broken part typically results in an unsalvageable plastic extension cord which would need to be thrown away and replaced

We do not recommend it as constant spark testing will damage the ammeter. However, if you need to conduct a spark test, please set it to the lowest possible voltage.

We highly recommend you charge one battery at a time. When batteries are charged in series by a single battery charger, there is no way to determine if both batteries are being equally charged. Although the current being applied to both batteries is identical, the two batteries may have differences in battery condition due to aging resulting in unequal battery voltages.

However, keep in mind that batteries used in series must be charged together as well, in order to ensure that the battery conditions remain the same

WARNING: If you charge two batteries in a series, wherein one battery is actually faulty, it could damage the “good” battery as well

This typically happens if the battery is defective – either due to a leak or a short. Try charging a different battery to see if the same problem occurs.

If the problem continues despite charging a completely different battery, please message us with the specific issues experienced. Otherwise, you can bring the battery charger to one of our authorized centers to have it checked and repaired using our Lifetime Service Warranty.

Keep in mind that there are two types of power inverters: Pure Sine Wave and Modified Sine Wave

A Pure Sine Wave Inverter is capable of running any type of equipment as the power supply it generates is similar to the power supply from our home/business outlets. As long as you use a right size inverter given the power consumption needs of your equipment, it should work fine. On the other hand, Modified Sine Wave Inverters are less efficient and are more susceptible to interference compared to Pure Sine Wave Inverter.

Most consumer electronics today work perfectly fine with Modified Sine Wave Inverters. However, certain devices are considered incompatible. These include ballasts, medical equipment, LED lights and LED TVs.

If you’re unsure whether your device would be compatible with a Modified Sine Wave Inverter, check out our article for more details. If in doubt, ask the equipment supplier as they would be the most well-equipped to identify your device’s exact requirements
