How to Check If a Power Bank Is Certified and Safe Before You Buy

In an era where smartphones have become an extension of ourselves, power banks are essential items. However, choosing a non-certified power bank not only results in poor performance or slow charging but also poses risks of short circuits, fires, or explosions.

Today, we will look at how to observe and verify that a power bank is safe and truly certified as follows:

1. Look for the TISI Certification Mark (Most Important in Thailand)

In Thailand, the Thai Industrial Standards Institute (TISI) has declared power banks as controlled products since 2020. Therefore, legitimately sold power banks must bear the TISI (มอก.) mark 2879-2560.

• How to check: Look for the TISI emblem on the device itself or on the packaging.
• QR Code verification: Below the TISI mark, there will be a QR Code. Use your phone to scan it and verify that the information in the system matches the power bank you have. (If it cannot be scanned or the information does not match, assume it is a counterfeit.)

2. Check the Label Information

A certified power bank must clearly display details in a readable formatnot just on a faded sticker or in foreign text. It must include the following:

• Capacity: Both the rated capacity of the battery cells and the actual output capacity.
• Power rating (Input/Output): Clearly specified Voltage and Ampere values.
• Manufacturer/Importer Name: A clearly identifiable company name that can be verified.
• Usage Warnings: Warning messages regarding heat or storage instructions.

3. Observe Build Quality

Manufacturing standards are often reflected in the design and materials:

• Seams: High-quality power banks have seamless, tight joints with no visible gaps or excess glue.
• Weight: It should have a reasonable weight proportional to its capacity. If it feels unusually light compared to its stated capacity, be wary of low-quality or counterfeit products.
• Surface/Material: The material should be heat-resistant, not thin, low-grade plastic that feels soft or fragile.

4. Purchase from Trusted Sources

Avoid buying power banks at abnormally low prices from online shops without a physical presence or reliable reviews.

• Official Store: Purchase from the brand's official store on e-commerce platforms.
• Reputable IT Retailers: Shops with a clear, verified presence in shopping malls typically screen products to ensure they meet standards before selling them.

5. Monitor Usage Behavior

Once purchased, observe these signs during use:

• Excessive Heat: While charging in or discharging out, the device should not become too hot to hold.
• Erratic Battery Percentage: The battery indicator should drop steadily, not jump or fluctuate drastically.
• Odor: If you smell burning or melting plastic, stop using it and unplug it immediately.

Summary: The safest way to buy a power bank is to always look for the TISI certification mark and verify it via the QR Code. Do not be tempted by cheap products with no clear origin, as the safety risks are simply not worth it.
