Hammer Test for LUXA2s power packWEB products

Tips in choosing the best power bank for your digital life!

LUXA2, a power, audio and holder solutions, their very own in-depth guide to the internal processes and workings that all their portable power banks undertake. Emphasis is placed on Quality, Performance and Reliability and how it is maintained through all stages of production to end user completion.

LUXA2’s extensive safety concept gives the Right Juice for Your Tech.

In modern day society, the use of smartphone, phablet ( large phone )and tablet devices is ever increasing and as a direct result, so too is their power consumption. These devices have become so integral to our everyday lives - just like our house keys, wallet and purse – simply forgetting to take one of these with you when you leave the house, will leave you feeling incomplete and uneasy throughout the rest of your day.

The Safety enhancing LUXA2 portable power banks with 2-year warranty and have extensive tests

LUXA2 has always believed in providing Quality power banks that are internally superior and aesthetically pleasing. We understand that ‘time is money’ and we want individuals to get on with their day with minimalistic fuss; therefore focus has been placed on the Performance of all our power banks to ensure fastest possible charge. LUXA2 power banks have also undergone vigorous testing for utmost Reliability, which is backed up with our standard two-year warranty. resellers and dealers wanted for our channel sales.


1. Battery Cell

Achieved by use of LG, Samsung and hi-grade battery cells, world-class circuit boards (figure 1), hand craftsmanship and undertaking of all relevant quality certifications.

4. Restriction of Hazardous Substances Directive (RoHS) Certification

All LUXA2 battery packs are fully compliant with the RoHS directive (figure 5) to ensure certain substances of high concern such as lead and mercury have not been used in any of our components.

Figure 5: RoHS certifications are labeled on all LUXA2 battery pack products.


1. Power Transfer Efficiency

Our battery packs are designed to provide high power conversion rates which is achieved by the use of high-class board circuitry and chipsets (figure 6) that enable them to optimize efficiency and durability.

Figure 6: LUXA2 power banks provide up to 90% energy efficiency compared to the average 75% offered by standard power banks

2. Input/Output Performance

LUXA2's power bank circuit boards goes through rigorous input/output testing (figure 6.1) to ensure that devices are charged at the optimized state, meaning that whatever the stated input/output performance (figure 6.2), you're guaranteed to know that the performance is constant to ensure fastest possible charging times.
