Basike · Reviewed by Jersu · Published 2026-03-04
Based on a review by Jersu (accessed 2026-03-04).
Based on this review alone: buy it if you care about cost-effective with good value for money — just accept integrated cables only provide lower wattage (10-15w).
The reviewer recommends several power bank models, particularly praising Basike for its cost-effectiveness, Geonav for its portability and features, and Xiaomi for reliability. He stresses that the best power bank depends on a user's specific smartphone charging technology and daily needs, while also cautioning against generic models and emphasizing the importance of ANATEL certification.
This review compares various power banks, focusing on their cost-benefit, charging technologies like Power Delivery (PD) and Quick Charge (QC), and practical aspects such as portability and capacity. The reviewer also highlights common issues with inexpensive models, including misleading power ratings and poor quality accessories.
This Basike power bank is highly recommended as a top budget option for those seeking a reliable and cost-effective portable charger. It delivers 20W Power Delivery via USB-C, effectively charging iPhones, Galaxies, and Xiaomis, with a total capacity of 20,000 mAh providing three to four full charges for modern smartphones. While the integrated cables only offer 10-15W output, a separate high-quality USB-C cable will unlock its full potential. If you prioritize affordability and efficient charging for mainstream devices, this power bank is an excellent choice. However, if you require higher wattage from integrated cables or extreme portability, you might need to consider other models.

The reviewer recommends the I2GO power bank, possibly an Amazon brand, as a very good and cost-effective option at R$100. It has 10,000 mAh capacity and 20 Watts Power Delivery.
The reviewer strongly recommends Basike power banks, especially the 20,000mAh model, as a top choice for saving money due to its Power Delivery (20W) and 22.5W input capabilities. The I2GO 10,000mAh power bank, priced around R$100, is also highly praised as a very good, cost-effective option offering 20 Watts Power Delivery.
The reviewer highlights that most modern smartphones (Samsung, Apple, Xiaomi) rely on USB-C for charging and benefit significantly from Power Delivery (PD) technology. He notes that many cheaper power banks only offer Quick Charge (QC) via USB-A, leading to slower and less efficient charging for current devices.
The reviewer explicitly warns that power banks with very high Watt-hour capacities are prohibited on flights, emphasizing the need for official certifications like ANATEL for travel. He clarifies that despite some misinformation, large power banks typically exceed aviation regulatory limits.
The reviewer criticizes the thin, integrated cables commonly found on many power banks, explaining that they are typically of poor quality and cannot carry sufficient current for efficient charging. He estimates they deliver only 10-15 Watts, advising users to purchase separate, higher-quality cables for optimal performance.
The reviewer warns that many inexpensive, generic power banks fail to deliver sufficient charging power, often only reaching 10-15 Watts, and lack the Power Delivery technology via USB-C that modern phones require. Additionally, their integrated cables are typically too thin for effective charging, and sellers often do not disclose the actual wattage output.
The reviewer explains that while a Xiaomi POCO X7 Pro can achieve 90 Watts charging with its dedicated USB-A charger, connecting it to a generic power bank via a USB-C to USB-C cable will usually only deliver around 30 Watts. Users should be aware of their phone's specific technology and compatibility with power bank outputs to avoid disappointment.
The reviewer highly recommends Basike as a good, cost-effective brand that explicitly discloses wattage and has a market presence. Geonav is also strongly endorsed, with the reviewer and his acquaintances having used its portable, slim models for a long time, praising their 20W Power Delivery, Quick Charge features, and ANATEL certification for travel. He notes the importance of checking certifications for reliability.
