Large capacity and good value for money! Comparing two popular mobile battery models from ADATA

ADATA Chosen for High Quality

ADATA Technology is a semiconductor and electronics manufacturer established in May 2001 and headquartered in Taipei, Taiwan. DRAM modules and SSDs boast the second largest market share in the world. There are large-scale production facilities in Taipei, Suzhou, China, and Sao Paulo, Brazil. Products bearing the ADATA brand name are sold in over 70 countries around the world. Since ADATA's SSD won the top share in Japan in 2012, many users have chosen ADATA's products for their high quality and affordable prices. The company's product lineup also extends to mobile batteries. Both P20000QCD and P10000QCD are attracting attention as high-quality items with large capacity, excellent portability, and affordable prices, now that many devices can be charged with mobile batteries.

Comparing two popular mobile battery models

The battery capacity is 20,000 mAh for the P20000QCD and 10,000 mAh for the P10000QCD. The size of the main body is 365g for P20000QCD and 175g for P10000QCD. Although there is a nearly double difference in battery capacity, the estimated selling price is around 2800 yen for the P10000QCD, and the P20000QCD is around 3200 to 3400 yen, which is thin. There are three color variations, black, white and blue. Since the features introduced below are common to both models, as an index when comparing both models at the stage of serious consideration of purchase, first of all, "P10000QCD with emphasis on size" and "P20000QCD with emphasis on capacity" are used. can be drawn separately.

Compatible with 6 types of quick charging methods

First, let's introduce the features common to both products. Both P20000QCD and P10000QCD are equipped with a quick charge function. One thing to keep in mind is that there are currently various charging methods for quick charging. If the products do not match each method, the merit of the function cannot be utilized, and it will be charged slowly at the normal speed. ADATA's mobile battery supports a total of 6 types of fast charging technology, including USB PD (Power Delivery) 3.0, which is widely used, Qualcomm QC 3.0, MTK PE1.1, Samsung AFC, HUAWEI SCP & FCP, and OPPO VOOC. It's an item you can rely on in emergencies when you want to charge your device quickly. Both products are equipped with multiple USB ports of different types so that multiple devices can be charged at the same time. USB-C supports both input and output. It has two USB-A type ports. The P20000QCD also has a microUSB port for charging this unit, but pass-through charging is not supported. A maximum output of 18W can be obtained when connected to USB-C. You can charge various devices that support USB PD, but considering the balance, I think it is suitable for charging smartphones such as iPhones and tablets such as iPads. You can comfortably use wireless earphones, headphones, and smart watches that can be charged at a lower output. Apple's latest smart watch "Apple Watch Series 7" is the first Apple Watch to support USB-PD compatible rapid charging, with the connector on the power adapter and mobile battery side being USB-C. If you carry the "Apple USB-C Magnetic Fast Charging Cable" that comes with your watch, you can rest assured even if your Apple Watch's battery level is low on the go. Matching with the compact size P10000QCD is very good.

Flexible and safe to use

　There is a digital display counter on the front side of the main unit. While checking the remaining charge on the mobile battery side, you can efficiently charge as much as you need. As a safety consideration, both the P20000QCD and P10000QCD are equipped with a protection circuit to prevent overcurrent and heat-up due to overcharging. The package includes a USB-C/USB-A cable for charging the main unit. In order to charge other devices with this unit, I would like to prepare a charging cable that suits each device. When carrying smartphones and tablets for business trips, business trips, etc., carrying the included power adapters for power supply and charging can make the luggage bulky and the management of the equipment tends to be complicated. Especially when traveling for a short period of time, I want to reduce the amount of luggage as much as possible. In such a case, if you have one ADATA mobile battery that can handle charging of various devices, you will feel reliable. ADATA's P20000QCD and P10000QCD should also be the best choice for those who work outdoors for a long time and cannot secure a power supply all day long, because of their large capacity and high portability.
