**Foreword**
A while back, the Samsung Galaxy Note 7 made headlines for its battery issues. Recently, the Apple iPhone 8 faced similar concerns. It seems that battery safety is becoming a bigger concern than ever before. In our daily lives, we often don’t think much about it — we just charge our devices and throw away the old ones without a second thought.
But when it comes to air travel, things are different. You can't just toss your power bank out the window. That’s why the Civil Aviation Administration of China (CAAC) has strict rules regarding portable power banks. Carrying one on a plane isn’t as simple as it used to be. You have to meet specific regulations set by the CAAC and also comply with the policies of the airline you're flying with.
As an average consumer, it's hard to keep up with all these rules. If a power bank has sufficient capacity and is clearly labeled as safe for air travel, it’s definitely a good choice.
**Unboxing**
▼ The package was shipped via YTO Express and came with an SF tape — funny, right?
â–¼ Inside, the power bank was wrapped in bubble paper.
â–¼ After removing the bubble paper, I saw the packaging of the power bank. The top shows the brand and product name, while the middle has some colorful design and features listed next to it.
â–¼ The specs include 5V 2.1A input and a weight of 360g.
▼ There’s a small orange label in the lower right corner indicating it's suitable for direct boarding.
â–¼ The side of the box shows the available colors.
â–¼ Detailed specifications are listed on the back:
- Name: Power Bank
- Cell Capacity: 20000mAh
- Product Family: A20
- Dimensions: ~150x64x23.5mm
- Weight: 360g
- Input: 5V/2A (Max) via Micro USB
- Output: 5V 2.1A
- Colors: Red, Gray, Blue, White
â–¼ The design allows you to open the case and see through a plastic window inside the power bank.
â–¼ The side pages describe the buttons and interfaces of the power bank.
â–¼ The pull-out design reveals a transparent plastic shell containing the power bank.
â–¼ Inside, there's the power bank itself, a short Micro USB cable, and the manual.
**Exterior**
â–¼ The white color is very elegant, and the black part on top gives it a nice contrast.
▼ At the bottom, there's the Taipower logo. The white isn’t pure white — it has a frosted texture with subtle color variations.
â–¼ The top has the power button and LED indicators.
â–¼ Pressing the button shows the remaining power through four LEDs.
â–¼ The front and back are similar, with large areas of white space.
â–¼ The capacity is printed on the bottom.
â–¼ The top has a label for the interface.
â–¼ The power bank is quite thick, with three layers and a raised center section.
â–¼ On the front, there are two USB-A ports and one Micro USB charging port.
**Testing**
â–¼ No-load voltage measured at 4.98742V.
â–¼ Stepping current test showed a maximum output of 4.72V at 2.8A, totaling 13.2W.
â–¼ Another no-load voltage reading was 4.98869V.
â–¼ Stepping current test again showed 4.8V at 2.8A, totaling 13.4W.
▼ Charging an iPad Air 2 reached around 2.3A, supporting Apple’s 2.4A charging mode.
â–¼ Another interface behaves similarly.
â–¼ Charging a Xiaomi 6 was normal, with around 8.6W of power.
â–¼ The other interface is similar to the first one.
â–¼ Using both interfaces together resulted in a low voltage drop and a total power of around 11.5W at 2.6A.
â–¼ When charging, the current was around 1.9A.
â–¼ Discharging at 5V 2.4A simulated charging an iPad Air 2, resulting in 65.88Wh, with a conversion rate of approximately 89.03%.
▼ The charging curve shows a dip in the middle — not sure what caused it. Total time was 10 hours and 2 minutes, consuming 89.53Wh, giving a charging efficiency of 82.65%.
â–¼ Final weight measurement came in at 366g, very close to the advertised 360g.
**Summary**
1. The appearance of this power bank is similar to other recent models from Taipower — they use a plastic shell with electroplating, making it shiny and colorful.
2. It has dual-output ports and a single-input port, with a maximum output of around 12W and input of 10W. It supports Apple 2.4A charging and has excellent conversion rates. It works well for two iPhones, but may struggle with two iPads.
3. The input port is still Micro USB, not Type-C — a bit disappointing. The plastic coating might wear off over time.
4. Importantly, this power bank is clearly marked as safe for air travel, likely meeting CAAC requirements. If not, it's easy to file a complaint.
Thank you all!
