Features

Solar Charging Function

This power bank does not support solar charging. It relies solely on AA batteries, making it unsuitable for situations where sunlight is the only available power source. You will need to carry spare batteries.

Pass-Through Charging Function

Pass-through charging is not supported. This means you cannot charge both the power bank (AA batteries) and your device simultaneously. You can only charge your device when the power bank has sufficient battery power.

Low-Current Charging Mode Function

There is no mention of a low-current charging mode. Therefore, it may not be suitable for charging low-power devices like wireless earbuds or smartwatches, as it could potentially damage their sensitive batteries.

Digital Display Function

Instead of a digital display, this power bank features a battery level indicator that uses green and blue lights to indicate the battery status. This provides a less precise indication of the remaining power compared to a numerical display.

Built-in Cable Function

This power bank does not have built-in cables. You'll need to carry your own USB cable to connect your device for charging. This might be slightly less convenient, as it requires an additional accessory.

Wireless Charging Function

Wireless charging is not supported. You'll need to rely on a traditional USB cable for charging your devices. This may be a limitation for users who prefer the convenience of wireless charging.

Ranked #19 out of 25 products in Category
2.1
Overall Rating

The ADCB POW1 is a basic, low-cost emergency power bank. It's limited by its reliance on AA batteries and lower output. It's suitable for short-term emergency use but not for extended power needs. Durability is questionable due to the plastic build. It is best for situations where a quick power boost is needed.

Capacity and Battery Life
1.0
This power bank relies on 4 AA batteries, offering limited capacity compared to dedicated rechargeable power banks. The actual capacity depends on the quality of the batteries used, making it inconsistent and less reliable for multiple charges.
Output Ports and Charging Speed
2.0
With a single USB output and a current of 800mA, the charging speed is quite slow compared to modern power banks. It lacks fast charging technologies like Quick Charge or Power Delivery, making it less efficient for newer devices.
Size and Portability
4.5
The compact and lightweight design makes it highly portable, fitting easily into pockets or bags. This is a significant advantage for users who prioritize convenience and minimal bulk, especially in emergency situations.
Input Charging Speed
0.0
This device does not have an input for charging itself. It relies solely on disposable AA batteries, which need to be replaced when depleted. This is a major limitation compared to rechargeable power banks.
Safety Features
2.0
While it includes a battery level indicator, detailed safety features like overcharge, over-discharge, and short-circuit protection are not explicitly mentioned. The reliance on AA batteries may also introduce additional safety concerns if low-quality batteries are used.
Durability and Build Quality
2.5
The product description mentions that the plastic feels a little cheap. This suggests that the build quality may not be very robust, potentially affecting its long-term durability, especially with frequent use or in harsh conditions.
Manufacturer Reliability and Warranty
2.0
ADCB is not a well-known brand in the power bank market, raising concerns about long-term reliability and customer support. The lack of detailed warranty information further contributes to this uncertainty.
Cost Performance
3.0
At $26.99, it offers an affordable entry point for emergency charging. However, the ongoing cost of replacing AA batteries and the limited functionality make it less cost-effective compared to rechargeable alternatives in the long run.
