Features

Solar Charging Function

Feature Description

A function that allows charging the portable power bank using sunlight. This is beneficial for outdoor activities like camping or hiking, where access to conventional power outlets may be limited. It offers an environmentally friendly way to replenish the power bank's battery.

About This Product

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'll need to carry spare batteries.

Pass-Through Charging Function

Feature Description

A function that enables charging both the portable power bank and a connected device simultaneously from a single power source. This is useful when only one power outlet is available, allowing users to efficiently charge both devices overnight or while traveling.

About This Product

Pass-through charging is not supported. This means you cannot charge the batteries while also using it to power a device. This limits its usability when you only have access to a single power outlet.

Low-Current Charging Mode Function

Feature Description

A function specifically designed for charging low-power devices, such as wireless earbuds, smartwatches, and fitness trackers. This prevents overcharging or damage to these sensitive devices by delivering a stable, low-current power flow.

About This Product

There is no mention of a low-current charging mode. Therefore, it may not be suitable for charging sensitive low-power devices like Bluetooth headsets or smartwatches. Using it may damage those devices.

Digital Display Function

Feature Description

A function that provides a precise numerical readout of the remaining battery percentage. This allows users to accurately gauge the power bank's capacity and plan their charging needs accordingly, eliminating guesswork associated with traditional LED indicators.

About This Product

This power bank lacks a digital display. There's no way to know the remaining battery life accurately. You'll have to guess or rely on the performance of the batteries to determine how much power is left.

Built-in Cable Function

Feature Description

A function that includes integrated charging cables (e.g., USB-C, Lightning) directly attached to the power bank. This eliminates the need to carry separate cables, reducing clutter and ensuring compatibility with a variety of devices. It's especially convenient for travel.

About This Product

This power bank does not have built-in cables. You'll need to carry your own USB cable, which can be inconvenient. Forgetting the cable renders the power bank useless. Always remember to bring a cable.

Wireless Charging Function

Feature Description

A function that allows wirelessly charging compatible smartphones and other devices by simply placing them on the power bank's surface. It offers a convenient, cable-free charging solution, ideal for quick top-ups at home, in the office, or while traveling.

About This Product

Wireless charging is not supported. You must use a USB cable to charge your devices. This is a common limitation for budget power banks. Wireless charging would have added to the cost.

SHOPSTAFF Rating Score

#23

Ranked #23 out of 25 products in Category

1.8

Overall Rating

This power bank is a very basic, low-capacity emergency charger. It's best suited for powering small USB devices or as a backup flashlight. The build quality is flimsy, and its charging capabilities are limited. It's a budget-friendly option for basic needs.

Capacity and Battery Life

1.0

Rating Criteria Explanation

The capacity of a portable power bank, usually measured in milliampere-hours (mAh), determines how many times it can recharge your devices. Higher mAh ratings mean more charges. Consider the battery capacity of your devices and choose a power bank with sufficient capacity to meet your needs. For example, if your smartphone has a 3000mAh battery and you want to charge it twice, a 6000mAh power bank would be a suitable starting point. However, remember that some energy is lost during the charging process, so it's always a good idea to have some extra capacity. Consider future needs as well – you might acquire devices with larger batteries later on.

Rating Comments

This power bank relies on 4 AA batteries, offering very limited capacity compared to lithium-ion power banks. It's suitable only for providing a small charge or powering low-energy devices. Expect very limited usage time.

Output Ports and Charging Speed

2.0

Rating Criteria Explanation

Examine the available output ports on the power bank. Does it have enough ports for your devices? USB-A is the most common, but USB-C is becoming increasingly popular and offers faster charging speeds with compatible devices. Also, consider the output current (measured in Amperes, A). Higher amperage allows for faster charging. Look for power banks that support fast charging technologies like Quick Charge (QC) or Power Delivery (PD). Make sure your devices are compatible with these technologies to take advantage of the faster charging speeds. Check the specifications to ensure the power bank provides enough current and voltage for each of your devices simultaneously if you plan to charge multiple devices at once.

Rating Comments

With only one USB port and unknown charging speed, this power bank is quite limited. It lacks fast charging capabilities and can only charge one device at a time. It's best for very basic charging needs.

Size and Portability

4.0

Rating Criteria Explanation

The size and weight of the power bank are critical, especially if you plan to carry it with you regularly. Consider how you will be using it. A slim, lightweight power bank is ideal for everyday carry in a purse or backpack. If you need a high-capacity power bank for extended trips, you might have to compromise on size and weight. Check the dimensions and weight specifications to ensure the power bank is comfortable to carry around. Think about where you'll typically store it – a small pocket, a backpack compartment, etc. Visualizing this will help you choose a size that works for your lifestyle.

Rating Comments

The compact size and lightweight design make this power bank highly portable. It's easy to carry in a pocket or bag, making it convenient for emergency use. This is one of its strongest features.

Input Charging Speed

0.0

Rating Criteria Explanation

The input charging speed determines how quickly you can recharge the power bank itself. A power bank with a higher input current (e.g., 2A or more) will recharge much faster than one with a lower input current (e.g., 1A). Consider power banks that support USB-C Power Delivery (PD) for even faster recharging. Pay attention to the type of input port (Micro-USB, USB-C, or Lightning). USB-C is generally the fastest and most versatile. Check if the power bank includes a charging cable, and if so, what type. If not, you'll need to purchase one separately. A faster recharging power bank will save you time and ensure it's ready when you need it.

Rating Comments

This device does not have an input for charging itself. It relies solely on replacing the AA batteries, which can be inconvenient and costly. There is no way to recharge the 'power bank' itself.

Safety Features

2.0

Rating Criteria Explanation

Safety is paramount when dealing with batteries. Look for power banks with built-in safety features such as overcharge protection, over-discharge protection, short-circuit protection, and temperature control. These features help prevent damage to your devices and the power bank itself, and they also reduce the risk of fire or explosion. Check for certifications like CE, FCC, and RoHS, which indicate that the power bank has been tested and meets certain safety standards. Reading user reviews can also provide insights into the reliability and safety of a particular power bank.

Rating Comments

Safety features are unknown, which is a concern. It's important to use high-quality batteries to minimize risks. Without specified safety features, there's a higher chance of issues.

Durability and Build Quality

1.0

Rating Criteria Explanation

The durability of a power bank is important, especially if you plan to use it outdoors or in harsh environments. Look for power banks with a rugged design and a sturdy casing. Some power banks are even water-resistant or dustproof. Consider the materials used in the construction of the power bank. Metal casings are generally more durable than plastic casings. Read user reviews to get an idea of how well the power bank holds up to everyday wear and tear. Think about your usage scenarios – if you're a frequent traveler, a more durable model will be a worthwhile investment.

Rating Comments

The build quality is described as flimsy, suggesting it may not withstand much wear and tear. The battery door issue is a significant concern. Expect a short lifespan with regular use.

Manufacturer Reliability and Warranty

1.0

Rating Criteria Explanation

Choose a power bank from a reputable manufacturer known for producing high-quality and reliable products. Established brands often have better quality control and customer support. Check the warranty offered by the manufacturer. A longer warranty period indicates that the manufacturer has confidence in the quality of its product. Read reviews and research the manufacturer's reputation before making a purchase. Look for information about their customer support and return policies. A reliable manufacturer will stand behind their product and provide assistance if you encounter any issues.

Rating Comments

Sxowihz is not a well-known brand, raising concerns about reliability and warranty support. There's limited information available about the manufacturer's reputation. Purchase at your own risk.

Cost Performance

3.0

Rating Criteria Explanation

Ultimately, you need to consider the cost performance of the power bank. Don't just focus on the cheapest option; instead, weigh the price against the features, capacity, safety features, durability, and manufacturer reputation. A slightly more expensive power bank from a reputable brand with better features and a longer warranty may be a better investment in the long run than a cheaper, lower-quality option. Consider the total cost of ownership, including the cost of replacing the power bank if it fails prematurely. Compare different models and brands to find the best balance of features and price that meets your needs and budget. Calculate the mAh per dollar to compare the energy density for the price.

Rating Comments

At its low price, this power bank offers basic functionality for emergency situations. However, its limited capacity, lack of features, and questionable durability make it a short-term solution. It's cheap, but don't expect much.
