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 device does not support solar charging. It relies solely on manual cranking to generate power. Solar charging would have added to its versatility, but it is not included. You will need to use the hand crank.

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

This device cannot charge another device while being charged itself, as it does not store any energy. It only provides power while the crank is being turned. Pass-through charging is not possible with this design.

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 specific low-current charging mode. Given the limited and inconsistent power output, it may not be suitable for charging sensitive low-power devices. It is not designed for delicate electronics.

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 device does not have a digital display. There is no way to know how much power you are generating or how much charge your device is receiving. You will have to guess the charging status.

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 device does not have a built-in cable. You will need to supply your own USB cable to connect your device. This is a minor inconvenience, but it is something to keep in mind. Do not forget your 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

This device does not support wireless charging. You must use a USB cable to charge your device. Wireless charging is not an option with this hand-crank charger. You will need a cable.

SHOPSTAFF Rating Score

#25

Ranked #25 out of 25 products in Category

1.4

Overall Rating

This hand-crank charger is a very basic emergency power solution. Its low price reflects its limited functionality and questionable durability. It's suitable only for short-term emergency use and lacks the reliability of higher-end power banks. Expect a short lifespan with limited charging capacity.

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 charger does not have a battery. It relies solely on manual cranking to generate power, offering minimal and inconsistent charging capacity. It's only suitable for very short bursts of power when absolutely no other option is available.

Output Ports and Charging Speed

1.0

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 standard USB port and a low output current of 600mA, charging speeds are extremely slow. It's not suitable for modern devices that require higher amperage for efficient charging. Expect very slow charging times.

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

Its compact size and lightweight design make it easy to carry in a pocket or backpack. This is one of its few strengths, making it a convenient option for emergency situations where space is limited. It is very portable.

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 charging speed as it is charged manually via the hand crank. There is no way to pre-charge or store energy within the device itself. It is not rechargeable.

Safety Features

1.0

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

Given the lack of detailed safety information and the low price point, it's unlikely to have advanced safety features. Basic overcharge protection may be present, but it's not guaranteed. Use with caution and monitor closely during use.

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

Customer reviews frequently mention the product falling apart after only a few uses. The use of ABS plastic and copper wire does not inspire confidence in its ability to withstand regular wear and tear. Expect a very short lifespan.

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

TOPINCN is not a well-known brand, and there is limited information available about their reliability and warranty support. Given the negative customer reviews, it's unlikely that they offer robust customer support or a reliable warranty.

Cost Performance

2.0

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

While the price is very low, the poor build quality and limited functionality make it a questionable value. The effort required to crank the device for minimal charge makes it less appealing than even a basic power bank. It is cheap, but not effective.
