Ranked #15 out of 25 products in Category

2.6

Overall Rating

This DIY power bank box offers a customizable solution for users who want to build their own power bank. However, the plastic build and lack of included batteries may limit its overall appeal and durability. It's a budget-friendly option for DIY enthusiasts.

Capacity and Battery Life

3.3

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

The battery life depends entirely on the user-supplied 18650 batteries. This allows for customization, but also requires the user to source and install the batteries themselves. Capacity is limited by the 20000mAh maximum specified.

Output Ports and Charging Speed

3.0

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

Features dual USB output ports, but lacks advanced charging technologies like Quick Charge or Power Delivery. The 2A output is adequate for most devices, but charging speeds may be slower compared to modern power banks.

Size and Portability

3.0

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 size is reasonable considering it houses 8 x 18650 batteries. However, the plastic construction may not be as durable as other power banks, making it less suitable for rugged use.

Input Charging Speed

2.5

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

The power bank supports Micro USB, Phone, and Type-C input, but charging speed is limited by the 2A input. It lacks support for faster charging technologies like USB-C Power Delivery, resulting in longer recharge times.

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. Given the low price and unknown brand, it's difficult to assess the level of protection against overcharging, over-discharge, and short circuits. User reviews suggest potential issues with build quality.

Durability and Build Quality

2.0

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 plastic construction raises concerns about long-term durability. User reviews mention issues with the case not closing properly and clasps breaking easily. This power bank may not withstand daily wear and tear.

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

LHIABNN is an unknown brand with limited information available. There is no mention of a warranty, raising concerns about product reliability and customer support. Purchase at your own risk.

Cost Performance

4.0

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 a very low price, this DIY power bank offers a cost-effective solution for users who want to build their own power bank. However, the lack of included batteries and potential durability issues should be considered.
