| Studies have shown that in the past year, global smartphone users spent a total of 2.3 billion hours on smart phones, and this figure will also continue to rise. Before the advent of next-generation battery technology, mobile power in the future is quite long For a period of time, it will be everyone's necessities.  We spend several hours a day on mobile phones, but many cell phones do not have good battery life. Take the iPhone X and Galaxy S9 two mobile phone industry benchmarks: iPhone X has been tagged on the official website for up to 12 hours. However, the iPhone X can only last less than 8 hours in actual use; the Samsung S9 is equipped with a 5.8-inch 2k display, but the 3000mAh battery capacity makes it difficult to maintain a full battery life. In addition to mobile phones, many people still have iPads, laptops, and even wireless headsets need to be recharged. For those heavy power users, the 5000 or 10,000 milliampere of mobile power on the market can't meet the demand. And this time we’re evaluating it. An unusually sized mobile power supply - Roman Sense 8'30000 mAh mobile power (Official price: 129 yuan)   There is no doubt that the most significant feature of Sense8 is that it can charge the iPhone 8 more than ten times when its battery capacity is up to 30,000 mAh. In addition, there is an interesting point where Sense8 and Sense family brothers name each other, Sense4 and Sense6. 10000mAh and 20000mAh respectively. Equipped with two output interfaces can also provide power for multiple devices, and one of them can also support 2.1A fast charging, which can help users to fill the mobile phone in a short time. Built-in Fit Charge Intelligent Adaptation Technology It can automatically detect the internal power supply IC of the mobile phone and tablet device, and automatically adjust the output power. For small digital products such as Bluetooth headsets and smart watches, it will intelligently enable the use of small current charging, which can be said to be retractable and free. The official said, to the sense 8 can be used once a week.   In terms of design, Sense8 continues Romeo's consistent design style. It is simple and low-key, and the whole body is made of white plastic. The four battery indicators each represent 25% of the power, and the user can press the side The power button provides easy access to the approximate amount of power remaining. At the beginning of charging or discharging, these indicators also flash automatically to display the remaining power in real time.  When you go out, in addition to considering charging devices such as mobile phones, you also need to consider charging the mobile power supply. The general mobile power supply on the market has only one Micro USB input port. If your phone is a Type C or Lightning connector, it means you It is also necessary to additionally charge the mobile power with a micro USB cable, so at least two wires are needed to make travel very inconvenient. The sense 8 has three input interfaces, Type C, Micro USB, Lightning, What type of phone is yours, you just need to charge a mobile phone to charge the mobile power.  The size of the Roman Sensation 8 is 167mm*81mm*32.8mm (L*W*D). It is longer and wider than an iPhone X, and it is slightly thicker than a dollar coin, basically one-handed holding pressure. Large. Its weight is as high as 672 grams, equivalent to the weight of four iPhone X. The benefits of high capacity are obvious, but it also brings some unavoidable shortcomings, such as being heavier than ordinary products. In addition, according to Mainland China regulations, if you carry a mobile power source with more than 100Wh and less than 160Wh ( For example, this type of mobile power supply, you need to negotiate with the staff. Normally, it is proof that the duty manager on the airport should prove that he can take the plane after permission. 
In terms of safety configuration, sense 8 is equipped with 10 protections against overcharging, overdischarging, overvoltage, temperature protection, short circuit protection, and protection against reverse protection. These are the standard features of the new Sense series mobile power supply. In short, you can rest assured of safety and stability. Real machine measured: high conversion, good output performanceSay so much, no matter if it is appearance or safety, the output performance of mobile power is the most important indicator to measure the pros and cons of this product. Then we borrowed two current popular mobile phones and output performance to Roman Sense8. Did a simple test.  
 The result was a little unexpected. Rome Sense8 not only supports Apple 2.1A fast charging, but also can charge most mainstream devices by FitCharge technology. The highest single-ended output power is actually measured. About 9.57W , And the maximum dual USB output power is achieved 12.81W, Even beyond the official calibration of 10.5W. This is only the test results of the test equipment is still in a higher power, I believe that in extreme cases the output power should come higher, it seems that Romer is a bit conservative for its calibration value. In addition, simply looking at the output power, the load current is not enough. A good mobile power supply should also have features such as stable output and high conversion rate. Next, we are still using our old rules to borrow Fistek's FT6301A programmable electronic load. The instrument performs a discharge test on it, and the final output power value and discharge curve are as follows.  Sure enough, as with the previous Rome Shi WA30, Sense8 inherited Romans mobile power conversion efficiency, output stable family characteristics. Through the test results tells us intuitively, Sense8 power output during the discharge process is relatively stable, which only appeared Several small-amplitude voltage fluctuations, the largest one being 0.128V, belong to the highest level of proficiency. The average voltage of the discharge process is stable at about 4.747V, the total battery capacity reaches 21.7657AH, and at the end of the test when the power is exhausted, there are obvious The self-shutdown action does not obviously reduce the output voltage with the decrease of the power. This action can effectively protect the internal circuit of the power supply and prolong the service life. After calculation of the measured data, the mobile power conversion rate = (4.747V*21.7657AH /111Wh) *100%≈93%, Efficient, efficient, and stable and safe. It is estimated that no one dares to mention the word 'virtual standard'! If a friend has doubts or cannot read it, please refer to our PConline evaluation standard. There is a reason to convince PConline mobile power evaluation specification. PConline evaluation room summaryLarge capacity, long battery life is the core selling point of the sense 8. Its stable output and high conversion rate are also unmatched by many mobile power sources of the same price. Fit charge, multiple input/output ports, support 2.1A high-speed charging and other features It is to further enhance its user experience. The only drawback is probably too heavy, but it can not be avoided, after all, 'can not have both fish and bear' it. It is worth noting that this large-capacity mobile power For only RMB 129, converted 1W Ma / 43 yuan, can be described as good value for money, it is recommended that there is a large capacity demand or friends who often go out for a long time can be prepared on one. |
