If you are buying a radio just for exams and rarely use it, you can simply buy a radio from other companies that can meet the requirements; but if the performance requirements are very high, this is unlikely. If in addition to taking exams you also use it to listen to programs, you should buy a slightly better one and consider Desheng radio. After all, Tecsun is a famous brand radio, so it is naturally unique in its design and manufacturing. In addition, Tecsun's after-sales service is quite good. Since the radio is broken, it will be difficult to repair it if there is no warranty.
Which is more convenient lithium radio battery or dry battery power? Personally, I think it's good if it's powered by dry batteries. Because the power consumption of the radio is not large, it is enough to usedry batteries to power it. If it is equipped with a transformer, this is also a good choice. If you find that dry batteries are not durable, another option is to consider purchasing rechargeable batteries.
It is not impossible to use lithium batteries for radios, but lithium batteries are more expensive and are mainly used in places with high power consumption and small size. If a lithium battery is installed in the radio, the price of the battery is included in the radio, so the price of the radio will be higher.
In terms of program, it is more convenient to use dry electricity. If the radio is discharged, dry batteries can be purchased at various stores. However, charging lithium batteries will be subject to certain conditions.
Tecsun R-9702 and Kailong KK-S60L are the same quality of radios, except that one uses rechargeable batteries and the otherbe dry batteries. I can't say which one is better? This may only depend on your usage environment and power supply preferences.
