In scenarios such as overseas cultural and tourism group Tours, international exhibition receptions, and cross-border corporate investigations, the battery life of wireless audio guide has always been a core concern for users – no one wants to encounter the embarrassment of device power outages during crucial tour guide sessions. With 18 years of experience in the industry, Yingmi explains that with its solid technology and market validation, it has delivered an outstanding performance in battery life and has become the trusted choice of many overseas customers.
I.From the perspective of overseas customer cases: Battery life is the core competitiveness of the audio guide
1.Tour Guide Records of European Scenic Spots
There is a travel company in Spain that receives tourists from various European countries all year round and specializes in in-depth tours of ancient cities along the Mediterranean coast. Before the tour guide equipment was changed, they were often teased by tourists: the tour guide would set off early in the morning, and the tour guide devices would often run out of power one after another just after noon. Tourists have no choice but to gather around the tour guide and listen to the shouts. Not only is the visiting experience discounted, but it is also easy for tourists to get lost. Especially during the hot summer days, the battery life of the equipment is even less impressive. Sometimes it runs out of power within five hours. Several times, the second half of the tour turned into a “silent journey”, with tourists constantly complaining.
Some government and business reception institutions in Poland have also encountered similar troubles. They often undertake inspection activities for multinational enterprises. Once, they received a German company for a factory visit. Unexpectedly, the power of the tour guide suddenly went out during the visit, forcing the technical explanation to stop. This not only disrupted the originally arranged process but also made the host feel extremely embarrassed. The real experiences of these overseas customers actually reflect the most core demand of wireless audio guides in actual use – whether the battery life is good or not directly determines whether the service quality is up to standard.
However, since these customers switched to the Yingmi audio guide, the situation has completely changed. The tour guide of that Spanish travel company led the tourists to visit the ancient city for 10 consecutive hours. The equipment was powered stably throughout the journey. From the church explanations in the early morning to the seaside viewing in the evening, the sound quality was clear and bright all the time. The government and enterprise reception institutions in Poland later conducted several full-day inspection activities. The tour guide did not need to be charged throughout the entire process, perfectly handling the entire explanation from the workshop production line to the meeting room communication. There was no more embarrassing interruption.
2.International exhibition scenarios: Battery life tests when multiple devices are used simultaneously
At the Dubai International Building Materials Exhibition, many participating enterprises encountered the same problem: the exhibition lasted for nine hours, with multiple sets of audio guides working simultaneously. Traditional equipment often ran out of power in the afternoon. However, the booth space is already limited and it’s impossible to provide enough charging sockets. Some enterprises can only have their equipment charged and used in rotation. As a result, when customers come to inquire, no one can introduce them in time with a guide, thus missing many potential cooperation opportunities.
The performance of the Yingmi audio guide at this exhibition was highly praised by all the participating enterprises. One exhibitor simultaneously operated 20 sets of equipment to receive international clients from 10 a.m. until 7 p.m. The battery of all the equipment was fully charged, and there was no need to worry about charging at all during this period. This strong battery life enables enterprises to focus on communicating with customers without constantly worrying about the device running out of power, and the reception efficiency is immediately improved.
II. Pain Points of Wireless Audio Guide Battery Life: In Which scenarios is it most likely to fail
1.Long-term scenarios: Battery life anxiety when used for more than 8 hours
Scenarios where the audio guide needs to be used for a long time, such as leading groups in scenic spots, enterprise inspections, and academic conferences, pose a particularly significant challenge to its battery life. The battery life of traditional audio guides usually doesn’t last more than six hours, which is far from meeting the usage requirements throughout the day. Frequent charging is not only troublesome but also requires extra effort to manage the charging matters, increasing the cost. More importantly, it can easily lead to interruptions in explanations, greatly reducing the user experience.
Among overseas customers, complaints from scenic spots and travel agencies are particularly numerous. The tour routes of many popular scenic spots are designed to last for 8 to 12 hours. Traditional tour guide device often run out of power just halfway through the journey. Tour guides have no choice but to carry spare equipment or charging devices, which are both heavy and cumbersome, seriously affecting work efficiency. What is even more worrying is that once the power of the tour guide is cut off, the risk of tourists losing contact with the group increases, which is equivalent to laying a safety hazard.
2.Extreme environments: Low temperatures and battery life challenges when multiple devices are used simultaneously
The reduction in battery life under extreme conditions is another major problem faced by overseas customers. In low-temperature regions like Northern Europe and Canada, the battery performance of traditional tour guide device will significantly decline, with the battery life possibly dropping by more than 30% all at once. In winter, when leading outdoor Tours, it simply cannot meet the demands. During large-scale events, the signal interference generated when multiple devices are working simultaneously will also cause the battery to drain even faster. The already insufficient battery life is now even worse.
In addition, when used in batches, charging management is also particularly troublesome. The charging interfaces of traditional devices are in a mess. Charging multiple devices simultaneously takes up a large number of sockets. It’s very troublesome to store them up and charge them. Not only does it waste time, but it’s also easy to damage or lose the devices. For institutions that need to frequently use interpreters, these problems have seriously slowed down the work pace.
III. Yingmi 007B: The Scenario Adaptation Approach for High-Endurance Benchmark Products
1.Core parameters: 10-hour continuous playback battery life guarantee
The Yingmi 007B self-service audio guide system has an outstanding battery life among wireless tour guide device. This product is equipped with a 1280mAh high-performance lithium-ion battery.
