Many people wonder why I always carry a telescope on a business trip.
Because they are engaged in the work of wind power, solar power generation, these power stations are generally built in the desert, Gobi, islands and other places, desolate but the scenery is infinite. I used it to go to the mountain in the Gobi Desert; use it to see the Taihang Mountains after heavy snowfall in Hebei; use it to see the offshore oil that used to fight Vietnamese at sea in Sanya; and in the Paracel Islands, to see the speed of nearly 100 kilometers per hour.

Cost-effective Forester 8x32 telescope with high version
Telescopes are very popular in Western families. Every home, if conditions allow, should be equipped with a telescope, of course, not the kind of Taobao goods.
How to choose the size of the telescope?
If you go out and pursue a certain level of imaging quality, the 8X32 roof telescope is more suitable. Compared to the Paul mirror, the roof mirror is small in weight, light in weight, but it must have a higher cost to achieve a certain image quality; Paul mirror is large and high-weight, but the structure is simple, and the cheap Paul mirror can achieve good results. The imaging quality. The method of distinguishing between the Paul mirror and the roof mirror is very simple. It is to see if they are centered on the objective bus and the eyepiece on a vertical bus. If it is, it is the roof mirror; if not, it is generally Paul mirror. Of course, the more expensive the telescope is, the better it is. For example, the three big mirrors in foreign countries can easily exceed one million. This 8X32 mirror, if you do not want to spend a lot of money, spend a few hundred dollars to play, you can generally consider Forester 8x32 high version (558 yuan) or wins 8X32ED version (940 yuan). If you are interested in telescopes, you can go to the Shepherd Astronomical Forum and the Beiguo Optoelectronics Forum. This 8x32 high-quality forest human telescope uses a 3-piece objective lens, a focus lens, a set of high-precision roof prisms, and four 3-piece eyepieces. The coating is configured so that all glass-air contact surfaces are plated. AR coatings with reflectance as low as 0.4%, roof prisms with dielectric and phase films. The overall optical configuration level has reached the ultimate in domestic non-ED roof telescopes, unless the use of ED objective lens or flat lens between the roof prism and the eyepiece, it is difficult to improve the space optically. The overall light transmittance is about 85%. The optical performance can be described with 3 words: bright and sharp. This telescope is very good for even the most discerning users. Compared with the even more expensive Paul Prism telescope of the same price, it is no less. In addition, by coating all surfaces with a low-reflectance anti-reflection coating, the roof prism plating dielectric film can maximize the light transmittance of the whole machine, making the image more bright, the color more realistic, and the higher brightness. It means that more photons stimulate the optic nerves, and the sharpness of imaging can be significantly improved under low light conditions. The only drawback is that the telescope's image area is relatively small.
8x32 version of the optical structure
This flashlight is a well-known product in the flashlight lovers, but unfortunately it has been discontinued.
The flashlight should be considered a family standing item.
From a practical point of view, whether you are on a business trip or in a family, you can generally suggest preparing a small straight flash with a 18650 battery. The small size, light weight, and brightness are enough. Why use 18650 battery? Generally, the flashlights of batteries No. 7 and No. 5 are often made of nickel-hydride batteries. The voltage is low and the battery power is low, causing the brightness and life of the flashlight to be unsatisfactory. Generally a high-energy 18650 battery's power is equivalent to about 3 batteries on the 5th. In fact, some 5th batteries have begun to use lithium batteries with microtransformers (lithium batteries have a charge-off voltage of 4.2V or 4.35V, which is much higher than the charge-cutoff voltage of nickel-hydrogen batteries).
The 18650 battery is the highest volume production type battery currently available. Tesla's electric car is driven by thousands of such batteries (Matsushita 18650 battery). When buying a flashlight 18650 battery, we recommend that you choose Japan's Panasonic or Sanyo (Panasonic has already purchased Sanyo's battery business) or South Korea's LG, Samsung's battery, Taobao on a lot, generally fewer fakes, the best capacity 3200-3500mah. The price goes up and down.
The brand of flashlights, generally like fenix this big brand is certainly good. However, if it is only for daily use and the pursuit of cost-effectiveness, such as the Hawkeye X2, Pants S2+, Trailblazer C23, and Siketer DS20 these small straight are very good. If you are interested, you can go to the flashlight enthusiasts forum to learn more.
In addition, when buying a flashlight, it is not recommended that you buy the kind of 18,650 flashlights that cost between RMB 20 and RMB 30. This type of flashlight is often not over-charged. You can use your 18650 battery to discard it after several uses.
The battery life of this small straight use 3350mah battery is about 2h45m at maximum brightness.

16000mah capacity, insert a 5W LED light bar, light a dozen hours without problems.
Millet charging treasure just came out, it is simply the existence of God, directly to the brand charging treasure prices pulled a big chunk down. Later, when three battery versions of the 10000mah charging treasure were used, the Panasonic 18650 lithium battery, which was very expensive at the time, was used. The retail market price of these three Panasonic 18650 batteries has already surpassed the price of this rechargeable battery.
Charging treasure this product must not buy a small brand, or to spread the goods, Taobao goods. Because Baobao's security and other electronic products are very different. Lithium batteries themselves have a high level of electricity, and when they are short-circuited, they are very prone to burning and even explosions. Poor quality charging treasures are often able to save on the safety of charging treasures. The big brand charging treasure is of good quality, long life, and many times of charging, so it is more cost effective than inferior charging treasure.
For ordinary consumers to buy charging treasure, first, pay attention to choose a big brand; Second, pay attention to charging treasure battery (non-polymer battery), the market is generally a better battery is Japan's Panasonic, Sanyo, South Korea's LG, Samsung, These batteries have good consistency, many times of charging, long life, and small internal resistance, but the price is much higher than domestic batteries. Using these four battery charging treasures, the general quality will not be too bad, manufacturers will generally come up with publicity.

(5) FLUKE 15B+ Multimeter
Fluke (FLUKE) F15B + digital multimeter handheld multimeter automatic range with backlight instrumentation 529 yuan FLUKE in the multimeter's status, is equivalent to Apple's mobile phone in the mobile phone industry status. Jingdong direct link FLUKE's position in the multimeter is equivalent to Apple's position in the mobile phone industry. FLUKE's multimeter is a dream lover for many electronics engineers.
The voltage and current of the power industry are much higher than that of home electricity. Every time the measurement is made, the heart is very scared, especially for me. Every time the high pressure is measured, one cannot wait to pray to all the gods on Earth. This multimeter is actually accurate, but it can measure high current, high voltage, and security is very good. The quality of the homemade multimeter is uneven, and nobody will joke about his own life. A few hundred volts of voltage can instantly kill an elephant.

ANKER 50W Multi-Port USB Charger
Usually take up to three USB charging ports at the same time (two mobile phones, one charging treasure, and sometimes flashlight batteries, shavers), if anyone comes to look, it is four. Previously on business trips, the charging device was plugged into the notebook's USB port. Since the notebook board was burned once, it was bought by the 6-port charger. The nightmare is finally over.
Anker's charging head is very famous in Europe and the United States, Japan, the quality is very good, but the price is a bit expensive, after all, foreign brands.
Generally, when purchasing a multi-port charger, it is necessary to pay attention to the maximum charging current provided by the single port, as well as to determine the number of charging ports. In general, it is usually better to use one or two more charging ports for backup.
