I bought one, two 7# batteries, modified it and added a 5F supercapacitor, basically no more power outages, in fact, two batteries can also standby for a long time   Details Published on 2019-11-15 14:04

This one is broken and has no markings. It's really watery.

I bought a Huawei one, and after using it for less than half a year, the vital signs data no longer displayed, and I could only use it as an electronic scale (I guess the chip for measuring vital signs was broken). I took great pains to disassemble it a few days ago, and wanted to replace the chip, but the silk screen on the chip was worn off, and I didn't dare to replace it.

What model is Huawei? Is it CH8? I have a white one, which was given as a gift when I bought a Honor phone. It never displays any vital signs data and can only be used as an ordinary electronic scale.  Details Published on 2019-11-13 12:59

Ordinary polymer lithium battery, just replace it. You can use an old mobile phone battery as long as it can fit.

It's not broken, the battery is dead, I don't think it's accurate, the workmanship is too rough

It is probably a Hawthorn product. As for the accessories, the words have to be erased, which means it is too small a company. The protection is to prevent you from changing it yourself.

Huawei is not a small company, right? Also, Huawei has dismantled many products, and the silk screens of many chips have been worn off. This is a kind of product protection, which is understandable.  Details Published on 2019-11-13 17:16

I have one too, it's still working, but I think the accuracy is a bit problematic.

The accuracy requires finding the correct position, otherwise there will be errors in consecutive tests.  Details Published on 2019-11-13 14:09

The product manufacturer uses purchased battery packs

There is a problem with the packaging process of the battery. At least from the appearance, the packaging is not very standardized and the output lines are too messy.

It is indeed too messy, there is no way to repair it, it cannot be put back together after being disassembled, and there is just ordinary transparent tape inside,

Just find a single-cell lithium battery that can fit in and try it. Various household scales are devices that are used occasionally, and it is a stupid design to use lithium batteries to power them. The self-discharge of lithium batteries cannot be ignored here, and there is also the problem that the lithium battery will run out of power after a long period of non-use and the protection board will enter the protection state. Moreover, charging the scale is also very troublesome, and the wires may trip you up. Using dry batteries to power the scale, you can replace the battery every two to three years or even longer, and the cost of the equipment is lower than using lithium batteries. This is the right way.

Yes, it feels that using solar energy is useless. It is really a thankless task. I have personally tested it: lol

Solar energy design is also not appropriate, because the design requirements for the appearance structure will be much higher, and there are requirements for the placement, and the light intensity must be guaranteed. More importantly, the design of solar cells will basically use batteries for storage and backup, and the problem of batteries is naturally unavoidable. This type of product uses dry batteries.  Details Published on 2019-11-13 16:59

More importantly, the design of solar cells will basically use batteries for power storage and backup, and the problem of batteries is naturally unavoidable. For this type of product, it is better to use dry batteries. I bought a weight scale, and I don’t want any that are not powered by dry batteries. I bought my weight scale during the 618 period in 2015. It has been 4 and a half years now. The two No. 7 dry batteries have never been replaced. I used a multimeter to test it some time ago, and it doesn’t need to be replaced in the short term.

Teacher, I bought this solar panel 3 months ago. I put it on the windowsill everyday, but it ran out of power. After listening to the teacher, I think I need to buy dry cell batteries. This is really just for show. I have another lesson.  Details Published on 2019-11-13 19:55

No, that's not right. Huawei has become so big and it makes its own chips, but it still has to polish its products. Isn't polishing something that only small companies do?  Details Published on 2019-11-14 14:00

Huawei's own chips are not many, mainly concentrated in the backbone communications field. Consumer chips are only mobile phone basebands and some communications terminal products. Most Huawei products do not have their own chips. The most common place to see Huawei HiSilicon chips is routers. As for electronic scales, there is no possibility of Huawei chips.

It is placed next to the windowsill, and you have to put it on the ground when you need it, and then you have to put it back to the windowsill after use. It is intolerable just to think about it. It is not an exaggeration to say that it is a stupid design.

I agree with it. You can only know it after you have experienced it. When I bought it, I had all kinds of thoughts and thought about it. The result is predictable. I really only wanted to do one thing and thought I would not have to worry about the electrical issues. But  Details Published on 2019-11-14 22:38
