Last week we talked about whether it is possible to leave the charger in the outlet. This material aroused serious interest on the part of our readers, and we decided that it would be a good idea to continue the topic by telling you about high-quality adapters and charging cables that you can and should purchase for your smartphones. Let’s make a reservation right away: not all of the presented copies will cost the same as the original, some will cost even less, and their quality will definitely not be worse. If you use inexpensive Chinese wiring or accessories that have long been scrapped, then you should definitely study our article and make your smartphone happy. In addition, we added a couple of nice little devices that will definitely come in handy. Happy shopping!
Selecting high-quality cables and charging adapters
How to choose a cable for charging your smartphone
A high-quality wire can last you not one or even two years, but much longer.
It is a mistake to believe that accessories, in particular charging cables should cost a lot of money - like Apple. But it’s also not worth buying anything. Both adapters and cables, first of all, should be from well-known manufacturers. UGreen is one of the favorite manufacturers among readers of our Telegram chat. Many people recommend this particular brand because its accessories last for years and do not fray. We found this example: there are two colors to choose from, as well as 4 length options from 0.5m to 2m.

Nylon cables are less susceptible to wear and tear, which is why they are loved
And there is also this UGreen cable : a version with Type-C, made in an angle. In fact: not all conventional plugs are convenient, so this solution has a right to life. It is very flexible, bends well, and due to nylon it is almost not susceptible to cracks. There are options for 0.5m, 1m and 2m.

Part III. I will cut, I will burn
TL;DR The current-carrying conductors turned out to be AWG27 both in resistance and cross-section. The core material is copper, both based on resistance and according to a test on a gas stove. Insulation and braiding burn and support combustion.
Conductor calculation based on linear resistance
From the given figures of lengths (1, 2 and 3 m) and resistances (0.44, 0.78 and 1.15 ohms) it is clear that the resistance
increases in proportion to the length of the cable, if you subtract approximately 0.08 ohms* for two connectors (*apparently, the typeA connector here is a little better than mine The test was lousy and was also enough for typeC).
And it is approximately 0.36 ohms per meter of cable or 0.18 ohms per meter of core (there are two of them). From the reference table, this corresponds to AWG27.
Calculation of a stranded conductor by total cross-section
Well, let's cut! Four veins are visible, with the black and red ones being noticeably thicker.
We count the conductors on the black core - 20 pcs.
And we measure with a micrometer. here the repeatability of measurements on one core is ideal. But different cores are slightly different - 3 measurements of 0.079, one of 0.077, one of 0.080 (I measured 5 cores in total)
Additional Information
The online calculator gives
Mathematical expectation .0788, standard deviation σ(X)=9.8*10**-4 mm Confidence interval +-3σ(X) = +- 0.003 mm That is, the diameter value is in the range from 0.076 to 0.082 mm The cross-sectional area of the conductor is in the range from 0.0045 to 0.0053 sq. mm Total area of 20 cores from 0.09 to 0.11 sq. mm
You will laugh, but based on the cross-sectional area - also AWG27
. I'll be honest, I'm happy with this match.
Among other things, this is evidence that we have copper.
Test by fire
Both braiding and insulation burn and support combustion. No one, however, promised anything else. The braid melts
Insulation - no, decomposes
A single wire is melted with gas and coated with black oxide. This is copper (we already found this out above). Aluminum burns in such a situation, iron does not melt in gas.
USB Type-C adapter
Small adapters like these are always useful around the house.
Sometimes there are situations when you absolutely need to connect a microUSB cable to a smartphone that has Type-C installed. What to do? The solution is simple: always keep a Baseus microUSB to Type-C adapter nearby. Believe me, this little thing will never be out of place in your backpack. By the way, the seller has the option of an adapter from USB to Type-C, which is also sometimes useful.

The adapter from Vention is quite lightweight - much lighter than other analogues
A 20 W adapter has long ceased to be a luxury - it is a completely common gadget used by all technology lovers. You will say that there are more powerful adapters - of course, we will talk about this later. If you are not chasing too fast charging, then you should take a closer look at the adapter from Vention : the seller offers a choice of the adapter itself or a unit with a Type-C/Lightning cable in addition. So to speak, any whim for your money.

Specifications
According to the store
- Cable length: 1m = 3ft 2m = 6ft 3m = 10ft.
- The aluminum connector and nylon braided cable provide greater durability, easy storage and tangle-resistance.
- Full charging and data syncing compatibility with SE, 6s / 6s Plus / 6 / 6 Plus / 5s / 5c / 5, Pad Air / Air 2, Pad mini / mini 2 / mini 3, Pad (4th generation), iPod nano (7th generation) and iPod Touch (5th generation), very fast charging, ultra-durable, ultra-resistant.

There are two versions for this adapter
We can’t say enough about Baseus: accessories from this brand are the first to come to mind when you need to buy something high-quality for your smartphone. Will 30 W of power be enough for you? I think quite. The adapter has three slots at once: 2 conventional USB and 1 Type-C port. If this is too much for you, then choose the USB + Type-C option - it will be a little cheaper.

There's still not a scratch on my white Baseus adapter
There is an option from Baseus with two ports that is a little cheaper. 10 W of power is also an indicator. It is slightly lighter than the previous adapter, but it also has built-in overheating protection, which works thanks to a special chip. By the way, despite the glossy finish it does not scratch: my adapter is still like new.

Stupid things we do with our smartphones
Powerful phone charger
I travel often and try to take only the things I need in my hand luggage. Carrying a small but weighty adapter for a Huawei laptop with me every time does not suit me, because other adapters also travel with it. And I found a cool solution: a powerful 100 (!!!) W adapter from Baseus with four sockets at once. 2 Type-C and 2 USB are what I need every day.
The block is quite heavy, but you save a lot of space in your luggage
This is GaN charging , it can withstand and conduct higher voltages and higher temperatures than conventional silicon ones, and accordingly the heating issue is not so acute for them. By the way, if 4 ports are too much for you, then take the option with one Type-C - you won’t regret it. The seller also includes a branded Baseus cable as a gift.

Description
There are no complicated technical issues, everything works extremely simply. The magnetic charger consists of 3 parts: the wire itself, the magnetic contact pad and the USB connector. The built-in magnetic connector begins to attract attention already at a distance of 4-6 cm, securely fixed to the phone, providing a strong connection. Even if you lift your phone by the wire, the magnetic connector will not come off and will continue to work.
Let's look at the main pros and cons.
Advantages:
- the risk of port damage is reduced;
- eliminates spontaneous rupture during operation;
- does not damage the connector contacts;
- charging speed.
Flaws:
- sticks out a little, it can’t always be placed in a case, because of this the appearance of the phone deteriorates;
- if the wire is fixed by something, then the magnetization may be incomplete, and then it will begin to overheat and subsequently this will lead to breakdown.
Internal cord parameters
Most USB cables have 4 pairs of wires (2 for data transfer and 2 for charging).
- The thicker the wire, the better the performance. Some manufacturers save on material by reducing the cross-section, and thereby increase operating time. Take this factor into account when choosing a cable; if your priority is to quickly charge your phone, then take a thicker wire.
- The longer the cord, the slower the charging. The longer the length, the greater the resistance. High resistance increases the time it takes to fully charge the device.
