Is Anker a good power bank manufacturer

Which power bank manufacturers are recommended?

There are masses of power banks in stores, from various manufacturers. But which power bank manufacturers are recommended?

For Techtest.org I already had over 100 power banks from various manufacturers in my fingers and was able to form an extensive opinion accordingly.

So, which is the best power bank manufacturer and which one should you keep your hands off of?

 

Which power bank manufacturer would I recommend?

There are dozens of good power bank manufacturers! If I were to say “only buy models from manufacturer A” then I would do many manufacturers injustice. Ultimately, it also depends a little on your requirements.

For example, Anker has many very good power banks, but is not very well positioned for notebook power banks. AUKEY has some very good models, but also a few bad ones.

Nevertheless, I would tend to classify the following power bank manufacturers as good and trustworthy:

Manufacturers with their own designs or primarily their own designs are printed in bold. Own designs = the power banks are developed by the manufacturer themselves or developed exclusively for them. The others are finished designs that are bought in wholesale.

As a rule, good and reliable power banks come from manufacturers

  • A website (you won't believe how many "manufacturers" don't have them)
  • A unique design
  • A clearly visible manufacturer branding (a good brand is usually proud of its name)

In my private life, I currently trust power banks from Anker, RAVPower and Xtorm the most.

 

Premium power banks

If you want to buy a power bank, you usually have the choice between the cheaper China models (Anker, RAVPower, AUKEY, etc.) and the "premium" manufacturers.

I include:

As a rule, power banks from these manufacturers are comparatively expensive. For example, Belkin sells a 20000mAh power bank with 30W USB PD for 130 € with the Boost Charge. An Anker PowerCore Speed ​​with comparable data costs 55 € or an Omars OMPB20PW40GYCJNL-U 38 €.

Yes, the power banks from these manufacturers are good, but not better than a model from Anker, RAVPower and Co, often the opposite. You pay a good deal for the name and the design, often a 100% + surcharge.

I only want to protect Xtorm here. Xtorm Powerbanks are usually not cheap, but technically very strong!

 

Power banks are not rocket science!

Certain safety precautions must be observed for all devices with lithium-ion batteries, as these can otherwise be quite dangerous, but building a power bank in 2019 is no longer rocket science.

Most power banks in retail use standard chips, which control and take over voltage, short-circuit protection, protection against deep discharge, etc.

These Lithium Ion Protection ICs are available from well-known manufacturers for a few cents in wholesalers. You even get masses of completely finished “Powerbank Controllers” for well under one €.

Therefore, in principle, it hardly requires “higher knowledge” to produce a simple and sufficiently secure power bank.

I haven't come across a really bad power bank in the last few years, from a legitimate manufacturer who doesn't try to cheat you!

Yes, there are models that charge faster, have fancier cases, more charging standards, but if you just want to power your smartphone at a reasonably acceptable rate, then almost every model can do it!

You don't need to expect problems or even a fire, even with the very cheap models. Lithium ion cells are now very solid, just like the protective electronics.

Only I don't trust the Auto-Starter Powerbanks! With these, protective electronics are partly bypassed and the proprietary power supply is not the yellow of the egg.

 

Your own power bank at Alibaba

But where do these thousands of power bank manufacturers come from? Manufacturers of everyone pop up on Amazon again and again: Pxwaxpy, Yacikos, VOOE, Feob, etc.

These manufacturers usually don't even have a website, how do they know how to build a power bank ?!

Alibaba!

Alibaba is an Asian wholesale platform. Here you can buy ready-made power banks from large manufacturers. If you take quantity X you will receive a logo imprint, if you take off even more, you can screw on the design of the housing, etc.

If you are interested: https://german.alibaba.com/trade/search?fsb=y&IndexArea=product_en&CatId=&SearchText=Powerbank

You will also find a few familiar faces here. For example, manufacturers such as Hama offer power banks, but of course they don't build them themselves. Hama is not so big that it is made especially for these special power banks, it is "only" bought in and provided with the respective logo.

See E.g.

https://www.amazon.de/Hama-USB-C-Power-26800mAh-Power-Delivery-Anthrazit/dp/B07NH3TKCV/ref=as_li_ss_tl?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3 % 95% C3% 91 & keywords = Hama + 26800 & qid = 1568652423 & s = gateway & sr = 8-2 & linkCode = ll1 & tag = techtestorg-21 & linkId = 44b3c2200689f5e2d79f7f9c549577fa & language = de_DE

and

https://www.amazon.de/FLOUREON-26800mah-Powerbank-Schnellladen-Ladekabel/dp/B07KYFWR9D/ref=as_li_ss_tl?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords = 26800 + 60W & qid = 1568652434 & s = gateway & sr = 8-6 & linkCode = ll1 & tag = techtestorg-21 & linkId = f09d2f6a24ed5305d88f297ada7a4ba9 & language = de_DE

It doesn't have to be the same model here, but these will almost certainly be from the same paver.

Of course, it is also not bad to just buy a model, but in-house developments are often "more interesting".

 

Beware of black sheep among the power bank manufacturers!

When something looks too good to be true, it often does. Most of the power banks that you get from Amazon and Co. are legitimate models, which are okay in the worst case and very good in the best case.

But there are also manufacturers who simply want to cheat you. As a rule, quite small power banks with far too high capacity specifications are sold here. This risk exists especially on platforms alla AliExpress.

These power banks mostly work, but then only offer 9000mAh instead of, for example, 30000mAh.

I would like to give you a list of these fraudulent models here, but the manufacturers usually disappear as quickly as they appear.

Such a "problematic" manufacturer would be, for example, SunyDeal https://tetest.org/eine-30-000mah-powerbank-oder-etwa-nicht-die-sunydeal-30000mah-powerbank-ein-wenig-powerbank-grundwissen-und-infos /

Identification marks for a possible fraudulent power bank:

  1. Very high capacity, low price
  2. Often very compact
  3. Generic design, without major manufacturer branding, etc.
  4. New and unknown manufacturer (or this is not even specified)

 

How durable are power banks?

There is no general answer regarding the durability of a power bank. Ultimately, this depends on various factors.

First, of course, we would have the battery cells here. As a rule, you can say that a good lithium cell should be able to withstand 500 cycles. Most power bank manufacturers also confirm this value.

With very cheap power banks there is only the risk of getting second-hand cells. In some cases, used but still functioning battery cells are removed from notebook batteries etc. and installed in power banks or other devices.

Of course, you can't see this from the outside of the power banks, but here the lifespan is uncertain. The capacity of lithium cells is very stable up to a certain point, but then quickly collapses.

If you buy a cheap power bank that has used cells, then it may be that this + - has the specified capacity, but already degrades significantly after 100 cycles.

With large manufacturers of all anchors, Xtorm, RAVPower etc. you can be quite sure that you will receive new cells.

Most of the time, the cells don't break in the first place. The electronics are much more sensitive here. Of all my power banks, only three models have died so far. In each of these three, the charging electronics broke.
