Maybe this web article provides some "de-coding" of Ankers product names? https://www.powerbankguide.com/anker-powercore-vs-powercore_plus_select/ You can charge an USB powerbank by almost any USB charger - also it is strongly advised to have a charger that can deliver the maximum Amperes the USB powerbank can take as input - most can "eat" 2A or 2.4A. If you use a smaller charger that can only delivery 1A or even 0.5A it does not only take (much) longer to charge the powerbank, but also the electrical and thermal stress on the smaller charger can cause its earlier "death". Edit: @kikaida correctly added re QuickCharge (2.0 or 3.0) which I forgot to mention. If the smartphone/tablet can take QuickCharge (higher voltage + ampere) so should your powerbank provide and the charger as well. As described above: besides the powerbank and the charger the USB cable is important too! Either use the cable that came with the powerbank and use it (as most times recommended by the manufacturer) and/or use other high-quality cables - and (!) verify that the voltage (most times between 4.7 and 5.4 Volt) and the Amperes are up to what the powerbank can take; an USB powermeter is your best friend (and helped me to identify cables that work in specific scenarios like charging my smartphone via my laptops USB port with 1.2A (max) while other cables do only 0.5A, which do 2A when used with a wall charger - very confusing and non-consistent, IMHO). Depending on your environments, a hard case may be a good idea to protect the powerbank from dust, water and (some) drops. If you can afford it, go for it for transport (not sure if this is always a good thing depending on temperatures, etc.). Others may share their experiences with those boxes.
