CONCLUSION
The AC-42K EU power bank by Enerpad is a beast not only in size but also in battery capacity since it's 16 internal rechargeable lithium-ion batteries (2600mAh each) add to slightly less than the advertised capacity of 42.000mAh (around 41600mAh according to Enerpad). Now although it's certainly very useful to have two 3.4A/5V USB outputs (plus a USB type-C output) but at the end of the day quite frankly you will never get to come even close to the advertised capacity of this powerbank. As we've mentioned many times in the past this of course is largely due to the voltage conversion (and then there's also a slight conversion loss) between the internal batteries (3.7V) and the USB ports (5V) so after 2 full weeks of testing with our two USB testers we recorded up to 28200mAh (we decided on measuring all over again every single powerbank we have here so from our next review we’ll also be adding charts so you will all know at a glance what you are getting in terms of total battery capacity). Now although we did expect slightly more (conversion loss was obviously a tad more than expected so we do hope Samlife/Enerpad looks into that) this is by no means a small number especially considering that it's almost twice as much compared to what we got from our last powerbank review of the Zendure X6. Of course the 2nd selling point of the AC-42K EU model (just like with similar models) are the two AC ports (200W total output) which allow you to use the powerbank with a plethora of electrical devices such as fans, TV's, desk/floor lamps, laptops and even small refrigerators (we used a couple of large fans and one 32 inch LG TV without issues).
Even though Samlife (Enerpad) is doing extremely well in China they have zero presence in the USA and EU markets so here (at least for now) they actually act as the OEM manufacturer for other "local" powerbank brands like Chargetech and Xtorm. So, At the time of this review the 42k model by Chargetech retails for USD220 inside the USA (Amazon.com) whereas the AL490 model by Xtorm currently retails for 263.75Euros inside the EU (Amazon.de) and yes it costs quite a bit. Still considering that you're getting almost twice the battery capacity of for example the Zendure X6 (which is still considered a very high capacity model) along with two AC sockets featuring a total power output of 200W and honestly, I’d say things look pretty good. Overall, we were very satisfied with the performance of the AC-42K EU powerbank by Enerpad, sure it may not be the best all-around model out in the market today but it offers exactly what most consumers looking for an extremely high battery capacity would want and for that it gets our Golden Award.
