CONCLUSION

   When we received the MP-23000A sample by XT Power we couldn't believe that it had a battery capacity of 23000mAh so we started testing immediately with every smartphone, tablet and portable battery we have here only to find out that after the first charge the battery capacity was at around 15000-16000mAh so although quite impressive as well still it was nowhere close to the advertised 23000mAh. As it turned out we had to empty and recharge the battery 4 full times (takes quite a bit of time) to hit a steady 16000-17000mAh and although still somewhat far from 23000mAh we consider it quite normal since we've yet to see a single portable battery offering 100% of the advertised capacity. However that's not all and so the available power output ports and voltages that let you recharge pretty much anything portable and the LCD screen indicating the remaining battery life are also great features which we haven't seen before. The only downside we can think of is the sheer size of the MP-23000A which is in fact almost identical to a small 7" tablet and although we do realize that you need to make sacrifices to have such a massive amount of power with you at all times some people will probably not like that.

   Although XTPower has designed and manufactured a portable battery with many times higher capacity than most solutions in the market it seems they are following a very aggressive pricing policy since currently the MP-23000A Ultra-High Capacity External Power Supply Battery Pack retails at around USD90 inside the USA and 108Euros inside the EU (Amazon.co.uk). Certainly if you're 100% that you will never need such a high capacity portable battery pack i see very little reason to even consider purchasing but if that's not the case and you like camping or generally staying away from electricity for long periods of time then i can't think of a better device to accompany you. Sure it's not what many people would call small but it's actually quite thin and that makes it very easy to carry around inside a bag. Size aside until a better portable battery comes along the MP-23000A has secured a place in my backpack and because of that it gets our Platinum Award.
