Excellent Combo Product! March 13, 2024 Reviewer: Mike from Fayetteville, TX United States   I needed additional Nitecore 21700 batteries and for just a few bucks more received an 80 Lumen ‘Lantern Type’ light that attaches to the battery by a magnet. Also included is an adapter USB charger that also attaches to the battery via magnets. And, did I mention the light lasts a very long time!  A great combo product from Nitecore!

Buy two units and you'll thank me later February 29, 2024 Reviewer: mike h. from Corpus Christi, TX United States   I purchased one of these and was impressed with it so  much I ordered another one the day I received the first one.  The only drawback is that it will cost me shipping again but that's ok.  Trust me when I suggest you buy two units if you buy one at all.  You will be glad you did and when you do you can thank me here.  One more side note is that I put the charging base on the bottom of the battery and the light on the other end and it works at the same time fyi.  So if you needed both utilities off same battery you can do so.  Pretty cool device I have to say.

Superior Battery October 9, 2023 Reviewer: Shannon Dolte from CARMEL, NY United States   Proprietary design aside, this is one high density battery with high output. Previously I had been using only the 18650 size. Bigger is better (typically) when it comes to batteries. Was this review helpful to you?

Part 2 - 2nd battery test August 23, 2023 Reviewer: Texjsleigh from Texas   Battery number 2 - 21700 i series battery - NL2150HPi.  Results of two batteries are consistent.  Yesterday, battery number 1 got phone charged to 91% of phone battery capacity.  Today the second new battery achieved 92% of my iPhone battery.  So efficiency is 0.92 x 3046mAh/5000mAh = 56.0% of the claimed power Bank battery capacity. Aug 23, 2023 8% at 1:09pm 55% at 1:44pm 97% at 2:50pm 98% at 3:15pm 100% at 3:49 and battery indicator blinking low charge and at 5:13 battery indicator shows completely exhausted.

Cool product but subpar results August 23, 2023 Reviewer: Texjsleigh from Texas   I just ordered two batteries for weight savings over my 10000mAH hard power bank.  My iPhone has a 3046mAh I use for gps backpacking.  5000mAh/3046mAh =1.6. But rather it achieved 0.91.  Charging was in 69 F degree room.  Phone was not used other than background incoming emails and texts. 21700 i series battery - NL2150HPi took my phone from 40 to 100% yesterday.  Today it took my phone from 24% to 55%.  So 60+31=91% in one battery.  So consider this in planning how many batteries you need. 1- Aug 21, 2023 40% 10:05am 86% 10:53am 96% 11:35am 100% 11:42am  2- Aug 22, 2023 24% 7:14pm 55% by 8:20pm and battery bank is drained Was this review helpful to you?
