The
LESHP 27000 mAh Power Bank appears to be identical to the Omars 24000 mAh. It takes just under 3.5 hours to fully charge the LESHP from empty to full. I placed 3 cold (not hot)
Spark batteries (each discharged to 20%) in the Fly More Spark 3
battery hub and connected it to the fully charged LESHP AC outlet with the hub AC power adapter. They all started charging simultaneously. The
battery in the furthest hub bay from the hub plug connection (bay 3) reached full charge in about 50 minutes. The other 2
batteries ceased in about 65 minutes. All three
batteries were at 96-100% after charging.
I discharged the the 3
Spark batteries down to 20% again, let them cool, and performed the same charging procedure as above with the LESHP partially discharged from the first 3
battery charging. All
batteries started charging simultaneously as before. Three of the four LESHP lights were lit at the start of the second charge but within 5 minutes went to 2 lights and 1 light at 25 minutes into the charge. At 32 minutes that one LESHP light began blinking. At 37 minutes into the charge the LESHP stopped charging. The
battery in the bay furthest from the hub plug (bay 3) was 69% charged, the middle bay was 92% charged, and the first bay was 72% charged. The middle bay
battery (92%) stopped charging before the other two on the second charge. This was not the same
battery as had been in bay 3 in the first charging. (Btw, that first bay 3
battery is a $39 refurb
Spark battery from ebay. It was in bay 1 on the second charge. I have had no issues with the refurb
battery.) The 92%
battery stopped charging before the others. Apparently the LESHP is programmed to stop charging the highest charged
battery at some point and to concentrate on its weaker mates.
From giac's comments earlier, the LESHP would also be expected to charge less than 6
batteries. Although rated at 99.9 Wh capacity, it would still at best charge 5.88
batteries (99.9/17). Furthermore, the
batteries in the test were at 20% rather than 0% at the beginning of the charge. This suggests planning on charging a total of 5
Spark batteries with a fully charged LESHP 27000 mAh Power Bank.
I have ordered a
Smatree SP92 Spark 3 bay portable charging station (currently 3 left at amazon with a 15% discount for a before tax/shipping cost of $62.89). At 92 Wh rated capacity, it probably wont fully charge 6
batteries either. But it is lighter and smaller than the LESHP and doesn't require the Spark hub converter. There is the trade-off of it being useful only for
Spark batteries. Nevertheless, I'm looking forward to comparing it to the LESHP.
