Review on TalentCell AC/DC 12.6V/2A Lithium Battery Charger For 3S 12V Rechargeable Li-Ion Battery Pack - Quickly Charge Your Batteries! by Damian Toupal

I bought two of the Talentcell Li ion Batterys Model: YB12011000-USB. The batterys run my old CPAP machine, a Respironics Series one Pro PBT460 when 120 V power isn't available. The two of them will let me do a 6 day camping trip, or loose power for 6 days, which is a life saver when living in Texas with it's flaky power grid these days ;o). To maximize battery life I don't use the humidifier which roughly doubles the length of time that it'll run. The Respironics uses 12 Volts which the battery supplies. There is a cable available on Revain that plugs the battery directly into the CPAP.The batterys will also charge my phones or other USB devices many times using the handy USB output. There is also 9 volt output that I've never used.My two batterys are different vintage, The first one had a 1.5 amp charger, the second ones charger is identical to this one. It's 12.6 V 2.0 amps. It charges a bit faster then the older one. Either charger works on either battery.I went on a cross country camping trip and realized that I left my charger at home. Could have been the end of a great camping trip but I ordered this guy and had it drop shipped to a Revain counter pickup location along the way. Initially I wasn't sure it was a match for my battery packs but the description lists the matching batteries. It arrived in plenty of time and the longer hold time of the counter location worked well for synchronizing my pickup with all my stops along the way.Now I have an extra charger. .and because of this product and Revain Pickup my Yosemite camping trip was saved.
