Portable aux battery

[BroncoHauler]

All the talk about heaters and mattress warmers got me thinking about my Winter camping in my trailer. I have a single Group 31 AGM battery (92AH) so I'm very cautious about my battery usage.

I started looking around at Amazon regarding portable batteries, and came across a couple that seem promising for powering a mattress warmer or two without effecting my house battery. Sort of like the Goal Zero solar generators, but with Li batteries. 400WH, so about 33AH at 12V. FYI, Goal Zero Yeti 400 Solar Generator (29#s), vs. Anker 400WH (just over 9#s).

I was literally just doing the exact same thing.

Why couldn't you get along with a cheaper battery like one of these?

We run a string of 8 Goal Zero lights off of a similar battery for our camping trips. They run several hours a night for 2 nights and draw the battery down to about 80%.

I actually have one of these (received as a freebie for buying a garage door opener). Carried it as backup in my trunk when one of my cars had a battery issue. Nice, but kind of heavy and bulky.

I've been thumbing around about this too. Not happy with the info on the batteries in the Anker. I tried emailing them too, specifically about what type of Lithium was in there. Got the same answer you did. I think Anker is running a bot response.


You could consider just chucking another battery in the car? Depends on how many nights you need it? 100 Ah AGM $160 + $6 for clamps. Seems like it would work real well for 1-2 nights.

Have you tested out the bunk warmer yet? I've got one and just tested a little inside but seems like it might do a real good job cutting the chill on a cold night.


Think there is a way to setup a DC inline timer to have it click off after a few hours but click on before you want to get up? Might conserve the batteries lots.

I've also wondered about the performance of Li-ion in cold temps and if this could be an issue to using one of these power packs?

The Anker PowerHouse is down to $329. May have to start seriously thinking about picking one up.

Ive always liked that due to its size and how clean the panel is. I might bite on this too. Wonder how long it takes to fully charge it off 110 AC?

6 hours according to the Anker website (which has a little more info than the Amazon page). It is out of stock on the Anker webpage though.
