ADATA PV100 Power Bank Comparison
Here’s my whole kit of chargers, surrounding the primary smartphone that they support. The ADATA PV100 Power Bank is the smallest of the devices, both physically and electrically. Starting with the PV100 with 4200mAh and continuing counter-clockwise: the AGPtek Solar-Powered model has 5000mAh of battery capacity, the IOGEAR GearPower Power Station has 6600mAh of capacity, and the RAVPower PB07 on the far left has 10,400mAh of battery capacity. They all function pretty much the same; although the AGPtek solar unit has a few extra tricks up its sleeve, in addition to the integrated solar panel. It’s the only one of my old battery packs that allows pass-through charging, where you can hook up one AC-powered charger to the battery pack, and also have another device connected to the battery pack that gets charged at the same time. As it turns out, the ADATA PV100 Power Bank was able to do this trick, as well. This is an undocumented feature, for both units. I’m not sure what prompted me to try this in the first place, but it definitely only works on selected models. This feature was more important back before wall chargers started sporting dual USB output receptacles. Today, you just hook both devices up to one charger, in parallel. Back in the day, the only way to charge two devices from one charger was to connect them in series.
Looking from the top, in the last picture, there wasn’t a whole lot of difference in the sizes of the various battery packs. Looking at them from the side is a different story! On top, at just 8mm thick, is the ADATA PV100. Second from the top is my AGPtek solar-powered unit, at 17mm thick and carrying 5,000mAH of charge. The largest of the units is third from the top, and it’s the fattest of the bunch at 21mm. It makes no apologies for its bulk though; it just shows you its 10,400mAh of Li-Poly muscle. On the bottom is the IOGEAR GMP6600P, which holds 6,600mAh within its relatively slim 14mm case. It’s slightly larger in the other two dimensions, relative to the other three units, which does make it feel slightly bulkier in use. You can see from this view that some have dual charging outlets, and the others have only one. Three of them are strictly 5V units, and the AGPtek has a switch-selectable output voltage of 5 – 6.5 – 9 – 12 VDC. They all have slightly different personalities, and the ADAT PV100 is now my go-everywhere power pack. It’s just the right size to make it easy enough to carry, no matter where you’re going.
One thing to remember with all these devices is that no matter what output you use, the electronic device you are charging with it will almost surely limit the amount of current that flows into its own battery. So, despite the 2.1A label on the battery pack output, your phone or Bluetooth headset will probably limit the charging current to 1A. In other words, don’t expect faster charging times with a battery pack than you typically get from your AC wall charger. I’ve been using the ADATA PV100 Power Bank for a couple weeks now; let’s see what we can come up with for testing purposes. It wouldn’t be Benchmark Reviews if we didn’t log some test miles.
